We have Bed Bug issues. What now?

Well you can sleep over a friends house or even rent a room in a motel/hotel it would be a good two day relaxing session and you wouldn't have to deal with the nuisance of pest control process. I suggest you throw anything and everything that these little pests could be hiding in. Throw out your mattress move everything from its spot and check under everything for them. The exterminator should have already mentioned this and should have taken care of the problem, and don't know why they came back after he left. Anyway best of luck, and hope anything i said helped.
