A Seasonal Guide from Humphreys Insect Control
When the temperature drops in Central and Northern New Jersey, pests do not simply vanish. Many of them look for warmth and protection indoors, which is why winter can be a surprisingly active season for pest control calls in Somerset County and Morris County.
If you have been searching “insect and pest control near me,” this guide breaks down the most common winter pests, the warning signs homeowners miss, and practical steps you can take to help keep your home pest-free.
Why pest activity can increase in winter
Your home offers three things pests need to survive: warmth, easy access to food, and safe hiding places. Humphreys Insect Control notes that winter is often when previously hidden infestations are discovered, including pests like silverfish and mice, and that storage areas such as attics, closets, basements, and garages are commonly targeted for interior treatment during the cold season.
Winter pests to watch for in New Jersey
1) Mice and rats
Rodents stay active all year. Once inside, they can nest in insulation, contaminate food, and cause damage by chewing. Humphreys lists sounds in walls or ceilings, gnaw marks, chewed wiring, and droppings among the signs that it is time to schedule a pest inspection.
Common signs:
- Scratching or scurrying sounds in walls or ceilings
- Droppings near pantries, cabinets, or storage areas
- Gnaw marks, holes, or damaged materials
- Chewed electrical wiring
2) Cockroaches
Roaches thrive in heated indoor spaces, especially where moisture and food are available. Kitchens, bathrooms, and utility areas are common hotspots. Humphreys specifically calls out roaches as a frequent pest issue their technicians handle.
Common signs:
- Roach sightings at night
- Musty odors
- Egg cases or droppings in cabinet corners and behind appliances
3) Ants
Some ant colonies remain active indoors during winter, often near warmth and water sources. Crumbs, spills, and moisture issues can keep them going.
Common signs:
- Small trails near baseboards and food areas
- Ant activity near sinks or plumbing
4) Spiders
Spiders often move into basements, garages, window wells, and storage areas in colder weather. While many are harmless, frequent sightings can signal that other insects are present as food sources.
Common signs:
- Webbing in corners and storage spaces
- Increased sightings in lower levels of the home
5) Overwintering insects
Some insects enter wall voids and attics to ride out winter, then show up on milder days.
Common examples:
- Stink bugs
- Lady beetles
- Cluster flies
- Boxelder bugs
A winter home checklist that helps prevent pests
Humphreys emphasizes protecting homes across all four seasons, with regular treatments that can control pests before they invade. Use this winter checklist to reduce risk:
Seal entry points
- Check gaps around doors, windows, utility lines, and the foundation
- Add door sweeps and repair damaged screens
Tighten up food storage and cleanup
- Store pantry goods in sealed containers
- Clean crumbs promptly, especially under appliances
- Use covered trash cans and take garbage out regularly
Reduce moisture
- Fix leaks and address condensation
- Improve ventilation in basements, bathrooms, and utility rooms
Declutter storage areas
Winter pest issues are often discovered in attics, closets, basements, and garages, so keep these spaces organized and easy to inspect.
When to call a professional pest control company
If you notice warning signs like droppings, egg cases, gnaw marks, damaged woodwork, chewed wiring, or unusual sounds in walls, it is smart to schedule an inspection rather than letting the issue grow. Humphreys warns that waiting can increase the risk of property damage and health problems.
