TITLE: TIFU by thinking I was an ant overlord.
POST: So, I'm very lazy when it comes to cleaning my room and about 2 weeks ago, I notice a bunch of ants have started to make a home somewhere in the walls. They were very small ants, and apart from being bitten once in a while (not that painful), I didn't mind them at all for the fact that every time I dropped crumbs and other food stuff I couldn't be bothered to clean up, I noticed that given a bit of time, my ants would clean it up for me. SWEET!

I had a whole army of ants at my disposal and they were doign a great job of keeping my room clean. I would drop crumbs all over the place after snacking in front of my computer, go to bed, and wake up with them all gone. I was pretty satisfied with their work, and made no effort to get rid of them, they became my cleaning minions. 

Several days ago, I started noticing that they had started working on cleaning my keyboard, ants were streaming in and out from under the keys (I have a mechanical keyboard), and I was really happy about it. It's going to be spotless under there! I paid no attention to them, and let them carry on with the good work.

This went on for a while, and my keyboard must of been really dirty because they continued working on it not stop. The fuckup happened today when one my keys got kind of stuck, and when I pressed it, a swarm of ants came out from underneath. I pulled off the key and looked underneath to find that in fact, they hadn't been cleaning my keyboard by hauling stuff out of there, they were using it to build a freaking nest! It was chock full of ants and saw-dust looking debris tightly packed into every crevice. I spent half the day taking my keyboard apart and cleaning it, dispersing a swarm of several hundred ants that made it their home. Luckily, keyboard still works fine.
TL;DR: 
Thought I was pretty clever by using ants to clean my room and keyboard for me. Turns out they were using my keyboard as their storage place and hauling all the crap they found into it.
