*UPDATED* I rarely update reviews once I post them, because I find it important that customers get my initial feeling on something. However, with this company, I have to make an exception. I had a problem with my original service. I wasn't a customer looking for a refund, or a customer just here to complain, but the reality was I had certain expectations for what the service could provide because of what sales staff told me upfront that simply weren't being met. In stepped Derek, the owner, a
I've never had a problem with any of the techs , they have all done a great job. I think it's family owned which I like to support, and more people should. Also if there's any issue in between the service job done all you do is call them and they will send out a technician at no extra charge, which I only needed done once and that was at the beginning of using them ....I had a LOT of spiders and those Chinese harmless crickets but they are big and freaky looking. Now we have absolutely NONE th

Wild Life Control Solutions did a huge project for us 10 years ago. We were in the process of buying a house and during the inspection over 200 bats were found living in the attic. Art was knowledgeable, reassuring and extremely professional. We were given a 5 year guarantee on his work and every time we‘ve had work done to the exterior of our home, Art has come by to make sure our house has not been compromised. Yes, Art is expensive and rightly so. His work is worth every penny.

Thank you for the kind words. It’s hard to believe we are just three short years away from 40 years in the business of Animal Damage Control and repairs. As always, we are committed to doing the job right the first time and standing behind our work.
It was a great experience from the very first phone call. The person who answered the phone was very professional and was very sympathetic with our problem. Alec showed up just a few hours from when I called. He came in with no fear, had a lot of knowledge about the problem, and easily found a solution. (Which was wasps inside my home! ) So glad I found All Solutions! We will continue to use them from now on for all our pest issues.

We had a raccoon get under our deck and into the basement drop ceiling. Art came out did his inspection, located raccoon prints on the deck and hot tub. Art set up a trap by the gap between the deck and hot tub. With in 24 hours he had the raccoon. Art then fabricated a heavy mesh to surround the hot tub to prevent any further issues. It looks excellent! I can highly recommend Wildlife Control Solutions.
