Spiders are known for not liking lavender. Containing linalool and linalyl acetate, two compounds that repel spiders and other insects, lavender is a natural deterrent for spiders. When a spider encounters lavender, it doesn’t like the scent and is less likely to venture any closer. The plants won’t kill spiders, but it will deter them. It will also prevent them from making a nest in your home. That’s why it’s a good idea to place lavender plants around your front and back doors as well as around windows or any other gaps.
When planting lavender bushes as a spider repellent, you can plant them in your garden or a container on your porch. However, these plants need a lot of sunlight, so if you have a covered porch, they won’t do well there. Instead, you can try to place them along a walking path that leads to your door. The more lavender plants, the greater the deterrent effect — so the more, the better.
