How to Keep Spiders Out Naturally with Mint Plants and Oil

Homes that feel warm and welcoming to us can be just as inviting to insects—spiders included. Few people are thrilled to see them skittering across the floor, and many would rather keep their living space calm and clean without reaching for harsh chemicals. There’s an easy, eco-friendly fix that leans on scent rather than sprays: aromatic plants, with mint at the top of the list.

Spiders, like many insects, are highly sensitive to smell. That’s the opening we can use. Potted mint—whether peppermint, ginger mint, or orange mint—releases a fragrance spiders can’t stand. Set a couple of pots on windowsills or near doorways, and you’ve built a natural barrier right where uninvited guests tend to slip in. As a bonus, the greenery freshens up the room and adds a crisp, lively note to your décor.

Not into houseplants, or short on space? Peppermint essential oil offers a compact alternative. Lightly soak cotton pads or small fabric squares with the oil and place them along windows, at thresholds, and in any corner where you suspect spider activity. This approach doesn’t just deter spiders; it can also help keep small rodents and mosquitoes at bay, making it a versatile household tactic.

Choosing a natural repellent has upsides beyond pest control. The scent of mint has a calming effect, helping ease stress and lift the mood. And because these solutions rely on plants and their aromas rather than chemical agents, they’re presented as safe options for homes with pets and children. In short: a few well-placed mint plants—or a handful of scented pads—can protect your space while keeping it fresh, pleasant, and welcoming to everyone but the eight-legged kind.
