About 17 years, Permatox and Theresa have been our exterminator. Always get a call the day before she will be at my home. Theresa is very knowledge anytime I have question about a bug. She's extra helpful with providing devices that can assist the removal of field mice etc outside, without harm to my dog. I have never had any bugs inside my home for 17 yrs, thanks to Permatox and Theresa.
