Steve, our technician, is punctual, professional and knowledgable.
Bruno, our technician brings great knowledge and exceptional service. We have had Chem-Wise for many years and have always been pleased with their results. From office to service point they have a high quality customer orientation. They are friendly, courteous, true professionals and get things done right.
Overall, we are satisfied. There is a training or communication matter that I would like to mention. For the past 5 years the treatment for ants was to spray in a very targeted way and not get any of the spray on outdoor furniture or pillows. This time it appeared that the spray got on the pillows and furniture,…
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!
Alberto returned to our home after we found a dead mouse in our crawl space. It ate bate prior to entering, then died. Alberto was able to look at options with us, rebaited all of our traps, placed some additional traps, and added a trap into the crawl space to monitor activity. He asked questions, and was very polite & helpful. Thank you, Alberto!

DEVANTE is our Regular, absolutely PREFERRED ... go-to Tech and we're always glad to see him for our…
