I bought a house back in July and it was filled with German Roaches.
Did what was needed to rid the place of them. there is one room that I think where it must have been infested with them. It has a really awful smell and after talking with a few people they said nothing could be done other than to rip out the and put up new ones. So my question is what is the best way to remove old Drywall and also the breaker box in that room is a mess is it just a matter of buying a new one and poping it in?
