This was the second time I have used Chem-Wise to address a problem of extensive damage caused by carpenter ants in two portions of my garage. I am very pleased with the knowledgeable technicians and highly recommend Chem-Wise for problem pests.

Donald is the best! I have had three different pest control companies over the last several years. None did the job anywhere close to as well as Chem Wise and your technician Donald. I am a huge fan of Chem Wise and especially Donald. He is the best!

I don't usually respond to requests of this nature, however they were exceptional in their service. We had a very large hornets nest. They came when they promised and treated it with utmost professionalism. A return visit was required to remove the hive when it became inactive. We were very pleased with our experience and will definitely take advantage of their services next season!!!

Always on time, able to schedule quickly, and your technicians resolve the problem, whether it be ants or mice. I will continue to use you, and have recommended your service to friends. Also affordable.

I have been using ChemWise Pest Control for years. Initially for a mouse problem I had which happily is now under control, and most recently for a hornet nest I had in the front of my house. They have successfully rid my house and perimeter of all the pests!!

They called prior to arrival so we could secure our dog. They sprayed everything necessary and locked the gate to the yard when finished.

We've used your services for many years and have always been pleased with your technicians who demonstrate care, safety, thoroughness, and are happy to answer questions and explain the process of their work. I love also that you will come back out without additional cost if we continue to have pest issues, including bees/wasps/hornets if we've had that service. Thanks for the great work and company you run.

Donald checked with us first to see if we had any areas of concern, so we told him the spiders have been active this year and he sprayed the indoor bathrooms, our screened in porch and the areas outside as he usually does. He is so polite and would do whatever we wanted. I appreciate how polite he is and his eagerness to take care of any pest areas. He gets 5 stars from us again this time.

We used chemwise for control of ants. Ant season seemed to be more intense and longer this year due to wet weather. They treated both inside and outside and problem diminished. The tech was knowledgeable and provided detail explanation on treatment. They have a 90 day guarantee which we have not needed to use. They also did a wood eating formal pest inspection related to a sale of a house. The person who did inspection was knowledgeable and explained what they look for when doing these inspections.

The technician was very knowledgeable and courteous. This was a problem with yellow jackets. He treated the two areas and the yellow jackets were gone within a day.

The staff left our gate open after leaving and our dog got out.

I was called just prior to my appointment to let me know the arrival time. He treated for carpenter ants as well as the routine outside treatment around the house, although the hose didn't quite reach to the back of the house. He couldn't park in my driveway since it had been seal coated the day before. He did his best to treat the back area. He was very polite and explained how he was treating the ants. I'm happy with the results so far but will wait a couple more weeks to determine if the queen was eliminated and ants return.

The hornet infestation was eliminated. I was disappointed more of the nest debris was not cleaned off of the house.

Ball hornet nest was treated and everything was eracated. I want to give 4.5 stars just because there was no follow up on when the nest will be removed, I had to call the office to get a answer.

Went to and serviced wrong house. When another service rep came out, he sprayed over all the windows and now can't get off the film it left on the glass

We have used Chemwise for the past few years to control our summer and problem. They are always quick to respond and professional. We have had different technicians over the years and they are all respectful of the property and very friendly.

Very pleased with Michael and his professional attitude. The first visit was for ants in our house, and he took the time to explain everything and treated both the interior and exterior of our house. Ant problem was solved!! A great company to do business with. The follow-up treatment only had to be applied on the outside of the house. Great job!!

I called outside of my tri-annual service because I had seen 2 ear wigs in my bedroom. I was able to get an appointment within a week and haven't seen any since!
- Jennifer Cucinella

Frequently does not show up during their appointment time. They are not apologetic and it does not get fixed for the next time. The office staff may lie and make up some excuse and then offer another appointment on a different day. Service is good but it may take a few appointment times until they come to do the service.

Never had an ant issue since starting service. Thanks!

We’ve been customers of Chemwise for almost 15 years. We have had mice and wasp issues over the years and Chemwise has always delivered prompt service and has successfully eradicated our pest issues. Highly recommend!

Chem-Wise is the best. We've had their Tri-annual service for many years now and they always do a great job, actually does work and anytime we need anything extra such as ants in the house, they're easy to work with and abate the given issue. Definitely recommend for general pest control needs.

Treated my yard successfully for tickd last year. Got bit twice this year so had them come back this year. No problems since!

They do a great job and I especially recommend their wasp proofing, we had so many problems with hives and bees getting into my house and garage it was awful. Since I’ve had them spraying, not a problem at all.

I have had a nuisance problem with Cricket Mites. They refuse to give up. But Robert is determined to get rid of them. He, too, refuses to give up. I have had service 3 times because there seems to be a few stragglers on my window sills. Thank you, Robert for your determination! And I love Chemwise because I don’t have to worry about my dog!
