Pest Control Reviews in Carol Stream, IL (Updated June 2026)

Extremely disappointed in kn y'a this is the first time they have ever refused to do the interior of the house, where they've always done the interior of the house. All's attack would say is that he'll only do around the windows. The door trims, and if the basement was unfinished, before they used to do around the baseboards in between the stove, behind the refrigerator under the frigator and basically a complete great job in the interior to where now they do hardly anything in the interior. As far as the exterior goes, you could see several areas that they did not do this time.So even the exterior they did in an extremely poor and unfinished manner. They're very firm with not doing the job correctly. Anymore so I will no longer be using them. So please be aware that they do not do a good job anymore. They are not the same company that had a 4 and a 1 to a 5 star rating. This policy apparently has been inset forever.Even though we've used them for years, and this is the first time that anybody has ever brought these new conditions to our attention. If this is the way they're gonna complete your house service, i'm sure in the future the ratings are going to drop drastically

Angel came out 2 weeks ago and spent time identifying the mice problem and solutions to keep them out. I felt much better after he left and assured me he would be back in 2 weeks to finish up with the solution. He promptly arrived today and did just as he said he would. I now have no mice and he sealed up all outside openings to prevent visitation into my home. Angel answered all my questions and is very knowledgeable along with solutions. Outstanding service as I had another service for a year and they definitely did not stand up anywhere near to Chem Wise. Chem Wise goes over and beyond expectations. They definitely walk their talk; I would highly recommend them for any types of pest control. Great great job Angel!

Since starting with Chem-Wise, we have not had any troubles with pests in our home. If we have any issues in between treatments (like ants after a lot of rain) they come out right away. We bought an investment property that had been neglected for years. We had them out right away!

I have been using Chem-Wise for many years and they have always been responsive and courteous. More importantly, they have always removed any pests that were not where they were supposed to be. I would recommend Chem-Wise for all your pest control needs. Keep up the good work! Thank you, Dave

Employees are always courteous, kind, friendly and professional. When making an appointment to come out, they come out quick and around my work schedule. I have used this company for over 10 years, would never use anyone else and I continue recommending them to everyone.
