We just moved into a new house which was full of cockroaches. We tried killing them, using a spray from homedepot which was a failure. I than called PESTOKILL. Next day VANCE was here, all quiped with his high tech machines. Within 2 days after the treatment all cockroaches were dead. It has been a month now and i havent seen any cockroach in my house. Vance is very PROFESSIONAL.
