We've been using Masters Pest Control for several years much to the dismay of the mice we USED to have. We haven't seen a mouse in at least two years. The technicians who visit us monthly are knowledgeable and determined people, they go everywhere in our house from under-the-roof to under-the-ground. They also happened to be nice guys who have answered every question and concern we've had! The office staff are also pretty great people - easy to work with and very accommodating, they make things work.
