Ants in the mailbox

I have been getting my mail with ants. Little black yucky ants crawling all over my mail. And it was frustrating me to no ends when the mail man would put the mail in the back of the mailbox... where the ants were prolific. Well, today I had it with the ants. They were getting out of control. They had created little piles of ant baby eggs all along the side of the mailbox. It was disgusting and something had to be done. So, I went to the old internet to find out what people do about such a problem. The one solution that seemed the easiest (because I had the necessary ingredients) was baking soda. So I went to my fridge and pulled out the box of baking soda that had been in there for what I am sure was longer than a month and took it out to the mailbox. I poured baking soda everywhere inside that mailbox and the ants went running as fast as they could! It was interesting to watch them try to run to the ceiling (some of them succeeded) as most of them fell back down into the baking soda.  I waited until the ants had cleared out for the most part and then poured water into the mailbox to wash the rest out. The true test will be if there are any left tomorrow. I am hoping this solved the problem. But when ants are concerned there are no guarantees... those buggers work non stop until they die. But I am hoping that when I go to get my mail tomorrow all I will pull out of there will be bills... gosh.. who wishes that? ;)
