What Are the Most Common Winter Pests?

March 18, 2024

As winter sets in across the United States, a variety of common pests seek shelter in homes to escape the blistering cold. Winter bugs in houses can quickly become a nuisance and understanding these pests and bugs can help homeowners implement effective winter pest control and pest prevention measures.

Below are five common winter pests that can invade your space in the cooler months:

Rodents (Mice and Rats)

Rodents are notorious for seeking warmth and shelter in homes during the winter. They can enter homes through small cracks and gaps in walls, floors, and foundations. Once inside, they can cause serious health consequences and costly damage by gnawing on wires, insulation, and contaminating food containers.


Cockroaches are resilient pests that can survive in a variety of environments, and they thrive indoors in the winter. These winter insects enter homes in search of warmth, water, and food. Cracks in walls, gaps around doors and windows, and sewer lines are common entry points for these creepy crawlies.


Spiders make their way indoors during the winter in search of prey and shelter. Like most winter invaders, they usually enter homes through small openings, such as gaps around windows and doors, vents, and cracks in walls. It is important to note that while most spiders are harmless, some species can pose a threat to humans and spider infestations should always be taken seriously.


Certain ant species, like Argentine ants and common odorous house ants, are known to invade homes during the winter months in search of food and shelter. They can enter through tiny cracks and crevices around doors, windows, and pipes. What’s interesting is that once inside, the tiny invaders are able to leave scent trails to attract more ants to your home.



Although termites are most active during the warmer months, their activity does not stop when winter approaches. Subterranean termites actually remain aggressive feeders during the cooler months and pose a constant risk to a home's structural integrity. To prevent infestations, it's vital to pretreat your home and stay vigilant for signs of termite activity year-round.

These winter pests can not only be a nuisance but also pose serious health risks and have the ability to cause property damage if left unchecked. Implementing preventive winter pest control measures and seeking professional pest control assistance will help mitigate the risks associated with winter pest infestations.

Why Is Pest Control Important in Winter?

Winter poses unique challenges for homeowners because despite the cold weather, winter bugs in house remain a persistent concern and effective pest control during this season is vital for a variety of reasons.

As temperatures drop in the cooler months, pesky pests such as rodents, cockroaches, and ants seek shelter indoors, making homes susceptible to vast infestations. These common winter pests not only cause structural damage to property, they also pose serious health concerns and can even contaminate food supplies.

Termites are also a concern in the winter months. Although typically associated with warmer months, these creepy crawlies actually remain active during the winter, particularly subterranean termites. Their continuous activity in the winter months highlights the importance of year-round pest control to prevent costly damage to homes.

It is also important to note that neglecting pest control in winter can lead to a proliferation of pests in the spring when temperatures rise, exacerbating infestation issues. Preventive measures taken during the winter can significantly reduce the likelihood of future pest problems.

By prioritizing pest control in winter, homeowners can safeguard their properties and ensure a comfortable living environment throughout the year. If winter home invaders are detected, seeking prompt assistance from pest control experts will effectively mitigate infestation risks and preserve the integrity of the home throughout the year.

Winter Pest Control Tips

Maintaining effective pest control during the winter months is essential, especially in regions like New Jersey where temperatures drop below 50 degrees Fahrenheit. To keep your home pest-free during this snowy season, consider implementing the following tips:

  • Block Entry Points: Inspect your home for cracks and gaps around doors, windows, and the foundation. Seal any openings with caulk or weather stripping to prevent common winter pests like ants, roaches, and spiders from infiltrating your living space.
  • Eliminate Food Sources: Pests are attracted to food and water, so keep your kitchen clean and free of crumbs and spills. Store food in airtight containers, promptly clean up after meals, and seal garbage cans tightly to discourage pests from finding a meal in your home.
  • Trim Trees and Vegetation: Cut back trees and shrubs that are in close proximity to your home, as they can serve as bridges for pests to enter. By maintaining a clear space between vegetation and your house, you reduce the risk of pests making their way indoors.
  • Invest in Preventative Pest Control Services: Regular treatments can create a barrier against pests and help prevent infestations year-round. Consider scheduling service visits every few months to maintain protection.
