If you’ve lived in Maine for a while, you’ve probably noticed a trend: spiders seem to appear more in and around your home when the evenings get cooler and the days get shorter. But is there really such a thing as “spider season” in Maine? Let’s break it down.
Do Spiders Really Have a Season?
Technically, spiders are around all year long. They don’t migrate, and they don’t completely disappear in winter. However, in Maine, homeowners notice them most in late summer and fall. That’s because many spider species reach maturity this time of year, which means two things:
- They’re bigger, making them easier to spot.
- They’re looking for mates, and sometimes that brings them indoors.
So while spiders don’t have an official “season,” fall is definitely when you’ll notice them most.
Why You See More Spiders in the Fall
Here are a few reasons homeowners often spot more spiders inside during autumn:
- Mating season: Adult male spiders are on the move, searching for females.
- Cooler weather: As temperatures drop, spiders may wander indoors for shelter.
- Indoor hiding spots: Basements, attics, and garages provide warmth and protection.
Common Spiders in Maine Homes
While most spiders you see indoors are harmless and actually help control other pests, that doesn’t mean you want them crawling around. Some of the most common household spiders in Maine include:
- Cellar spiders (aka “daddy longlegs”): Thin-bodied with extra-long, delicate legs, these spiders lurk in basements and corners of garages.
- House spiders: Classic web-builders you’ll notice in windowsills and ceilings.
- Wolf spiders: Larger, ground-dwelling hunters that sometimes wander inside.
- Jumping spiders: Small but active hunters with excellent vision, often seen on walls and window sills.
The good news: Maine doesn’t have to worry about dangerous spiders like the venomous brown recluse.
When Spiders Indicate Other Pest Problems
Spiders don’t show up in your home by accident; they follow their food. If you’re noticing more spiders than usual, it could be a sign that other insects are thriving inside your home. Flies, ants, silverfish, and even mosquitoes are common food sources for Maine spiders. A surge in spider webs or sightings may mean:
- There’s a hidden insect problem you haven’t noticed yet.
- Your home has areas with high moisture or clutter where pests are thriving.
- Outdoor lighting is attracting more insects, which in turn attract spiders.
Simply put, more spiders often mean more prey, which could point to a bigger pest issue that needs to be addressed.
Tips to Reduce Spiders in Your Home
If you’d rather not share your living space with arachnids this fall, here are a few spider prevention tips:
- Seal cracks and gaps around doors, windows, and foundations.
- Keep basements, attics, and storage areas clutter-free.
- Reduce outdoor lighting near entry points (lights attract the insects that spiders feed on).
- Regularly vacuum and dust to remove webs and egg sacs. Be sure to throw the vacuum bag out immediately after.
