September heat increases mosquito activity across San Marcos fast. Standing water in yards gives them a place to breed. We treat your yard and reduce their numbers.

We called Thrasher to help with an ant problem, and we couldn’t be happier with the service. Eddie Amaya was extremely helpful, knowledgeable, thorough, polite, and professional. He took the time to answer all of our questions and made sure the job was done right. Within just a couple of days, the ants were completely gone! Thank you, Thrasher, and a special thank you to Eddie for the excellent service and a job well done. Highly recommended!Posted on Google![]()
