What customers said about cockroach extermination
Scotty's Pest ControlListened to my concerns, took the time to get to places that I could not reach. Extremely friendly and went out of the way to spray our apartment stairs.
Plunkett's Pest ControlOur exterminator (Derek) always listens to our concerns. He always figures out the best solution, ensuring our dog is never harmed by any chemicals. I highly recommend Plunkett’s Pest Control.
Scotty's Pest ControlFast, friendly, efficient service. I’ve had other pest control places spray before while renting and they use stuff that I usually have to wipe a film of away after a month or so, and having animals that frustrates me, but when buying my first home, I used Scotty’s pest control and didn’t have to worry about any of that.
