"The owner was very friendly, responsive, and honest throughout the entire process. I had a few mice getting into my house, and he came out, set traps, and took the time to explain where they were most likely getting in and what to look for. He was straightforward, and knowledgeable. And havent seen a mouse since!"

"Encon is a great company! I had an ant problem and needed an exterminator right away. Based on good reviews, I called Encon in a panic and Debbie fit me in right away. Ryan came out to the house and talked with my husband. He explained the problem and sprayed around the foundation and inside where the ants seemed to be coming from. That night we had more ants then ever! I called in the morning and spoke to Debbie and told her what happened. She talked me off the ledge and explained how the nest was disturbed and that was normal. I was also happy with the cost. They were very reasonable. I will always call Encon for my pest control needs!"

Pest Control FAQs, answered by experts

Carpenter ants can go away on their own if their food source is eliminated, but this could take weeks or months. If you have an infestation on your hands, carpenter ants need to be treated by pesticides from a licensed professional in order to go away as soon as possible.

Termites are most active and cause the most damage during the spring and summer, as warm temperatures and increased moisture accelerate their activity. This is also when swarming typically occurs, allowing colonies to expand. However, termites remain active year-round, especially in warmer climates or heated homes. Once a colony is established, it can continue to damage wood 365 days a year, even during cold weather.

Some animals, such as bats or birds, will be able to get out of chimneys on their own since they can fly. Other animals, however, may have a harder time and will require the help of a professional to escape. Squirrels and raccoons in particular may become stuck inside a chimney, especially if you have a buildup of soot or creosote inside. This can prevent them from being able to climb out, in which case you’ll need to call an animal control expert to help remove them.

Bed bugs typically live between 10 months to one year, but they lay enough eggs that an infestation can continue to multiply and worsen without professional intervention. These pests can survive up to one year without eating, so you can’t expect a bed bug infestation to resolve without proper treatment.

Squirrels hate not having access to secure shelter or food sources. Your best line of defense is to make your property less attractive by removing access to these things. There are chemical squirrel repellents, but these have mixed success. According to Pennsylvania State University, you can apply products containing the bittering agent denatonium saccharide to a squirrel's favorite fence, tree, or roof spots. However, you need to reapply repellents regularly, which aren’t scientifically proven effective.
