Pratt has been servicing our house and rentals for around five years. We used to have a different company attempt to do what Pratt does but we still had problems. When we contacted Pratt, they identified problem areas (which the other company didn't seem to notice) and took steps exclude the intrusions. They are not afraid of inspecting under the house (which they do on at least a yearly basis) and have a regular scheduled service for the problems you can expect for that time of year. What really impresses me is that they are a can do type of people. You see mice droppings, ants, spiders, even woodpeckers - give them a call and they'll have a solution, not next week or month, but right away. I feel fortunate I have them on my side!
