If you cannot afford to hire someone to prep your apartment/home for bed bug treatment and you are finding volunteers to help you prep your apartment, yet don’t want them to bring them back in your own homes, here is a suggestion given by our friends from Quest Pest Control:  Ocean State Joblot sells these one-piece white zip-up HVAC coveralls  at $4.00 apiece. Make sure you cover the bottom of the legs with your socks so bed bugs don’t crawl up your legs inside the pants.  Also wear footies to cover your shoes.
After the preparation is executed, discard the overalls in a secured plastic bag and throw them in the trashcan outside of the house/apartment.
