I think I'd rather take a chance with Black Widows rather than Brown Recluses. We are covered up with Black Widows here. My husband captured around 50 of them when we removed the rock border from around two Maple trees. I have a watergarden and they lurk in the rocks. I can't spray them in fear of poisoning my fish. He feeds them to the fish. :-) They like them. Few people seem to be bitten by the Black Widows but Brown Recluse bites are very common in this area.
Brown Recluse bites are nasty...
