They are a good company. We got bed bugs from used books in the library. On a Saturday morning we realized what the problem was and we were flying out to go stay with relatives the next Saturday. They were able to respond in like two days. They heat up the whole house to like 125 degrees for like 5 hours. So its a big ordeal. The home power lines can't handle it so they used transformers and generators. They took care of the problem.
