When we bought our home it had the tubes in the wall for pest defense. We thought it was a good concept since everyone knows that bugs live in the walls. Our initial service was a reasonable price of approx $45 but after that it was $74 every 2 months. It might not seem like much, but for spraying chemicals into the walls that seemed a bit pricey to me. We decided to break our contract and go with another company that charges much less and sprays everywhere inside and outside my home.
