That must have been terrible to see that many ants in one place, especially in your bed. Many years ago I had ants in my kitchen just in one spot, but they went away and have not had any problems since. I don't like "creepy crawlers" of any kind. From time to time, especially in the summer, a cockroach will get in when you open the door. I do everything humanly possible to swat him, sometimes I miss. I do have the pest control that comes every two months so what I don't get they will. I also have what they call "IndianMoths", the pest control man told me that they don't eat clothes like other moths do, but they are a nuisance because they fly around, but are very small. The pest man puts these things around that hang up and they fly in there and get stuck. The only thing I can kill is a roach, a spider and the moths
