Getting rid of laptop ants

A laptop ants solution.

Have you got laptop ants? Here's a simple, bait free solution. Do this and the ants will simply leave by themselves. I've had the same problem and this fixed it.

Ants in a laptop can be scary. What are they eating? Microchips? Don't panic, just follow these steps and the laptop ants will be gone by morning.

Laptop ants.

Laptop ants.

What you'll need to remove laptop ants.

Step 1.

  1. You'll need a tray which can hold water.
  2. You'll need something stable which can sit in the water. If you use a bowl it needs to be heavy or it will float.
  3. You'll need a stick or wooden cooking spoon or something about that length which will not slip if you lean it.
  4. You'll need a laptop infested with ants. This solution is for serious laptop ants. If you've only got one or two, just brush them off.

Assembling your laptop ants solution.

  • Now fill the tray with water. It doesn't need to be full. Just enough to cover the bottom. Put it somewhere where it will not be disturbed.
  • Place your stand in the center of the tray.
  • Making sure the laptop is off and unplugged, place it carefully on the stand. Be sure that nothing but the stand underneath is touching the laptop.
  • Lean the spoon or stick so that it touches the laptop and the surface that the tray is sitting on.
  • Leave the set-up overnight.

Why it works.

Why would the laptop ants leave via your spoon bridge?

Ants have powerful survival instincts. Either the ants are in the laptop eating food you've dropped there or they've moved in. In either case they scout the area at all times. Once they realize the chemical trail which got them there (following other ants) no longer leads home they'll look for an alternative. The spoon will eventually be found and they will eventually all follow it. One trail over water is not acceptable and they will not use it to return.

I grew up in India and my father told me (panicky as I was - I had work to do) of this solution. I didn't believe it would work but it was risk free so I did it. The next morning all the ants were gone.

If you've got laptop ants to get rid of, try it. It works.

If you've tried this solution, you are an entomologist in outrage or have any comments or questions, please leave one below. If you've got a friend with ants everywhere and a laptop tell them about this laptop ants solution!

You are most welcome Micha. Anty-thing I can do to help!

Micha ELa from Philippines on April 09, 2019:

You have just deciphered ant psychology. Kidding aside, I wish I had come across this article when I was so stressed over the same situation. I wouldn't have had to buy one again. Thank you for sharing. I'll keep this bookmarked just in case.

Do ants harm your computer?

Susan Rand on August 20, 2018:

What's the purpose of the water?

Fertile Forest (author) from Sydney, Australia on June 01, 2018:

Hello hello, reading your comment I think you may be confusing ants with small fish or tiny crustaceans. To my knowledge, ants do not use water to nest. Also, once you spray things with 'bug killer' the normal behavior of the ants, ie: leave in an orderly fashion, is replaced with new behavior, ie: run around like crazy! Patience is required for this solution. If however, you choose to employ fire, I wish you good luck.

hello on June 01, 2018:

this doesnt work.. they nested in my laptop. they used the water for their nest so i sprayed the water with a bug killer, some died. they wouldn't just go out so i had to crush every ant that goes out. once they realized this, they stayed inside. i didn't know that they stayed inside so i used it the next morning thinking that it was fine but no. so i leave my laptop on all the time and i just see dead ants under it the next time i use it. i'm assuming that they couldn't take the heat. so i say

KILL IT WITH FIRE! (actually, heat. but fire sounds cooler)

capinHI on September 24, 2017:

Thanks for great advice and the laughs -- some of the posts are hilarious.

I live in Hawaii and use a similar method to keep ants out of pet food (i.e., place the dog food bowl in a second, larger bowl that has an inch of water in it), or climbing up table legs. But I didn't know about providing a spoon as an exit route.

I'm not an entomologist, but my experience from living in a tropical climate is that "flying ants" are usually termites. So the people posting about them probably have bigger problems than just ants in their keyboard!

anonymous on September 02, 2017:

Hi. Wouldn't the ants come back and make it a permanent trail or something?

Lacey on June 08, 2017:

We haven't had a problem with laptop ants, but we've had common sugar ants infesting small kitchen appliances. Apparently they like the AC hum from anything plugged into the wall, and also the warmth. We've found them in a digital clock, a coffeepot, and similar appliances.

bud on May 14, 2017:

it works ! only 1 ants remain in the laptop ! you deserve a nobel prize ! you will be knighted by the queen ant !

AntsBeGone on April 02, 2017:

THIS WORKS. Had quite the infestation going on. No food around my laptop; they must have loved it for other anty reasons. Completely gone overnight. Turned my laptop off, balanced it on four upside down custard cups on a tray, poured water in til there would be no escape, and leaned a wooded spatula from the keyboard to the desk. Done and done. Thank you!

I accidentally tested this method a couple months ago with a houseplant. There was a large colony living in the roots and tending citrus scale for food. When I started watering the plant more often (until the dish it sits in was full of water) they moved out. No part of the plant touches the ground, so they must have had to wait until the flooding subsided, and left without my noticing them going.

AMK on January 12, 2017:

Forest, a question: I have this problem, but the only 'stick' available to me is a broom. Is that too wide to function properly? Is there a particular narrowness required? Thanks!

Fertile Forest (author) from Sydney, Australia on January 10, 2017:

MacBook Ants in Thailand, have you met aarona? You guys have a lot in common. Good luck with your ant related issues.

aarona on January 09, 2017:

Haven't tried this yet but I'm glad to see a compassionate solution to the problem, and loving the humor of your replies!

Person who got ants on Laptop on October 16, 2016:

i dunno between laugh,cry,panic......

they finally attack my laptop

i will never walk on ant again.....

they'll REVENGE 2 me......f*ck

hope this work


angieangelicdelacruz@yahoo.com on August 06, 2016:

It is happening to my laptop that's how I found this site. :(

Karan Raj Kohli on May 29, 2016:

The problem is that.... ants only come out when i turn off the lights and one more thing THEY CAN FLY (wtf) help plzzzz... :(

Fertile Forest (author) from Sydney, Australia on February 26, 2016:

T, I'm sorry to hear its not worked for you yet. Is the laptop over water? Is the bridge the only way in or off? Maybe your laptop is extra nice or the ants are stubborn. Don't bother them or disturb them, make sure the bridge is the only exit and give it one more night?

Andy on February 25, 2016:

Hello, I live in the Seychelles and I got the ant problem (sigh) I tried your setup and left it overnight, so like 24 hours already. I am still seeing ant movement over the bridge: coming out of the laptop and into the laptop as well. I haven't seen them carry any eggs thoug. Should I do something else? How much longer should I let the setup, I am worried they just like my computer too much. T.T

xmarksthespot on February 16, 2016:

this happened to me on different devices lol never ate near them,

often they nest near the power supply/electric current.

they tried nesting on my keyboard, laptop, HDD, tv and ps4 lol

Kazzzza on November 25, 2015:

Hi, and thanks for this helpful information. I am going to try this method tonight but wanted to ask if the spoon is in position where it is touching the computer and the table.... Where are the ants ending up??? Do they make their own way to the water or do they end up on the table and around the area of the table?

Fertile Forest (author) from Sydney, Australia on October 25, 2015:

Jeco, thanks a bazillion for your initial message and the follow up. Not many who say they will come back actually do. So happy it helped you. Cheers.

herbman76 on October 25, 2015:

Thanks glad to found this.

Jeco on October 01, 2015:



Like I said, I had my laptop for 3 months, and the other night while I was using it, ants seem to came out of my laptop, usb ports, vents, keyboards etc! I was squishing them with my hands as I see them but the more I squish the more that came! I was losing hope until I stumbled upon this thread. I tried it and I thought to myself, well there's no harm in trying, and IT FREAKING WORKS.

I did the process starting 12midnight, went to sleep, went to the office in the morning, and when I checked it out the next night around 8pm, there was ONE ant on the laptop, squish it, killed it and there was no signs of ants ever since that night!

Since then, I was placing my laptop on that "MOAT" without the spoon overnight, and I'm thinking of getting an airtight food container for my laptop to keep the ants out, Ants are attracted to electricity and waves of the laptop.

Better safe than sorry, and prevention is better than cure.

Thank you again Fertile Forest for this!

I commented so that I can personally thank Fertile for the time, effort and dedication he gave us! If I can only see you personally I would shake you hand and treat to a Pint!

Thanks man! Thank you!

Jeco on September 29, 2015:

I'm going to try this tonight, best of luck to me.

I just had my laptop for 3 months, and tonight there ants all over, I'm going to do this method before I go to sleep.

And thank you Fertile Forest for your dedication in helping us with our laptop dilemma, you truly are a wonderful saint :) The world needs more people like you.

I will surely update on this. Thanks again Fertile :)

Maj on September 17, 2015:

@Fertile Forest

Hello Good Day ,

I just want to let you know that it perfectly works .


I was reading all the comments on this but no offense , it made my day. Common Sense is the Key . I am LOL!! (f'or the f'reakin comments of' them)

Fertile Forest (author) from Sydney, Australia on August 14, 2015:

To answer your question Kurt, I'm afraid I don't have another stronger strategy. You might allow the ants more time. Ants need to return to their nest each day.

Fertile Forest (author) from Sydney, Australia on August 14, 2015:

This solution doesn't work on aunts.

Kurt on August 14, 2015:

I tried the procedure and a few aunts (admittedly fewer than before) are still hanging around my keyboard. Can you advise something a little stronger?

Fertile Forest (author) from Sydney, Australia on August 12, 2015:

Dean, I forgive you. You have seen the light and chosen the true path of understanding of our six-legged friends.

As Jack Nicholson says in Mars Attacks, or was it Rodney King? Anyway, someone says, "Why can't we all just get along?"

Well, we can just get along. So git' along little doggies, (here I refer to ants), and leave them laptops alone!

Dean on August 11, 2015:

I'm amazed by the longevity of this topic, and impressed by your dedication to helping ants and laptops coexist peacefully. The modern world is a difficult place to navigate and you, like those who follow your instructions properly, give us but one path to walk. A path that leads us (and our ant friends) to a life without laptop ants, where we (ants and laptops) can truly come to appreciate the virtues of our counterparts in this ant-nests-in-laptop world.

I shamefacedly admit that I've snuffed out the lives of several ants which have come crawling across my laptop screen, but after seeing the monk-like patience and virtue of your ministry to your fellow laptop users, I see the error of my ways. No longer must I kill to compute, and for that I thank you sincerely.

Fertile Forest (author) from Sydney, Australia on August 10, 2015:

I'm not entirely sure what you mean by 'plate', the instructions call for a tray with a bowl in it. As long as the laptop sits above the water and doesn't touch anything but the stand (I used a bowl) underneath then that's fine. The bridge (I used a wooden spoon) should touch the laptop and the table it all sits on. The spoon shouldn't touch the water. Good luck!

frost_wolf on August 10, 2015:

Hey! Currently trying this method out. The laptop is too big for the plate. Is that okay? The spoon that I'm using isn't touching the plate but the table. Not sure if that'll work too.

Fertile Forest (author) from Sydney, Australia on August 09, 2015:

yS dat c%d hpn bt Y wud dem ants cum back?. dey sed "this crib iz whack, I'm gon go"

rumaan_munnu on August 08, 2015:

ok its fyn but ants can cm back through da same path(i.e spoon made like bridge) which we hav aranged to leave ants frm laptop

Indika on August 04, 2015:

I got a Yamaha keyboard when i was young, once it crashed and I opened it, viola! ants have gone under the microprocessor with their tiny white eggs and the formic acid has corroded the pins of it. So i had to replace the processor and it took more than the keyboard itself lol :P Now i am so scared if I see an ant poping out from the keyboard from the laptop haha. I couldnt give this to service coz i need the laptop to do my work everyday sigh.... thanks for the tips !

Fertile Forest (author) from Sydney, Australia on July 31, 2015:

I recommend doing this overnight as ants exhibit different behaviours during daylight and night.

Fertile Forest (author) from Sydney, Australia on July 31, 2015:

Yes, poison is always an option. I hope your laptop isn't laptoxic for too long.

chié on July 30, 2015:

what I actually did was rub bug poison (the chalk/powder kind) on my laptop... it got rid of the ants and they didn't come back... probably died in there... but great idea tho.

paulinenicole on July 19, 2015:

Also, should this be done only during nighttime?

paulinenicole on July 19, 2015:

Hello! I tried this last night and I observed that there were too many ants in my laptop. I left the set up overnight only to find out that the spoon was not attached to my laptop anymore. I checked the water and there were a few ants that drowned. I didn't get rid of them completely because a few were still crawling and I saw some peeking through the keyboard.

Should I just repeat the set up tonight?

Fertile Forest (author) from Sydney, Australia on July 04, 2015:

Thank you all for your kind comments and feedback. I really appreciate it. Sorry it took so long to reply. In answer to some questions:

Yes works on a Mac. Or any device which can be placed as the instructions lay out.

The spoon can be placed anywhere it won't move overnight and forms a bridge from device to table.

I would not suggest adding or using repellents to the water or the computer. You may confuse the ant's natural instincts to leave.

Ants in your laptop are unlikely to directly damage it, such as eat it, however they may bring dirt in to build a nest over time. This could damage it.


Ruch on July 03, 2015:

Brilliant... I have ants all over my keyboard and I'm going to try this solution tonight! I dont like to kill them, so this is perfect, thanks!

sweetants on June 15, 2015:

i actually used a vaccum cleaner it worked fine as well

Wajih on May 18, 2015:


I live in Lebanon, and I spotted a normal ant crawling around my laptop a week ago and thought nothing of it and let it be. However, I have yet to see that specific(not the exact ant, I mean worker/scout) ant again. And instead in the last two nights, only ants with wings have emerged. I decided to look for solutions in case a colony was or is going to be living in my laptop.

I have a Lenovo Y510p, the ants might not be local(from my house) since I've taken my laptop to my studio at the university where ants have been spotted on the tables before.

I'm trying out your method, however I've yet to see any activity. I'm worried I might have scared them into staying inside by killing a bunch of the winged ones (which usually go looking for mates), when they had emerged.

One more thing I'm considering is the possibility that I might have interrupted their moving in when I took my laptop home from the studio. Could that be why I'm not seeing so much activity and just reproductive ants?

Thanks for the solution,


NotAntz on May 18, 2015:

We are a human, not antz typing from underneath keyboard. This method not working. Hail the Queen.

Chandru on May 13, 2015:

Man, you are awesome.

I did this technique by keeping the laptop in the method suggested by you. But I was not satisfied with the pace in which things were moving. So I googled up on natural ant repellant and i found many of them.

I decided to use a mixture of 3 repellents - lemon juice, pepper powder and salt to make it an absolutely disgusting smell. I put the three of them in the water and i crossed my fingers. Nobody likes to live in a stinking environment, so this technique is a slight improvement on your method. So far i have seen more than 40 come out and it's 24 hours since I started this experiment. I guess I will have to keep it for some more time to ensure they're gone.

Thanks for your idea, would also like to know your feedback on my idea - Chandru from Sri Lanka

AS on May 04, 2015:

Hi there! How long until after set-up will it take until ants start coming out?

NC on May 04, 2015:

I own a macbook pro. And I'd just like to ask.. which part of the mac do I put the wooden spoon? At the back or in front (near the trackpad)? I'm currently setting it up and I'm not sure where to place it!

Al on May 04, 2015:

does this work on macs?

Jon on May 01, 2015:

I'm having this same problem but with my Xbox One. Giving it a try! If it works you're my hero.

NJ on April 25, 2015:

Help I have Toshiba windows 7 and ants are crawling in!!!Im only 12 and I don't know what to do!I am scared this won't work!Will my computer actaully break if I don't stop the ants!?

Mr. Nitecroler on April 04, 2015:

How about put the laptop in a plastic bag, put a moth ball in it, seal the plastic bag.

Mrs Sheila Cooper on March 30, 2015:

Thank you so much for this suggestion I found my computer full of ants 2 days ago even though it is so early in the year. I did as you suggested and every ant has gone. It is so simple and it works - thank you.

Carl Ingalls on March 23, 2015:

Please remove my email address from my last comment. I did not mean for that to be public. My name is ok.

KelseyT on February 24, 2015:

I've got a laptop from my school which I seldom use save for rendering things in Maya/Source Filmmaker, and I always unplug it and remove the battery when it's not being used so that ants don't find it attractive, but they still love to swarm it. Hoping this solution will work.

CJP on January 27, 2015:

I got a surprise tonight while using my Nexus 7 tablet. Dozens of ants cam pouring out of the earphones hole. it was a bit embarassing as I was at a friend's house. I dropped it into a zip lock bag to bring it home.

Then I found your blog. Thank you so much!!!

It may be the coldest night we have all year here in South Florida, but I've set this up out on my porch. We will see how it goes in the morning.

I also have a Chromeboook that I tried to evict ants from by putting peppermint oil on a paper towel and sitting the computer on top of it. Sort of worked, but not completely. I wll use this on it as well.

Once again, thank you for the knder, gentler means of ant removal. I will update soon.

Thilanka on January 16, 2015:

Thanks for the tip.

Fertile Forest (author) from Sydney, Australia on December 14, 2014:

Thank you cren40, you are a gentleman/woman and a scholar.

cren4o on December 14, 2014:

Zoe, to recap the strategy: Ants will not nest or group in a location having only one pathway to get in and out. If there is not a 2nd pathway to use as an escape route in case the first route is blocked, they will leave before they become trapped. By eliminating all routes of escape except the one narrow bridge, they will leave as soon as their "scouts" discover the danger.

Fertile Forest (author) from Sydney, Australia on December 13, 2014:

Use one spoon/stick so there is only one safe way in or out of the laptop.

Zoe on December 13, 2014:

Hi. So how many spoons or sticks am I supposed to place for the ants to get out? I'm kinda confused when i read " One trail over water is not acceptable and they will not use it to return. " . Thanks! :)

Fertile Forest (author) from Sydney, Australia on December 04, 2014:

Good luck to you.

Jack on December 04, 2014:

Hey I read your post and I'm glad another aussie thought of this great idea. I have a brand new laptop and ants have moved in I think because it has been raining then humid in brisbane. oh well I hope it works for me too. thanks :)

Fertile Forest (author) from Sydney, Australia on December 04, 2014:

Stapler ants are bad for business.

Ree on December 03, 2014:

I live in the tropics and DO not eat near my computer.. ants be crazy and just like making nests in random places.!! Had to wash my stapler this morning due to ants nesting! No Kidding!

Fertile Forest (author) from Sydney, Australia on November 26, 2014:

If there are ants in your laptop there are ants in and around your house. Normally you and the ants live happily together without being aware of one another. Killing the ants in you laptop will not do anything to reduce the local or indeed global ant population. Let them leave. Other areas of your home can be ant managed by not leaving food scraps about. They are unlikely to move into your sock drawer.

faith on November 26, 2014:

If they crawl out using the bridge , wont they move to another part of our house to create their nest? Is there a way we can kill them when they leave the laptop? Thanks so much!

Fertile Forest (author) from Sydney, Australia on September 30, 2014:

Either follow the instructions above or do something else. You can't do both.

King on September 30, 2014:

Alright. I think ill just clean it first to make sure that food is not the reason ants are there. Will alcohol work or what?

Fertile Forest (author) from Sydney, Australia on September 30, 2014:

Chill out King. Remember this magic phrase with three letters, T T T.

Things Take Time.

Leave it overnight.

King on September 30, 2014:

i tried it but after a few hours ants are crawling in and out of the spoon. is that normal? im scared of leaving it overnight because i think more would come. help pls

Kay on September 08, 2014:

i will try it today

Vinod on September 08, 2014:

Thanks for envoirment friendly solution - need to check if this works one of these days

ninjad on September 04, 2014:

this solution really did work. Amazing. Now i'm a believer.

it redeemed my fury towards those ants. And got to know a little more about them.

Siempre on September 04, 2014:

I am a missionary in the Dominican Republic. I panicked today when I picked up my poor mac book and ants were swarming on it! Thank you for the advice! I'll def try it!

Vida on August 23, 2014:

Tried this last night, though I didn't put a stick I just let them drown (evil laugh). Surprised that it actually works, nice idea ;) But there are still a few of them crawling but not as many as before. Thanks again :)

Fertile Forest (author) from Sydney, Australia on August 17, 2014:

You need to design a setup where your laptop sits on four little feet which sit in water. Then an external keyboard and mouse which you unplug when you are not using it, Bluetooth wireless ones would do the trick. Each foot (thimbles?) could sit in a separate dish.

Sanju on August 16, 2014:

Ants in Laptop is common problem,especially in the hot region. I've noticed that ants usually be busy in the hot summer season and they tend to take full rest in the entire Winter.

The above method seems to be effective but it's not the permanent solution.I live in terai region where most of the months have the hot climate and eventually the problem of Ant is inevitable.So,i need the permanent solution. I have to follow the above methods time after time as the ants appear after few days of gap in my laptop.please any one help with permanent solution.

Fertile Forest (author) from Sydney, Australia on August 15, 2014:

Thanks CJ.

Hope it worked belladonna.

Thank you Anushka, looks like you followed the instructions really well.

Anushka S on August 14, 2014:

Hi Fertile Forest,

Thank you so much for this suggestion. It really worked for me. I put my laptop on a tray as you have mentioned. I went for some shopping. I came back after 5 hours and amazingly all the ants just vanished. I WOULD LIKE TO TELL EVERY ONE READING THIS POST... MAN THIS REALLY WORKS.... Must give it a try, after-all it is a harmless method, no damage to your laptop....Thanks once again for this suggestion.....

belladona on August 11, 2014:

Thank-you, I thought I was the only one on earth with this problem. I will be giving this a shot as soon as I finish this comment. My other solution was putting my laptop in the freezer, but wasn't sure if that could harm it. I have no ants anywhere in/around my home, it's so strange that they found their way to my laptop. I've used the keyboard spray cleaner, which did slow them down for a day or so, but then they returned. Thanks again.

CJ on August 07, 2014:

Read BLA's post again after your last comment..I don't think he said anything about poisoning the ants, just repelling them.... they were merely forced oit of their home. Might have left their eggs in panic though. :p

Stumbled upon your page when I was actually looking for a way to rid my rented apartment of house ants that bite. They're tiny and annoying and smell of formaldehyde when you squish them. I've located a tiny nest in the drawer I barely touched for about a year. But they are still aroumd in other parts of the house. Quite desperate because I dont have much to hire an exterminator and my landlady wont give a rats ass about it.

Fertile Forest (author) from Sydney, Australia on July 22, 2014:

Thank you for recounting your ant killing poison rampage. Maybe next you'll try the method described on this page?

B L A on July 22, 2014:

I wiped down my laptop with the original version of skin so soft bath oil that was found to be a bug repellant years ago by the US army. I still use it for bug repellant on my skin to this day but I have also found it to kill bird mites in my bedroom and yes my bed and now I have found them to run the ants out. I soaked paper towels with the oil and wiped it all over my laptop then I put the paper towels under the lap top and as they crawled out I squished some and just let others crawl away outside at the picnic table. I saw at least a hundred flee my lap top.

Fertile Forest (author) from Sydney, Australia on July 20, 2014:


Two things.

1) Are you sure you followed the instructions? Did you leave it overnight?

2) If you are dealing with two kinds of ants in your laptop there may be another reason for their presence, such as food.

vjw on July 20, 2014:

this method is actually mad!!!! i did this.. There were only red ants in my laptop. so i followed ur method and kept it for 12 hours. Ants were not gone and i found hundreds of black ants in my laptop.. this is not a successful method.. i had to open up my laptop and remove them..

Hola_Hola on July 17, 2014:

Excellent solution !! Will try it out !

Anne on July 16, 2014:

It's the next morning after I made my set up- so far no ants, but then again I've only used my laptop for ten minutes. I'll keep an update on how it goes!

Fertile Forest (author) from Sydney, Australia on June 25, 2014:

I really can't say for sure but the point of the setup is to make the laptop an unsuitable home for them. Even a few may be the vanguard of the thousands. I think they are gone.

Nicole on June 25, 2014:

Sorry to be such a trouble with all these questions! Also I realize I wasn't very clear so:

Yesterday I found some ants crawling on my laptop/ crawling out of the keyboard and USB port. I killed all those that I saw and started to panic. Then I came across your page and set up everything.

Immediately after setting up there were no visible ants.About 10 minutes after setting up, I noticed that there were two ants crawling around but I left them alone to cross the spoon bridge. That was late afternoon yesterday.

All of last night and today I have not observed any ants. I wanted to ask if this absence was due to 1) the fact that they have all left or 2) the fact that they are hiding.

Yup I hope this is clearer, thank you for all your help!!!

Fertile Forest (author) from Sydney, Australia on June 24, 2014:

Not sure exactly what you're asking but my guess is that if you only see two ants the others have left. It seems to work best overnight, something to do with their day/night cycle. A couple of confused ants wandering about is not a huge concern. The idea is to utilise their natural behaviours so killing them may interfere with what would otherwise be an average any day and they may act differently and not leave in an orderly fashion.

Hi, thank you so much for posting this solution here.

I just found ants crawling out from my keyboard. I don't eat in front of my computer, but recently there was an any infestation in my room and I guess that's how they got in. I've set up the moat and the bridge like you asked, but I don't see any ants coming out. Guess we will have to wait and see. I really hope it works!

Nalia, I assume you mean All in One?

Anyhow, as you say, as long as you can place it over water with only one exit they should leave.

If only it was my laptop that was infested with ants. My AIO has ants walking around behind the glass screen and im going insane. I'll have to try this method with a few tweaks to make sure my unit doesnt fall over.

Excellent Ruthie, no shame in laptop ants, it's not food they are after.

Cheers and good luck.

I felt a little silly searching for a solution laptop ants, figuring that very few people experience this problem. However, I am happy I'm not the only one! Thank you for this -- I am most definitely going to try this tonight! :)
