Bearclaw Wild Life take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job

"I hired this company as I heard wildlife activity in my chimney. They were very responsive and Matt even confirmed the appointment. He sent someone else even though it was twice confirmed it would be him. The tech that arrived walked about 20 feet into my living room, shined a flashlight into my fireplace and told me the wildlife was protected and couldnâ t help. I was promptly charged $133. I had agreed to this fee, as it would have been applied to the job had I hired them to do the work. I had every expectation of hiring them, but as they couldnâ t help, I did not have that option. I have no problem paying a fair price for services performed, but a 5 minute call does not warrant this expense."

Your home will be inspected & documented w/annotated phots provided to show what has made it in and how including but not limited to water in your basement, mice, bats, flying squirrels. In addition, This will help you understand what needs to be done to stop them from getting inside in the first place and then we can professionally seal it with non-chewable materials. We service lower Fairfield County, CT and parts of Westchester County, NY. Brian’s career in the pest control business began over 25 years ago. He spent three years in the southern United States learning from a world-renowned entomologist (among others) and helped start the Sentricon baiting program for termites with Dow Elanco. Brian advanced through the field to eventually run a major sales force and acquired a distinctive edge in the business. Through this experience, Brian realized he wanted to return to his home state of NY and create his own niche in the rodent control market. He developed a highly successful approach, rejecting the easy but environmentally unsound approach of poison – and instead relying on hard work, common sense, and the correct materials to prevent rodents from entering people’s homes in the first place. Fast forward a few years, and Brian began to realize there were additional niches in this area that needed to be more friendly towards the environment and the clients’ health. He therefore co-invented the Enviroboot® Dust Suppression System to help control the toxic silica dust that is produced when concrete is broken with a jackhammer. The result was a reduction in toxic dust greater than 97% according to the EPA and was awarded the 2006 US EPA CLEAN AIR EXCELLENCE AWARD. Brian M. Sweig has a special set of skills and licenses in NY and CT including Nuisance/Wildlife, Home Improvement, and Home Inspection (CT), Mold Assessment and looks forward to helping make your home a better place for you and your family.

"Brian and his team are wonderful. I give them an A+ rating for the service they provided in both my home and my parents. Brian is professional tohis core, honest and fair with his cost. He explains everything that needs to be done and does a great job fixing the problems."

Garrie Pest Control is a Full service pest control company which has been providing state-of-the-art pest control to the Tri-State area for over 40 years. We are one of a select group of companies authorized to provide the Sentricon* System which totally eliminates termite colonies using ounces of low toxicity pesticide.

"They are very nasty / rude and not professional on the phone. When we call, it takes almost a week for them to show up. We recently called and scheduled for a date and when they Didn’t show up we called them again and they said no one called to schedule anything and we’re very rude about it. I’ve been a client with them for just over 3 years. The first year was amazing service but the last 2 years is making me look into other options."

Pest Control questions, answered by experts

Carpet beetles do not bite humans, but their larvae can cause skin irritation that’s often mistaken for bites. These tiny, bristly larvae have barbed hairs that can lead to allergic reactions in sensitive individuals, resulting in red, itchy welts or rashes. While the irritation may resemble bug bites, it’s actually a response to contact with the hairs or shed skins, not an actual bite. Adult carpet beetles are harmless and primarily feed on pollen, but their larvae can damage natural fibers like wool, fur, or leather in carpets, clothing, and upholstery.

Allowing wolf spiders to reside in your home can have benefits, as they serve as natural exterminators, preying on insects and pests that could become problematic. Their presence can help keep your residence relatively free of nuisance insects such as flies, ants, and cockroaches, reducing the need for chemical pesticides. Wolf spiders are generally not hostile towards humans, and their bites, although painful, usually don't result in a significant medical concern. If you can coexist peacefully with these spiders and recognize their role in maintaining a balanced ecosystem within your household, they can contribute to a healthier and pest-reduced environment.

Wasps are attracted to three primary things: Bright colors, food sources, and softened wood they can use for nests. They are more active in warmer months, which is when outdoor flowers and dinners also become more common. You can decrease the attention of wasps by keeping trash bins closed and avoiding bright flower colors in furniture or tablecloths.

Homemade raccoon repellents can be a cost-effective and humane method for keeping raccoons off your property. Raccoons despise the smell of vinegar, so keeping a bowl of it near your home can keep them away. Some wildlife companies advise using cayenne pepper or hot sauce sprinkled near your deck or porch as another homemade option.

Knowing what attracts mice to your house can help you figure out how to eliminate them or prevent them from ever appearing. Mice visit your house for two main reason:

  1. Access to food or water: Mice eat everything from grains and seeds to fruits and veggies. They’re also thirsty critters that return to leaky faucets and pet bowls. 

  2. Access to shelter: Mice flock to any place that’s warm, hidden, and viable for shelter. That might be an insulated attic, a crack in the wall, or a cluttered indoor area.
