Key Takeaways:
- Itย seemsย like there are more spiders, but there arenโt. There are actually fewer spiders because many die off when the weather cools down and food becomes more scarce.
- Even though there are fewer spiders in the fall, you are more likely to see them for a few reasons.
- Many spiders come inside in the fall, seeking warmer shelter, and you spend more time inside during this time, making it more likely that you see one.
- Spiders can get into your home through tiny cracks and gaps in your homeโs exterior.
If it feels like you always see more spiders in the fall, itโs not a coincidence โ there is actually a reason for it. In the fall, temperatures start to drop and daylight hours shorten, and while these seem like small changes, theyโre actually quite massive to spiders. Due to the cold and less available food, many spiders die off, so there are actuallyย fewerย spiders in the fall. So, why does it seem like there are more spiders in the fall?
These changes set off a chain reaction that forces spiders to alter their habits, which served them well throughout the spring and summer.
Are Spiders More Active in Fall?
On average, spidersโ activity level is about the same, but theyโre more noticeable when they’re active in the fall. Here are a few reasons why:
- Spiders are young and small in the spring, so even while theyโre active, theyโre much harder to notice.
- In the summer, food is abundant. They donโt have to travel as far hunting, and for web hunters, their webs are at their most effective.
- In the autumn, they move inside. They have to reestablish new habitats, and you often see them during this transient period.
- Large spiders, which are easier to notice, typically survive longer into fall and winter than small spiders.
- With fewer flying insects to capture in the fall and winter, web hunters are forced to build larger webs, which are more easily noticeable
What Happens to Spiders in Fall?
The colder temperatures of fall bring numerous existential threats to spiders and the insects they eat to survive. Many will die off within a short time of cooler weather arriving. However, not all.
Certain spider types can undergo “cold hardening,” a process that allows them to acclimate to dropping temperatures. They will still seek refuge from harsh weather in places like leaf piles or tree bark, in bushes, or under your roof overhang. However, your warm home offers a much more appealing sanctuary.
Spider behavior in colder months varies by species. Some spiders lay eggs in the fall, while others do so in the spring. While eggs are vulnerable to freezing, spiderlings can endure cold temperatures within egg sacs.
What Types of Spiders Are You Most Likely to See in the Fall?

- Orb-Weaver Spiders
How Do I Keep Spiders Out of My House in Fall?
Spiders can make their way inside in several different ways. The most important things you can do to prevent them are seal any cracks or gaps in the exterior of your home, and make sure the area immediately outside your house offers minimal spider harborage areas.
- Seal holes in windows and storm door screens.
- Close gaps around doors with a proper fitting or a good door sweep.
- Remove clutter in and around the house to eliminate hiding places.
- Keep landscaping around the house trimmed.
- Vacuum or brush corners and ceilings to eliminate cobwebs.
Are Spiders More Dangerous in Fall and Winter?
No, theyโre not more dangerous in the fall and winter โ they just might be in closer proximity.
Inside your home, theyโll often find a place in a corner or under clutter thatโs in proximity to a water source. If you donโt disturb them, they wonโt disturb you. Spiders are not aggressive, but if you try to handle them or accidentally come in contact with them and surprise or scare them, they may bite.
Outdoor spiders are less active in the winter, generally staying in whatever shelter theyโve found. They will come out on warmer winter days but otherwise are much less seen than at other times of the year.
