Keeping a house clean?

Unless you are willing to clean it all the time, or get your roomies to do their part, you will always have roaches and gnats and probably rats. Personally, I'd start looking for another place. With all that would need to be done in such a nasty place you won't have much time for yourself, if you wanted to keep it clean. I couldn't live in a place with dog feces and urine all over the place, filth in every room and insect infestations. Might as well live in a barn. Just move. It will save you time in the long run.
