What customers said about bug & insect extermination
Scotty's Pest ControlVery professional and quick to response to my calls when I made the call to have them come spray our house we just moved into for bugs! Thank you for the great service! We will be calling again!
Plunkett's Pest ControlAs first-time homeowners, finding mice in our house was the last thing we wanted to deal with. Dylan came out right away, put together a clear plan to take care of the issue, and helped us feel confident that future problems could be prevented. Highly recommend!
Scotty's Pest ControlI've had Hunter and Albert with Scotty's Pest Control out a couple times so far and the service has been excellent. On-time, thorough, and took extra time to address my specific pest concerns. Very happy with their work. I also like the idea that this is a small local business vested in keeping their clients happy.
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.
Plunkett's Pest ControlMauricio was very professional and personable. New as a service person to our home, he was willing to meet our 3 barking dogs, but we decided to save that meeting for next time! Mauricio respected my need for an expedient visit and still provided perfect service, just as expected. Thank you!!
Scotty's Pest ControlThe guys with Scotty's Pest Control are wonderful! Knowledgeable, timely, friendly and they get the job done! Highly recommend!!
