Spiders in the Home: Why They Appear in Autumn and How to Keep Them Away Effectively

September 8th, 2025

With the arrival of autumn, it’s not uncommon to see more spiders inside homes. While
they are useful for controlling harmful insects, their presence can cause discomfort.
Understanding why they appear in this season and knowing effective ways to deter them
will help keep your home healthy and welcoming.

Why Are There More Spiders in Autumn?
In autumn, outdoor temperatures drop and spiders seek a warm place to survive and
reproduce. Homes offer not only shelter from the cold but also a food source thanks to
small insects found inside. The most visible species at this time are often males moving
around in search of females to mate with.

How to Prevent Their Presence Indoors?
1. Seal Entry Points: Inspect window frames, doors, vents, and wall cracks. Use
caulking or weatherstripping to limit access.
2. Reduce Food Sources: Fewer insects indoors means less reason for spiders to
stay. Use screens and maintain good household hygiene.
3. Keep Outdoor Areas Clear: Move firewood piles, fallen leaves, and bushes
away from your home, as these are perfect shelters for spiders.
4. Vacuum Regularly: Vacuuming not only removes visible spiders but also their
eggs and webs.
5. Use Natural Repellents: Peppermint essential oil, white vinegar, or lemon are
known to repel spiders. Spray these solutions near high-risk areas.

When to Call a Professional

If you notice a significant infestation or your preventive efforts aren’t enough, a pest
control specialist can identify the species present and apply a safe, effective treatment.

By following these tips, you can reduce the presence of spiders in your home during
autumn while respecting their beneficial role in the ecosystem.
