Overwintering Pests

It’s the time of year when we all get ready for winter. We turn our heat on, put away our pool toys, and prepare ourselves for the long cold months ahead. But pests don’t take off their gloves and parkas just because it’s cold outside! Instead, they’re hibernating in your walls or under your floorboards. And once they wake up from their winter slumber, those pests will start multiplying like crazy—especially if you haven’t dealt with them already. Here’s what you need to know about overwintering pests:

What are overwintering pests?

Let’s start with the basics: a pest is any animal, insect or fungus that has been introduced to an area for which it is not native and causes harm to plants or animals. Pests have been around for a long time, but some of them don’t get enough attention during the winter because they’re dormant—or at least less active than usual. This doesn’t mean they won’t be bothering you next year—they just might show up in different places. If you want to know what pests are causing damage in your yard, house or garden now or in the future, these are the questions you should ask yourself:

  • What are overwintering pests?
  • How do I know if my home has pests over-wintering inside?
  • What can I do if my home has pests over-wintering inside?

Why do pests overwinter?

Pests that live in the soil (like voles, mice and other rodents) overwinter because their food supply is gone.

Pests that live in trees and shrubs (birds, squirrels) may do so for two reasons:

  • Shelter from the cold

How do I control overwintering pests?

So, you know about the pests and what they do. Now let’s talk about how to control them.

First things first: removing debris is the best way to reduce pest populations in your home. It’s easy enough to pick up a broom or vacuum when you see them (or at least get someone else to), but consider taking it one step further by hiring an exterminator or pest management professional (PMP) who can help keep your home from becoming infested with these pesky creatures in the first place. If you have time on your hands, though, cleaning up after yourself will go a long way toward keeping pests out of your house for winter.

Next up: insulate! This can be done by adding insulation into walls and attics specifically designed for holding heat during cold months; adding heating pads behind appliances such as refrigerators; installing window film that reflects sunlight back out on winter days so that temperatures stay warmer inside; sealing cracks in foundations where air seeps through from outside; tucking away pipes under sinks because if there are leaks then water might drip down into basements where pests could live too close by without realizing until it’s too late—I could go on forever here but hopefully these ideas give you an idea of how important insulation really is!

Pests can be a problem in the winter months, too.

Pests can be a problem in the winter months, too. You may find ants, flies and spiders still around after all of the leaves have fallen from trees. The pests that overwinter in your home are usually pests that bite or sting, such as bed bugs and fleas.

Preventing pest problems during the winter months is not difficult if you take a few steps each fall to make sure there are no cracks for pests to crawl through and no food sources for them to feed on when they first arrive inside your home. You must also make sure there are no places where water can collect on your property, which would provide shelter for these pests when they move into an area under cover like trees or bushes in order to escape cold temperatures outside during winter months.
