We have bugs. We've had them since we moved in and they are cyclical. First come the crickets, then the pill bugs, then the millipedes. Now, before you start thinking we live in a dive, our house is actually very nice and the previous owners kept it meticulous, but a few days after we moved in we noticed that there were crickets in the (finished) basement. Not just the ones you hear either. We SEE them - daily! They come around June and stay until mid- to late July. Then they go away, who knows where, and along come the pill bugs. These little guys are the least offensive of the bunch. I usually don't kill them, I just relocate them outside. They're cute.
But then comes September, and the not-so-cute millipedes invade. At any given time, you can find a few crawling across the basement floor or maybe in the basement shower (the kids really like that!). Sometimes their dead, just curled up in a little ball, but more often than not, they are crawling, EWW gross! Now doesn't that just make you want to come and visit us :) The ones crawling across the basement floor are nothing compared to the piles of hundreds of them outside our front door!
Actually, when we had a pet turtle one summer, the crickets came in really handy! It's great fun to watch a turtle eat a cricket :)
