Fall Spider Defense in Annapolis, MD: Late September & Early October Guide

As temperatures start to dip in late September and early October, folks in Annapolis, MD often notice more spiders inside their homes. This seasonal spike can be unsettling—but with the right knowledge and preemptive action, you can keep your home spider-free this fall.

Why Spiders Become More Noticeable Now in Annapolis

One of the main reasons spiders are more visible in the fall is that mating season peaks in late summer. Many species mature by September and become more active as they seek mates, which means you may see them in hallways, kitchens, and other indoor spaces.

Another factor is indoor movement. Some spiders have been in your home all summer, staying in less-used spaces like basements, attics, and crawl spaces. As the seasons change, they begin to wander into living spaces.

Along the East Coast, including Maryland, this seasonal shift is common and aligns with an uptick in spider sightings inside homes.

Common Spiders in Annapolis Homes

Wolf Spiders – Large, fast-moving hunters that can startle homeowners but are not considered dangerous. They often come indoors during fall to hunt prey.

Jumping Spiders – Small, fuzzy, and agile. These spiders are harmless to humans but often appear near windows chasing flies.

Orb-Weavers – Large web-builders often seen in gardens and around outdoor lights in early fall. Non-venomous and beneficial, though their webs can be inconvenient.

Cellar and Cobweb Spiders – Thrive in dark, damp corners of basements and attics. Completely harmless but can contribute to a “cobwebby” appearance in your home.

Black Widow Spiders – Shiny black with a red hourglass marking. These are venomous and require caution. They are uncommon indoors but may be found in sheds, garages, or woodpiles.

Marbled and Orchard Orb-Weavers – Colorful spiders common in Maryland during fall. They are beneficial garden predators and rarely come indoors.

Joro Spiders – A recently arriving species from East Asia, recognizable by their bright yellow and red markings. Harmless to humans and not yet widespread in Annapolis, but sightings are increasing in Maryland.

Eco-Smart Prevention: Keep Spiders Out This Fall

Here’s how to protect your Annapolis home this season while respecting the ecosystem:

1. Seal Entry Points

Check for cracks around doors, windows, vents, and utility lines. Caulk gaps, replace worn weather stripping, and repair torn screens. This prevents not only spiders but other insects from coming inside.

2. Declutter and Keep It Dry

Spiders thrive where there’s plenty of hiding space and prey. Store firewood away from your home, remove debris piles, and reduce moisture in basements and crawl spaces by using dehumidifiers.

3. Use Natural Repellents

A natural spider repellent can be made by adding 10–15 drops of peppermint essential oil to a spray bottle of water. Mist door frames, window sills, and corners. Many spiders dislike strong scents like peppermint, citrus, or lavender.

4. Practice Humane Removal

If you do see a spider indoors, avoid squashing it—especially if it’s carrying an egg sac. Use a jar and a piece of paper to capture and release it outside, or use non-toxic sticky traps in problem areas.

5. Manage Outdoor Lighting

Lights attract insects, which in turn attract spiders. Use yellow or warm-hued outdoor bulbs, and consider turning off porch lights when not needed.
