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.
They respond quickly and their technician is always so polite and friendly, while the service is effective against pests.
Ray is great. He listens to my concerns then explains how he will treat the issues. He used little capsules and strong roach poison. I can ask him questions about the process and he takes time to explain how roaches reproduce and how the ingredients he puts down each will contribute to the process of eliminating the pests. He is very kind and polite.
Chem-Wise is very responsive to any pest issue we have had. They are able to fit us into their schedule quickly and their technicians are knowledgeable, confident, and friendly. We highly recommend.
Excellent technician. Customer focused and detail orientated.
We've been using Chem-Wise for a many years now and they have done a great job keeping our house pest free. They stopped the mouse issue we were having and the tri annual service keeps the ants out too. The technicians that come out are friendly and they do a thorough job. I would highly recommend Chem-Wise.
Was very pleased with Michael. He rang the doorbell and introduced himself before starting. Did all around the house an5 and bushes. Did a great job. Thank you.

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.

Davis was great at keeping me informed of his schedule on the day of service so that I knew within 5 minutes of his exact arrival time.

Our technician is great! Danny always checks in to see if we have areas of concern before he treats our property. Usually we don’t, but recently we’ve had these minute, red spiders all over our patio and Firepit area. Danny explained that these are clover mites, and he took extra time and care to treat the entire…
We have not had any problems since Michael started to take care of our insect and rodent issues. He is punctual, professional and friendly...highly recommend Chem-Wise and especially Michael!!!!

We have been Chemwise customers since we moved to Wheaton 7 years ago, they have always been responsive and professional. Our technician Jim has the most outstanding customer service and goes above and beyond to help troubleshoot bug and rodent issues as well as provide education. We highly recommend their services.
Typically the treatments have been good. Today we were not home during the treatment therefore can’t comment on the service. I did notice that the windows do not show water tracks which typically happens after treatment for the ladybug infestation that does occur here. Only Time will tell but we sure hope the ladybug issue will be resolved!
Davis always does a great job and is very knowledgeable. He always explains what services he is performing and always asks if there are any concerns or if we have anything specific we need him to look at.
Technician Brian Reyes is knowledgeable, professional, efficient, communicates well, and is customer service oriented. Chem-Wise is my choice for pest control because of Brian’s expertise.
Rigo and Chem Wise are the best! Took care if our Wasp/hornet problem so quickly. Thank you!@
Great service
A few years ago, I contacted Chem-Wise for an ant issue. I've started and kept their seasonal service since. I recently added the wasp service and it has been worth it. I have and would continue to recommend their services. Their service is effective and thorough. They are easy to work with and have a great staff.…

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…
Very professional, courteous and attention to work. Great job! Very satisfied!
Bruno let me know when he got to my home and why he was there. Very nice guy.
The technician serviced the house next store for Boxelder bugs instead of our house, even though their house didn’t have a Boxelder bug problem, and then billed me. I’m expecting them to correct their mistake.
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.
We’ve had this service for a couple of years. Worth the few pennies we pay. Courteous, helpful, knowledgeable technicians. Thanks.
Matt Denny did an outstanding job servicing my home. He was very professional and had great attention to detail.
We have relied on Chemwise for more than 20 years to keep our home free of pests and wasps. Their techs are always professional and, if the service is on the perimeter of the house only, I often don’t even know that they were here. Correction: I do know they were here because my back deck looks tidier because they…
As a past customer, I knew who to call when we discovered a new bee problem - in a outside wall. I called up and within 1 day they sent a technician (they could have come the day I called but I had to work). Professional, thorough and very knowledgeable - this is how I describe Charles and the company.
We have been using Chem-Wise for over twenty years. Their friendly responsive nature and the quality of their work are beyond question. We recommend whenever we can.

We love Matt Denny! He’s very friendly, always on time and goes above and beyond to make sure we don’t have any little unwanted critters around;)
Davis is our family’s technician. He’s come out to our home three times now and each time, he was kind and quick! He also took the time today to explain some of the critters that have been giving me a headache with all the rain we’ve had in most recent weeks. We look forward to continuing our services.
Super nice technician today! We've used them for the last 5 years and have been very happy with the service. They will come back right away if you have any problems.
Davis was great! Thank you!

Update 6/14/2023: our most recent technician, Josh, has just been incredible! He is very thorough and wants to help us fix our mice issue. He's been out several times and goes the extra mile each time, even offering for a follow-up to come out and help get under our deck to find any openings. Chem-wise is VERY lucky…
Josh is great! He is very thorough, attention to detail and works hard to make sure all concerns are addressed. He deserves a bonus!
For the first time ever we were seeing cockroaches. I immediately called my pest control guy. 2 weeks later and we saw zero change. In fact, we had more. Chem-Wise came in and had us all fixed up in 2 weeks. GONE! I have switched to Chem-Wise now for our monthly plan.
Jim is always friendly and always takes an interest in what is going on. Anytime I call he comes out and explains whatever needs to be. Thanks Jim!

Jim was here with in 30 minutes or less! He is always so nice and checks all areas of the store.
We’ve been using Chem-Wise since 2020 when we moved into our new home and they’ve been fantastic from day 1.

Jose was professional, knowledgeable and thorough overall with his work around the outside of our house and the basement. Very impressed with his work and recommended follow-up for protecting our house against mice. Thank you.
Very satisfied. I have basically had no insects in or around my house since I started using Chem-Wise. No longer do I have to deal with boxelder bugs. I started the mosquito control this summer and was very happy. No mosquito bites.
Chem wise is the best. Mike is very professional.

We have used this firm for many years and always find they stand behind their service. Great company to work with.
We have used Chemwise for several years and have loved our experiences with them. We use their general pest control service, which has eliminated issues we used to have with ants. More importantly, we have used Chemwise to deal with a nagging issue of mice in our basement. Chemwise has been extremely professional…
