As we enter the final week of fall, Sacramento is already feeling more like winter. Cold mornings, foggy days, and consistently low temperatures have settled in earlier than many of us expected — and while we’re pulling out jackets and turning up the heat, pests are doing the same thing… just in a different way.
For insects and rodents, falling temperatures signal one thing: find warmth and shelter fast. Unfortunately, that often means homes, garages, and crawl spaces.
Why the End of Fall Triggers Pest Activity
Fall is one of the most important transition periods in pest behavior. As outdoor conditions become less hospitable, pests start moving closer to structures in search of:
Warmth
Food sources
Safe nesting areas
This is especially true during colder-than-normal seasons like the one Sacramento is experiencing now. Rodents, spiders, ants, and other overwintering pests don’t wait until winter officially begins — they start preparing early.
If your home isn’t sealed, protected, and treated, pests can move in before you even realize it.
Common Pests We See This Time of Year
During the last weeks of fall, we commonly see an increase in:
Rodents (rats & mice)
Rodents are notorious for seeking indoor warmth as temperatures drop. They can squeeze through openings as small as a quarter and often enter through garages, vents, or gaps along foundations.
Spiders
While many spiders are harmless, they follow insects indoors — and cooler weather pushes both inside. Homes become attractive shelters where spiders can hide and build webs undisturbed.
Ants
Ants may slow down in extreme cold, but fluctuating temperatures and indoor heat sources can keep them active well into winter.
Other overwintering pests
Earwigs, silverfish, and cockroaches are all looking for moisture and warmth as outdoor conditions become less favorable.
Why Waiting Can Cost You More
One of the biggest mistakes homeowners make is waiting until pests are already inside. By the time you see activity:
Rodents may already be nesting
Entry points have already been compromised
Damage may already be happening
The last week of fall is the ideal time for prevention. Addressing pest issues now can save you stress, repairs, and higher treatment costs later in the winter.
