in every place i have ever lived these "million leggers" (i thought i made that up as a kid) have been present. i find that they come out more during the warmer months. i am in ohio currently and it has been very hot and humid recently, and our a/c has been kept pretty low. i think these bugs are drawn to moisture because they seem to reside mostly in our damp basement. often times i find several of them in my toilet in the morning, and let me tell you, that is not what i want to see first thing in the morning. i would be totally cool with them if they stayed in the basement, i'd even feed them if they wanted. but when you are watching t.v. and one darts across the wall or floor it freaks you out. it has happened to me dozens and dozens of times, but it still freaks me out. i also scream like a little girl while i try to kill them. its best not to chase them, you won't catch them. you have to ignore them and wait until they stop moving, then you have to tip-toe over to them and get really close, then wham! you squish them. i find charmin extra soft to be most effective. never, ever use something thick like a paper towel or newspaper. you won't be able to squish them and they will fall out of the towel and disappear into the night. good hunting
