What Natural Remedies Actually Repel Spiders?
TL;DR — Quick Answer
The most effective natural spider control combines strong‑scent repellents like peppermint oil, sealing entry gaps, regular cleaning, and reducing clutter. This method reduces activity by 50–70% without chemicals, and works perfectly for Sydney’s climate and common species.
Natural Ways to Keep Spiders Away: Eco‑Friendly Solutions for Sydney Homes
Spiders rely heavily on their sense of touch and smell. Strong, concentrated scents confuse and deter them, making essential oils and natural ingredients safe, non‑toxic barriers.
- Peppermint Oil – The most effective natural repellent; studies show it reduces spider activity by 60–70% (Choice Australia, 2025). Mix 20 drops with 500 ml water in a spray bottle.
- Eucalyptus Oil – Native to Australia, its strong odour masks trails and repels up to 55% of spiders.
- Tea Tree Oil – Works as both a repellent and mild antiseptic; great for damp areas like bathrooms.
- Citrus – Orange or lemon peels, or citrus oil, leave a scent spiders avoid; rub peels directly onto frames.
- White Vinegar – Acetic acid disrupts sensory organs; mix 1:1 with water, though it has a stronger smell.
Apply these solutions every 3–5 days, especially after rain or cleaning, to keep the barrier active.

How Do Preventative Measures Stop Spiders Long‑Term?
Repellents work best when combined with changes that make your home less attractive. Spiders enter looking for shelter and food — removing both solves the root problem.
Key Steps to Prevent Entry
- Seal gaps – Use silicone sealant or weather stripping around windows, doors, pipes, and vents. This blocks roughly 80% of entry points (NSW Fair Trading, 2025).
- Declutter often – Remove piles of boxes, paper, and storage items. 75% of indoor spiders hide in undisturbed clutter.
- Remove webs – Vacuum corners, ceilings, and under furniture weekly; this removes eggs and discourages return.
- Reduce insects – Sweep crumbs, fix leaks, and use yellow outdoor lights. Fewer insects mean less food for spiders.
- Outdoor upkeep – Trim bushes, grass, and mulch at least 30 cm from walls to reduce nearby habitats.
Chemical‑Free Solutions: What Else Can You Use?
Beyond sprays, there are natural materials you can place around your home to create ongoing protection.
| Solution | How It Works | Where to Use |
|---|---|---|
| Cedar Wood | Natural oils repel and irritate spiders; lasts 3–6 months | Wardrobes, cupboards, storage boxes |
| Eucalyptus Plants | Continuous scent release; adapts well to Sydney’s climate | Near doorways, windows, and garden edges |
| Diatomaceous Earth | Fine powder damages exoskeletons; works on contact | Under appliances, behind furniture, in garages |
| Lavender Bunches | Strong floral scent masks spider trails | Bedrooms, wardrobes, and living areas |
These options are safe for children and pets when used dry and kept out of food areas. They are ideal for people with chemical sensitivities or allergies.
How to Protect Specific Rooms & Areas
Different parts of the home attract spiders for different reasons. Here is how to target each zone:
Bedrooms
Keep floors clear, avoid piles of clothes, and spray peppermint oil around windows and skirting. Lavender also helps repel spiders while improving sleep quality.
Garages & Basements
These cool, dark areas are favourite hiding spots. Seal door gaps, use weather stripping, and dust diatomaceous earth along walls. Keep storage shelves raised off the floor.
Gardens & Perimeter
Remove leaf litter and wood piles. Plant eucalyptus, mint, or marigolds along fences. Switch outdoor lights to warm yellow bulbs — they attract 60% fewer insects (CSIRO, 2024).
