Important Notes:
- It may feel like spider activity increases in the fall, but in reality, overall spider populations drop as temperatures cool and food becomes harder to find.
- Even with fewer spiders, sightings tend to rise because they begin moving indoors to escape the cold.
- You’re more likely to notice spiders since you’re spending more time inside, sharing the same space they’re seeking for warmth and shelter.
- Tiny cracks and openings around windows, doors, and foundations provide easy access points for spiders to enter.
If you’ve ever noticed more spiders skittering across your floors or hanging in webs during the fall, it’s not just your imagination, there’s a reason for it. As temperatures cool and daylight hours shorten, spiders experience big changes to their environment. While many die off when food sources disappear, others begin seeking refuge indoors, which makes them far more visible.
These seasonal shifts cause spiders to alter their typical habits, forcing them to move, rebuild webs, and search for new hunting grounds.
Are Spiders Really More Active During Fall?
Technically no, their activity levels don’t increase much, but you’re more likely to see them during this time of year. Here’s why:
- In spring, spiders are still small and easy to overlook, even though they’re active.
- During summer, food is abundant, so they stay outdoors and don’t need to move around as much to find prey.
- Once autumn arrives, spiders often venture inside, looking for protected areas to build new webs or hide out.
- Larger spiders, which tend to live longer, are more common sights in the cooler months.
- Web-building species create bigger webs in fall and winter since fewer insects are flying, making their handiwork far more noticeable.
What Happens to Spiders in The Cold?
Cold weather presents major challenges for spiders and the insects they depend on. Most will die off soon after the cold air arrives, but some species are built to survive.
A few spiders can go through a process called cold hardening, which helps them tolerate lower temperatures. They’ll seek shelter in protected areas such as under tree bark, within leaf piles, around bushes, or tucked under eaves. Naturally, the warmth of your home is even more inviting.
Spider behavior also varies depending on the species. Some lay eggs before winter sets in, while others reproduce in spring. Although spider eggs can freeze, many egg sacs provide enough insulation for the young to survive until the days become warmer.

How to Keep Spiders Out of Your Home This Fall
Spiders sneak in through even the smallest entry points, so prevention is your best line of defense. Take these steps to keep them outside where they belong:
- Seal cracks, holes, and gaps around your home’s foundation, windows, and walls.
- Check screens for tears and repair them promptly.
- Install door sweeps or weatherstripping to close gaps under doors.
- Reduce clutter indoors and around the exterior to limit hiding spots.
- Keep bushes, plants, and landscaping trimmed back from your home.
- Regularly vacuum corners, ceilings, and other undisturbed areas to remove webs and egg sacs.
- Schedule routine spider control to keep your home fully protected.
Does Fall Make Spiders More Dangerous?
No, spiders don’t become more venomous or aggressive in colder months. They just tend to be closer to where you live and spend time. Indoors, they’ll find quiet corners or spots near water sources. As long as they’re left alone, they pose little risk.
Most spiders will only bite if they feel trapped or startled. Outside, they remain relatively inactive through the winter, venturing out only on warmer days before returning to their hiding spots.
