That's an easy one. Finding 100 worms in your toilet.
Although Japanese beetles do munch on my plants from time to time, especially after rain washes all the sevin off my okra, I am thankful we don't have many. They were really thick in this general area about 20 years ago, to the point that everyone set up those traps that were bags on a wire hanger and they'd just fly down in by the thousands and get stuck then rot all day in the summer sun. Stunk like crazy but I think some of the smell was also the bait they used to lure them in.
