Bedbugs can be a tough pest to prevent. Namely because these little insects are notorious hitch hikers, and you could completely seal all possible ways for the bedbug to come from the infested neighbor and still bring some home on your belongings from the movies, the mall or your place of employment. Having said that, you should still do all that you can to prevent having bedbugs come over from the neighbor. You should use caulk to seal any cracks or crevice around the baseboards, window frames, door frames, and around places where vents, cables, pipes or wires come through the wall. You can apply a dust such as Cimexa dust into wall voids, electrical outlets, and switch plates. This will help kill any bedbugs that make their way through the walls. We also recommend thoroughly inspecting your mattress and headboards and bed frame frequently for any signs of bedbugs.
