5 Star Review for Harper Pest Control

I met Thomas P. in my Orange County Neighborhood and after learning about his Harper Pest Control company, we decided to switch from Orkin and give them a try. The rates are more affordable than I was previously paying with my former pest control service. We are on a bi-monthly service plan and if we have any issues in between services, they will come and spray at no additional cost. It is mosquito season and over the past couple of days I've noticed an increase in mosquitos. I emailed Thomas late last night and he called me back within minutes and scheduled a service call for early the next morning. He arrived on time and sprayed inside and outside of our house. I was very pleased with this excellent level of customer service.

5 Star Review for Harper Pest Control

My family just moved to Mission Viejo in the Ivey Ranch area and we were overrun by ants and spiders. At my old home I used Orkin for years, and they were great, but EXPENSIVE. These guys were out canvassing the neighborhood for new business and I liked both the pitch and price point so I went for it. They completed their first service and for a week we're fire ants free. Terrific. Keep it going...

Amazing family run business! We initially were looking for an ant exterminator in orange county and found Harper. They are very responsive, reliable, and quick to solve pest problems. We have a monthly service scheduled and have had no bug issues since we started using Harper Pest Control! Highly recommend giving them a call for all your pest needs.

Fantastic service, very knowledgeable and extremely professional. We have been using Harper Pest Control for 3 months and are so pleased with their service that we recommend them to all of our friends! I love that every visit I'm asked "what can I do better, have you had any issues"?  The "Mom and Pop" feeling of this company really sells itself.
