    Dan came to take care of wasps that were nesting in an opening in my siding. It was the day after a…read moresnowstorm, and the wasps were not active. Dan treated the area even though the wasps weren't active that day, and were possibly dead due to the storm. He did not charge me that day, and told me that if there was evidence of more wasps later on to give him a call. Dan was so professional, courteous, and honest. I told him I would like to pay him something, but he refused. I will certainly call him again if I have evidence of wasps nesting in my siding. I very highly recommend Dan and Eco Tech Pest Control.

    Eco Tech came out to spray a hornet's nest for my house that I am renting out. It took me a while…read moreto get a hold of the technician to schedule a time to come out after I got an online quote (apparently the number on the website is the overall corporation # but then the local Denver people have separate phone numbers). Once I got a hold of him, we scheduled a date and time. And then I never heard from him again until I received an invoice via email. I would have expected him to let me know he was at the house or at least finished spraying at the house- let me know what he saw and what he did and that it was gone. My tenants just said the nest was gone so I did not follow up. I hire a lot of contractors for my properties and I'm used to some kind of communication or follow up so this was just odd to me. I appreciate the prompt and fair quote, the fact that he did come out, and that he sprayed it.

    Beware!!!! They give you an A+ presentation, but their delivery is a D-…read more They bid $2470 to protect my house from wild critters. Their workman was here for 6 hours and did not have a work order telling him what to do...I had to direct his work. After I complained about their poor performance, they refunded $750.

    My mother called Critter Control (Boulder) for service. She is 86 years old and confined to a…read morewalker. She has been hallucinating and sees "critters" in her bedroom. It is obvious to anyone with half a brain that there is nothing there. The critter she described to Critter Control was a rodent with blue eyes.... (based on a google search, NO rodents have blue eyes). There are no droppings and no evidence of any rodents in the house, specifically in the bedroom where my mother "sees" them. I put sticky traps out myself and even left a slice of bread under her dresser for weeks without it being touched. Critter control (Spencer Gildersleeve and Dana Carwin) still found it acceptable to do an initial service for $329 and two follow up visits for $95 each ($519 total). I am appalled that Critter Control would take advantage of an old woman by taking her hard-earned money. None of their indoor traps have caught a single thing and no evidence of any "critter" has been found. I've spoken with 3 people at Critter control including Dana Carwin who arranged the contract with my mother. Dana said a manager would call with possible restitution, but I have not received any further communication. Critter Control did respond to my review on Yelp with "Will look into it" (two years ago)...... So either Critter Control technicians are clueless or they are willing to rip people off, either way I would never use their service..... this is a repost since I saw Critter Control with a 5 star rating in the Boulder County "Five Star Rated" guidebook.... with this in mind, I wouldn't trust any other recommendations in that book. Received a response from Adrienne (below), thanks for a response, although two years late. However, your response has one major hole in it. You said your Technician communicated to both ME and my mother that no evidence of pests were found..... I live 12 miles away and was no where near my parents residence during any of the Critter Control visits. Had I been there I would have declined the "service".
