HELP! How do I get rid of these Palmetto Bugs?

You have seen the problem. There is no way to get rid of them if they keep finding a way in. If there weren't the drought conditions, you could exterminate them in the house. But you obviously can't go outside and kill them all. There is no repellent that I know of. There was a few years ago an electronic repellent you could plug into the wall. Maybe it still is sold online somewhere. Don't know whether it works or not.
