"Dave was excellent. He was professional, honest and thorough. I thought I may have squirrels in the house because I heard scratching above a ceiling and saw a squirrel climbing my chimney with acorns in it's mouth.  
Dave inspected all the outside areas of my house and looked in my attic. He found no evidence of squirrels or bats or anything else (other than a few mice that I can take care of).
He screened off my two gable vents and recommended securing a couple of other entry prone areas which I can do.
I highly recommend Colonial Pest Control.

"Shawn came out to my house within 24 hours, quickly assessed the wasp infestation in my backyard shed, and treated them on the spot. He returned six days later to check on everything and remove the empty nest, which my family and I greatly appreciated. Shawn’s communications with me via text, phone and email were outstanding throughout the process. I highly recommend Sully’s!"

"The person who came to the house was very nice and professional, but they are obviously very poorly trained because he told us that we had "march flies" and our second and third opinions told us that they looked nothing like a march fly. First, they told us they were termites, then march flies. They are neither."

Pest Control FAQs, answered by experts

Homes provide a stable environment with ample hiding spots, warmth, and protection from the elements, making them ideal habitats for spiders. The presence of insects within homes serves as a major food source for spiders, enticing them to establish their webs or burrows in and around residential structures. The nooks and crannies of homes provide perfect locations for spiders to construct webs or lay in wait for unsuspecting prey.

As a general rule, if you hear an animal in your attic, don’t assume it will stay there. Animals are drawn to warmth and food sources, which could lead them to other parts of your house. In particular, it’s likely that small pests such as rats and mice that only need tiny gaps to squeeze through will end up in your walls and ductwork. Larger animals like raccoons may be limited to an enclosed attic.

The fastest method to get rid of moles is, unfortunately, not the most humane one. Poison baits and traps are the quickest way to get rid of a mole infestation. 

However, the poison can be dangerous and even deadly to other visiting animals, such as birds, cats, and dogs. The toxins can even affect predatory birds who eat the moles after they've consumed the poison.

Fruit flies are more common during warm-weather months and may go away on their own in late fall once temperatures drop. However, they can survive year-round indoors as long as there's food available, so you'll likely want to take a proactive approach to get rid of them and stop the spread of bacteria.

Spraying for ticks does a good job of eliminating the existing ticks in your yard. Moderate to severe infestations might require several treatment sessions, but most infestations are well controlled with enough treatments, regardless of their severity.

However, wildlife, pets, and people can still carry ticks into a yard, even after treatment, so if you're concerned about ticks in your area, it's a good idea to spray annually for tick prevention.
