These are one of the favorite hunting conquests for my two cats. They are fast and change directions quickly and can fly. They are tough to catch to throw back outside, but not as fun as a cicada that is flying around and your cat(s) are jumping off of the furniture trying to catch them again. There are times where the cat and I are trying to catch the waterbug before it gets somewhere hard to get, but for very different reasons.
Neighbors decided they were tired of tenants and roach problems so they removed the kitchen from their rented apartment.
Roach problem went away for them and me.
I will randomly get a few waterbugs (https://en.wikipedia.org/wiki/Oriental_cockroach) which are alarming but it's usually when temps are dramatically changing.
