After experiencing a worsening infestation of carpentar ants each spring for 4 years, we decided to call Cain Pest Control 2 years ago. Since then, they have sprayed the house twice and there are basically no ants to be seen since then. Carlo was very friendly. He explained the entire process to us before doing the work. He also used minimum chemicals in the house and went as far as to remove some of the baseboards and leave ant powder inside the walls to avoid using more pesticides than necessary. We would definitely recommend him to anyone with a pest problem.
