The first frost is more than a signal that summer is over.
For many household pests, it’s a signal to find somewhere else to live.
As nights become colder across New Jersey, insects and rodents begin looking for food, warmth, and shelter. That’s why homeowners who haven’t noticed many pests all summer may suddenly start seeing them around windows, garages, basements, attics, and other parts of the house.
The good news is that you don’t have to wait until the first frost to do something about it.
Mice
Mice are one of the biggest fall concerns for homeowners.
They don’t need a large opening to enter a house, and once inside they can settle into wall voids, attics, crawl spaces, garages, and basements.
Fall is an ideal time to inspect potential entry points before colder temperatures arrive.
Look around:
- Foundations
- Garage doors
- Utility lines
- Attic vents
- Crawl spaces
- Rooflines
Stink Bugs
Brown marmorated stink bugs are classic fall invaders.
They begin moving toward protected overwintering locations in early to mid-September and continue until the first frost, according to Rutgers.
They often gather on sunny exterior walls before finding cracks and openings that lead inside.
Asian Lady Beetles
You may think you’re seeing harmless ladybugs, but some fall invaders are actually Asian lady beetles.
They can gather in large numbers on warm, sunny sides of buildings and may enter through cracks, vents, windows, and other openings.
Once inside, they can be difficult to remove.
Spiders
Spiders don’t necessarily move indoors simply because they’re cold.
Often, homeowners notice more spiders because the insects they feed on are becoming more active around buildings or because spiders are reaching maturity during late summer and fall.
If you’re suddenly seeing a lot of spiders, it’s worth considering whether another pest is providing a food source.
Boxelder Bugs
Boxelder bugs can become noticeable in the fall as they seek protected locations.
They may gather on exterior walls, windows, and other sunny areas before moving into cracks and sheltered spaces.
Like stink bugs, exclusion is an important part of long-term prevention.
Crickets and Other Moisture-Loving Pests
Crickets can become particularly noticeable around basements, garages, and other damp areas.
If your property has drainage or moisture problems, fall weather can make those conditions even more attractive to pests.
Why Fall Pest Prevention Works
Once pests have entered a wall void or attic, treating the problem can become much more complicated.
That’s why fall pest control should focus on prevention as well as elimination.
Walk around your property before temperatures drop.
Look for:
- Cracks
- Gaps
- Damaged screens
- Missing weatherstripping
- Open vents
- Holes around utility lines
- Gaps beneath doors
You should also inspect areas where moisture collects.
What About the First Frost?
The first frost doesn’t cause every pest to suddenly disappear.
Some insects die off.
Others enter dormant or overwintering stages.
Still others look for protected locations before the coldest weather arrives.
That’s why the period leading up to the first frost is an important window for fall pest prevention.
