Ya .. most pests are controlable .. those bed bugs are very nasty, v\ery dificult to detect untill the are biting people, and almost impossible to get rid of by consumer means. Got infested once by a vagabond type man who was not clean and had a infested sleeping bag. This is one reason why a lot of hostels have a rule about usuing sleeping bags. We now only allow sleeping bags for the Boy Scouts and other youth groups that I am relatively certain are using their sleeping bags on a regular basis.
The bugs, we had an pest control company come in, that way I get a garauntee of ressults. But took two trips and screwed up business for two months, plus the loss or a good group that just happened to arrive the weekend after this guy.
