The Fall Spider Invasion: What’s Luring Them Into Your Home

As the crisp fall air rolls into St. Louis, you might notice a few uninvited guests making their way indoors—spiders. These creepy crawlies often find their way into basements, attics, and other quiet corners of homes as they seek warmth and shelter from the cooling weather. While spiders may help keep other pests in check, most homeowners prefer them to stay outside where they belong. Let’s explore why spiders invade homes in the fall, how to discourage them from setting up shop, and why STL Pest Control is your best defense.

Why Spiders Come Indoors During the Fall

As summer fades, St. Louis temperatures drop, signaling a change in behavior for spiders. Spiders are cold-blooded creatures, meaning their bodies are regulated by the environment. Cooler temperatures can slow them down and even threaten their survival, which is why they seek warmer, sheltered environments during fall and winter. Your home provides the perfect haven.

Shelter and Food Sources

Spiders are driven indoors not just by the cold but also by the promise of safety and food. Homes offer:

• Warmth: Basements, attics, and wall voids maintain more consistent temperatures than the outdoors.
• Protection from predators: Inside your home, spiders face fewer threats from birds, wasps, and other predators.
• Insects to prey on: Spiders follow their food sources. If you have flies, ants, or other insects indoors, spiders won’t be far behind.

Reproductive Cycles

Many spiders, such as the common house spider and wolf spider, mate in the fall. This reproductive cycle encourages more movement as males leave their webs to search for mates. Once indoors, female spiders may lay eggs in hidden areas like storage rooms, wall cracks, or under furniture, increasing the spider population in your home over time.

Where Spiders Hide in St. Louis Homes

If you live in St. Louis, you’ve likely encountered spiders in some common areas:

1. Basements: Cool, dark spaces are perfect habitats for spiders. You might spot them in corners, under stairs, or inside storage boxes.
2. Attics and Crawl Spaces: These areas provide ideal hiding spots, especially for less-trafficked spiders like brown recluses.
3. Windows and Doorways: Spiders often enter through small cracks or crevices around windows, doors, and vents.
4. Fireplaces and Vents: Chimneys and vents offer easy access points, especially for species like the funnel web spider.

Common Spider Species in St. Louis

St. Louis homes attract a variety of spider species, some of which are harmless while others require more caution.

• Brown Recluse: One of the more dangerous spiders in Missouri, it tends to hide in dark, secluded places like closets and shoes.
• Wolf Spider: Large and intimidating but non-venomous, wolf spiders often come indoors seeking warmth.
• House Spider: These small, web-spinning spiders are harmless and often found in corners and windows.
• Jumping Spider: Known for their agility, these spiders aren’t harmful but can startle homeowners with their sudden movements.

How to Prevent Spiders from Invading Your Home This Fall

Although spiders help control other insects, most homeowners would rather not host them. Here are a few preventive measures you can take:

1. Seal Entry Points:
   Check around windows, doors, and vents for cracks or openings. Use weather stripping and caulk to seal gaps.

2. Declutter Your Home:
   Spiders love hiding in clutter. Organize storage spaces, discard unused items, and vacuum regularly to eliminate cobwebs.

3. Control Other Pests:
   Spiders follow their prey. If you can keep other pests, such as flies and ants, under control, spiders will have less incentive to stay.

4. Install Screens and Door Sweeps:
   Keep windows and vents covered with fine-mesh screens. Use door sweeps to block entry from underneath exterior doors.

5. Maintain Your Yard:
   Trim shrubs and trees away from your house, and keep firewood stored at least 20 feet from the building to discourage spiders from nesting nearby.
