At Patrick Exterminating we take the approach that most insects which cause a homeowner distress originate from the outside. Therefore, our household pest control concentrates more on exterior applications. By addressing the source of insects we can limit interior applications to an as needed only basis. Our customers prefer the idea that chemical applications inside their homes are not done just as a matter of routine. They also prefer the convenience of exterior treatments and appreciate not having their schedules interrupted. Our Bi-Monthly exterior service is fully guaranteed and in the event we do have to make an interior application there is no additional charge.
