I have ants in my room I know where they came from and why?

Question

I am a pretty irresponsible teen. Its the summer vacation and when I brought my bag home, there were 2 sandwiches in the bag. I left it there for 2 weeks and my parents aren't home so I decided to clean it up. Not to anyones surprise, ants are in my room. I killed them all, even the little eggs the b******s left to a couple different spots in the crack in my wall. Well this crack is where the nest is, I am watching them come in and out. I threw out everything that had the ants in there. I am going to tell my parents but first I want to know what to do before telling them. I hope that knowing the reason and where the nest is helps out A LOT. Thanks for your time I am probably going to be subject to a lot of scrutiny for this

Answer 1

covering the crack with tape ,will not help one bit

in the first place never leave food around for mice and ants ,and they will have less reason to be there.

for the ants make a big pot with a brew made from cigarette buts ,leave it to soak for a few days ,(the longer the stronger)

and spray this in to the hole ,

much better than chemicals which can harm you as well.

Answer 2

theres this thing called cigarette stew. you leave a bunch of butts soaking in a pot for a few days. then put it in a regular spray bottle and spray it into the nest
