Spiders are most reliably repelled by strong scents (especially peppermint and other essential oils), physical barriers, and keeping their food sources down.

What Repels Spiders? (Quick Scoop)

1. Strong Smells They Hate

These are the classic answers when people ask what repels spiders.

  • Peppermint oil spray (top recommendation in many guides): mix ~10–20 drops with water in a spray bottle, spritz along baseboards, windows, and door frames.
  • Other essential oils:
    • Lavender oil.
* Eucalyptus oil.

* Tea tree oil (avoid around some pets).

* Lemon or other citrus oils.
  • Vinegar-based sprays: water + white vinegar + a bit of dish soap, often with lemon or other essential oils added.
  • Spicy or pungent scents: cinnamon sticks or oils, garlic in water spray, sometimes chestnuts placed on sills and entry points.
  • Cedar: cedar blocks or chips in cupboards and corners; spiders dislike the strong resin smell.
  • Herbs: rosemary sprigs on window sills are sometimes recommended as a gentle, natural repellent.

Many home and garden sites in 2023–2025 still list peppermint oil as the most effective “natural” answer to what repels spiders, especially when combined with regular cleaning.

Always check pet safety before using essential oils, especially around cats, dogs, or small animals.

2. Clean-Up & Home Setup

Even the best-smelling spider repellent fails if the space is perfect for webs and hunting.

  • Remove webs quickly so spiders don’t settle in (vacuum or broom).
  • Reduce clutter in corners, basements, garages, and under furniture so they have fewer hiding spots.
  • Seal gaps and cracks around doors, windows, vents, and foundations to block entry.
  • Turn off or reduce outdoor lights at night where possible; lights attract insects, which attract spiders.
  • Keep food sealed and trash closed to cut down on other bugs, reducing the spiders’ food source.

This “environment” approach is often mentioned alongside sprays as the long- term answer to what repels spiders indoors.

3. Natural But More “Physical” Options

If you want spider repellents that do more than smell nice, there are mild, non-spray tactics.

  • Diatomaceous earth (food‑grade): a fine powder used to create a barrier that small insects and spiders avoid crossing.
  • Sticky spider traps: they don’t “repel” but reduce the number of spiders inside, especially along walls and behind furniture.
  • Screens and door sweeps: keeping them in good repair is one of the simplest ways to keep spiders from ever coming in.

Pet-safe guides emphasize using food‑grade diatomaceous earth and placing traps where pets and kids can’t access them.

4. Chemical Sprays & Professional Help

For serious infestations or dangerous species, most sources stop talking only about “what repels spiders” and move toward control.

  • Residual insecticide sprays for baseboards, foundations, and outdoor perimeters are widely used by pest pros.
  • Aerosol “crack and crevice” products target hiding spots like gaps, under appliances, or wall voids.
  • Professional spider treatments are often recommended for black widows, brown recluses, or repeated large infestations.

These are effective but not “natural,” so they’re usually a last resort for people starting with peppermint and vinegar sprays.
