The Worst Pests to Have in Winter

As the weather gets colder, you might think your pest problems will taper off. Most people think most invaders just die off in the cold and populations bounce back in the springtime, but the reality is more complicated. Many pests, particularly rodents and bugs, are just getting started when winter approaches—they know your home represents a warm source of shelter, so they’re going to do everything they can to move in and get set up. You need to be ready to battle some of the worst pests in winter in Rochester, NH, and the first step is knowing who your biggest adversaries might be.

Norway rats

These little rodents can resemble mice, and they can slip through openings as small as ½ inch. They are very active chewers and will gnaw through just about anything (even pipes) to get at sources of food or water. They can very quickly cause immense damage, and can even carry diseases like jaundice and cowpox that could harm your family. Before the weather gets too cold, inspect the exterior of your home for any gaps, and caulk or otherwise seal them. You should also get rid of any sources of moisture in the basement—Norway rats will often be on the lookout for drinking water, and this can draw them inside.

German cockroaches

This is the most common species of cockroach in the world, and they love to find little domiciles that are plentiful in food and water. Unfortunately, they often find these inside of your home. Cockroaches are one of the worst pests in winter in Rochester, NH because they can make allergies and asthma symptoms worse, especially in children. This is due to the fact that they are so adept at contaminating food and spreading pathogens around your home.

Cockroaches like to enter homes by hitching a ride in items like grocery bags or things bought secondhand, so be sure to carefully inspect anything you purchase before you bring it into your house. Keep your kitchen spotless and vacuum frequently to eliminate their food sources and you stand a better chance of holding them off.


Raccoons are winter pests that infest homes in Rochester, NH via attics or gaps in chimneys as they search for a site to set up a den. They can also create a home in your woodpile, so make sure yours is located well away from the walls of your house. Raccoons are legendary foragers, so they can be kept largely at bay by making sure their favorite food sources are inaccessible. This includes keeping your garbage cans tied up with bungee cords and replacing any loose siding or shingles on your home. It’s also a good idea to put wire mesh over spaces like chimneys or dryer vents to seal up those potential access points.
