STOP! If you had these critters in your room, they will migrate, nearly everywhere. If you use a vacuum for cleanup, the micro dust that blows through the filter media will land everywhere. This Dander can be a problem for some people. An answer to this problem is to tape a black sump pump hose to the outlet of the vacuum and put it outside, so when operated, all the exhaust air is eliminated from the room. Damp or sponge mopping of floors will get everything but the crevices, and normal house cleaning agents are practical in this use, with a dash of chlorine based anything in the surfactant, (soap base) will wet down the little cronies and go a long way to defeating them. You do not have to use chemical killers to remove your doubts. Without food or a safe haven they will not last long.
For the cost, disposal is probably easiest, for safty and peace of mind, even tho it can still be fed off.
