Very professional, expedient, and knowledgeable. Enrique took the time to explain his approach to solving our issue and did a great job. Highly recommend Chem-Wise.

From office to service point they have a high quality customer orientation. They are friendly, courteous, true professionals and get things done right.
On time, thorough, professional. Knowledgeable and very polite.
I’m always happy with my triannual membership. It had made a huge impact eliminating pests indoors and the team is responsive and friendly. Enrique is an awesome technician. Thank you!
They respond quickly and their technician is always so polite and friendly, while the service is effective against pests.
Bruno was great and very courteous and professional. He was very knowledgeable and respected the property. He answered all my questions. Thanks, Bruno and keep up the great work!
I used Chem-wise when we first moved in to our home over ten years ago. I was worried about mice but we had spiders and ants. They were great, but another company offered the same service for less and I switched. After two years of being disappointed, I called up Chem-wise. I trust their technicians and customer…

Davis is always professional and through. When i need them to come back out there is no problem and great turn around. I have used this service for all different types of insects for years. I highly recommend them.
On time. Good Information received from Tech. Our problems with pests have been eliminated.
About 15 years ago, I had ants in the dog’s dish and webs on the chandeliers. Che-Wise was able to resolve those issues from the outside. The few times I have had to call them for indoor issues, they arrive promptly, are very courteous, and thorough. I highly recommend them!
Had with a new professional, and I am STILL just as thrilled with his service and professionalism. He really listened, cared, and made me feel very comfortable with my questions and even offered helpful tips!!’ love that I have the same tech assigned to me so he works with me and any issues I have. He is so…
I wanted to share my honest experience with Chem-Wise annual pest control service so other homeowners can make an informed decision. My last service visit was back in October 2025. The spring treatment, which should be completed by June 2 per their schedule, was never performed on time. As an auto-renewal customer,…

Davis is a great guy responsible, respectful person. Attention to detail is great. I am lucky to have him as my bug guy !!
I'm very impressed with the experience so far with Chem-Wise. The technician,Tim did a thorough job spraying around the house and bushes and even covered the inside of the window wells.

Charles does a GREAT JOB! He is very thorough and friendly. GIVE HIM A RAISE!!!

Jim came out to do our spring treatment. Every time he comes out, he always takes the extra step with customer service. He is very friendly and personable, and makes sure to ask about any issues we may have. He is also always willing to come back if we have any further issues that are not taken care of with our…
Below is the review I wrote a couple of years ago. I am adding, today, to say that we recently discovered we have voles and Chemwise was able to help! Two weeks ago, our technician, Danny, came and explained everything. He was back for a check-in today, and the treatment has been effective! Also, it's safe for my…
Customer service is the main mission for this company, it seems. I’ve never had a bad encounter with the office or the technician. They are flexible, accommodating, professional and aim to address any pest related problem. Matt, the technician, advised me on my chipmunk problem based on his experience. He was very…
I met Dan today our tech. He was super interested in my issues. He paid close attention and completed every task he thought was needed quickly and clean shoes covered and extremely well versed. I enjoyed speaking and dealing with Dan.
Our technician Brian was wonderful. He took the time to review our records and asked if our prior issue had been taken care of, explain the service being performed today and made sure the yard gate was closed so our dog did not get out after he left. We are very happy with Chemwise.
While Enrique's work is very thorough, there can be improvements on the office making the appointments. I was given an email reminding me of an appointment which I was not involved in the making. The reminder did not include a time.
The service tech Matt was outstanding.
Excellent work around the house and garage. He was very thorough.
Matt Denny did an outstanding job servicing my home. He was very professional and had great attention to detail.
Technicians are professional, quick response to questions and always prompt for appointments. Consistent.
