"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.

"I had a fantastic experience with Milltown Pest Control! They came out quickly and treated a ground hornets nest in my horse paddock. They assured me that all the products used were animal safe and would bring no harm to my horses. They fixed my problem quickly and were extremely friendly and easy to work with. Would highly recommend this company to anyone, especially if you have animals and want to be sure they are safe."

"Have a terrible mole infestation in my front yard, contacted Brian and he was here the next day, he arrived two days later to start the job, he was very down to earth ( no pun intended) and very professional. I will be recommending him whenever I get the chance Kevin H"

Pest Control FAQs, answered by experts

There aren’t any solutions that can rid your yard of mosquitoes for good. But with a good integrated management strategy that combines repellents, treatments, decluttering, and drainage, you can keep populations in check.

If you’ve had a prior bat infestation or simply want to avoid having bats invade your home in the first place, there are a few steps you can take without the need for a pro. 

  • Seal entry points, such as where your chimney meets your house, or other gaps or holes exist.

  • Use bat deterrents like bright lights or ultrasonic devices to force them away from your home. 

  • Reduce bat attractions like standing water and bird nectar feeders inviting bats into your yard.

Chirping noises, droppings, scratches on the walls, and stains at entries and exits are all signs that you have bats in your house or, more specifically, your attic. Because bats are nocturnal, there’s a chance that bats have already infested your home before you start to see warning signs, so don’t delay if you notice anything. If you see a bat or two at sunrise or sunset near your property, that’s another telltale sign that they could be setting up shop inside your space.

There are quite a few opinions regarding using coffee grinds to keep deer out of your garden, with many people convinced of this method. It makes sense that it could work considering deer have a strong sense of smell and likely do not like the smell of coffee grounds. However, there’s no hard evidence supporting the notion that coffee grounds keep deer away, but it may be worth trying.

If it seems like many flies appeared in your yard overnight, don’t be concerned. A single fly can lay over 200 eggs per day, so having one in your yard could lead to dozens more the next day. That’s why it’s important to eliminate flies from outside your home before they take up residence.
