I am a property manager and I highly recommend ProChem. We used to use adifferent cmpany and still had problems with roaches, could never really get rid of bed bugs. Then, a couple of years ago, we switched to ProChem. We are so happy with the service. No more roaches. Occasionally someone may bring them in when they move in, but the problem is always eradicated immediately. ProChem uses heat treatments for bed bugs instead of spraying. This actually works. The residents don't have to throw away all their stuff and it works with one treatment. Instead of not working with four... If you are a property manger or even a homeowner, I highly suggest you get in touch with ProChem. You will not be disappointed.
