With the changing leaves, crisper temperatures, and fall festivities starting up, you may be thinking Long Island’s peskiest pests are on their way out! In fact, it’s a common misconception that insects “die off” during the chillier months of the year. Today, we’re breaking down the truth on where pests go during the fall and winter, which critters you’ll start to see more of, and why an annual pest control plan is always the answer!

Where Do Insects Go During Cold Months?

As mentioned, you may have heard time and time again that pests like ants, roaches, and spiders “die off” or leave your home once temperatures on Long Island start to drop. That’s just not the case!

In the fall and winter, many pests will actually become even more active inside your home, because it’s cold outside to them, too! Many insects and other household pests will utilize any available nook or cranny to make their way into your home for a cozy place to enjoy autumn.

What is Overwintering?

Because many insects are exothermic, which means they rely on external sources (like your home’s heater) to provide the heat they need in order to survive, the process of overwintering is common. Overwintering is a way in which pests essentially wait out the cold winter months that are coming through methods of hibernation and migration. 

One example of overwintering would be roaches, which are exothermic pests. During colder months, roaches will move indoors to areas like your basement or crawl space in search of a comfortable place to wait out the chilly weather.

There are several pests on Long Island that are synonymous with fall; we’re breaking down five of the pests we get the most calls about this time of year.


On Long Island, we see two key species of mice this time of year: deer mice and house mice.

Deer Mice

Deer mice are generally found in fields, wooded areas, and farmlands. Compared to house mice, deer mice (or white-footed mice as they’re often called instead), are less likely to invade your home. When they do, they’re usually found nesting behind walls and inside attics and chimneys. They’re known for chewing through wires and wood and can destroy gardens and landscaping, in addition to contaminating food.

House Mice

House mice are commensal rodents; this means they are at least partially reliant on humans for food, water, and shelter. In homes, they’ll hide behind walls, in attics, basements, crawlspaces, and behind appliances. These critters are dangerous to the structural integrity of buildings and will chew through wires, pipes, insulation, flooring, and even drywall.

Norway Rats

Norway rats are another rodent that’s commonly seen in Long Island homes during the fall. They’re terrible climbers, so if they do get into your house, it’s likely they’re going to be in the basement, on the ground level, under piles of debris, or in your crawl space. Norway rats have extremely strong jaws and teeth and can chew through virtually anything. For these pests, no pipes, flooring, drywall, or personal belongings are off-limits to their chompers.


Squirrels are another furry critter many Long Island homeowners battle during the fall. When temperatures drop, they often enter homes through roof edges, vents, missing shingles, or any other opportunity they see! They’re known to chew wires, building materials, insulation, rafters, furniture, and personal belongings once inside.
