When cold weather arrives in New Jersey, pests don’t go away—they move inside. Each winter, homeowners across NJ experience increased pest activity as insects and rodents seek warmth, shelter, and food inside houses, apartments, and condos. Kitchens are especially vulnerable because they provide everything pests need to survive.
Below are the most common winter pests found in New Jersey homes, why they invade kitchens, and how to prevent infestations before they become costly problems.
