Oak Hills does a quarterly bug treatment for me. They spray inside and out once every three months. They are very thorough, and rarely do we have a problem with any bugs between treatments. If there ever are any problems they come out for free and respray. All of the technicians that have come to the house are very friendly and try to minimize the disruption to our day. You are given a 2 hour window in which they will show up, so you are not waiting around all day.
