We've used Terminix ever since moving here in September 2012. We used them first in our rental and stuck with them when we purchased our home. They've been very easy to work with!
With our contract, we receive quarterly spraying. If we're not home, they spray the perimeter of the home and the backyard, and they'll come inside if we need them to when we are home. Also, we can call any time as needed for extra visits.
We rarely have any pest issues but occasionally we'll have some ants pop up in the downstairs bathroom and we're able to get a timely appointment to fix the problem. The phone operators are always pleasant.
Our service tech is always the same and we love him! He's great with our dog, sprays our garage and puts down sticky pads, and will get anywhere in the home where we have concerns.
I agree with another reviewer that Terminix is a bit annoying with their Termite protection sales. We just ignore it because the service we receive through our regular plan is excellent and no hassle.
