Lavender is a natural spider repellent that is nontoxic to humans and plants. You can use it on yourself and your pets to prevent spider and tick bites, as well as around the house and in your garden to repel spiders. A study in the Acta Phytopathologica et Entomologica Hungarica Journal found that French lavender oil was toxic to mites, which are a type of spider. A 2 per cent solution of lavender oil worked the best against spotted spiders, according to a report made by the Certified Organic Associations of BC (COABC). The 2 per cent solution is strong enough to repel spiders, yet gentle enough not to harm plants, pets or people. The recipes included here make a solution that is roughly 2 per cent lavender oil.
