Our home has been treated by Thrasher for over a year and we've had an excellent experience with them. They are consistent, thorough, and their technicians do a great job in communicating when they are on their way and giving an update when they leave. We have worked with Miguel the most and recently with Eddie as well. We highly recommend them for mosquitos, roaches and all the creepy crawlers!Posted on Google![]()
