How do I get rid of roaches coming out of my shower drain?

Question by diane z: How do I get rid of roaches coming out of my shower drain?
Okay, this is gross, but at least once or twice a week, a darn roach comes up out of my shower drain. I live near a farm and have been told that the land my house is built on used to be farm land and that’s why. I’m in a one-story house & presume that if I was in a 2 story, I wouldn’t have this problem. I have no idea how to get rid of them. If I put a chemical in the drain, it’ll just wash away. It’s an enclosed shower and there are no other entry/exit points. Help!

Pour a foam down the drain. There’s some kind of drainpipe cleaner that is split into two chemicals in the bottle, but mixes when you pour it out, and when it mixes it foams up. Stuff like that is really toxic. Pour the whole bottle in (which you are supposed to do) and let it sit there for 24 hours.
