We have a place in ND and did that with some Salamanders that we would find in the basement. We noticed that the bugs in the basement (old farm house with rock and brick basement we use as a hunting camp). Now we just name them and tell them good job. Never have found a dead one so we think they migrate in during the summer then leave in the fall.We've always had a bunch of wolf spiders in the house, especially the basement. But a couple years ago I found a small desert lizard in the basement, then another one, and another one. I'd keep tossing them outside, but they keep coming back. In the last year, we haven't seen one spider in the house. I think I'm keeping the lizards, and told my daughter to take a couple back with her to Missouri this summer.
