Ant Murderer

I feel really bad... I murdered a bunch of baby ants. Apparantly a mama ant laid eggs in my mailbox because when I went to put a letter in this morning... the inside of the mailbox was swarming with tiny baby ants! There was this spider web looking stuff, which is where I'm guessing the eggs were. I hate ants... really hate ants. But these were baby ants and I feel awful... but I had to spray them... or my mail would be crawling with ants! So I am now an ant murderer. :(
