Now that all the stuff is out of the bedroom, it’s time to treat the room itself. The first step is to vacuum every surface in the room, the baseboards, all the furniture, the mattress, box spring, bed frame, everything. Use a small wand to get into all the corners and crevices.
When you finish, throw out the vacuum bag to avoid spreading the bugs. If you use a shop vacuum or bagless vacuum, dump the contents you’ve collected into a bag, tie it up, and throw it out. And treat the filter and the inside of the canister with contact spray insecticide.
Flat surfaces like walls and dresser tops can be wiped with alcohol. Wipe a small inconspicuous area first to see if the alcohol will damage the paint or finish.
