The Popular Garden Flower That Will Expel Spiders From Your Home

Spiders may not pose a significant threat to humans, but their sudden appearance in your home can often leave you startled and screaming in fear. While most spiders usually flee instead of biting, some species, like the black widow or brown recluse spider, can be venomous and pose a danger to your health. To prevent spiders from entering your home and causing you anxiety, consider keeping a lavender plant indoors as it is known to repel these pesky pests.

If you or someone in your household has a fear of spiders, it’s best to take precautions to keep them away. According to the Cleveland Clinic, arachnophobia, or the fear of spiders, is one of the most common phobias, affecting 3 to 5 percent of people.

There are several natural remedies that you can use to keep spiders at bay, including essential oils, spices like cinnamon and vinegar, and even rolling tobacco. However, using a lavender plant is an excellent way to repel spiders while creating a calming and relaxing atmosphere in your home.

Spiders and lavender

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.

If you already have spiders in your home and want to shoo them away by using lavender plants, place the plants in areas where you have seen spiders. Lavender plants grow nicely indoors as long as they get enough sunlight. They typically need at least 3 to 4 hours of direct sunlight daily.

Alternatively, you can use lavender essential oil in a diffuser to let the scent permeate through the air. Another way to use lavender oil is to mix 10 drops of it with water in a spray bottle. This will create an easy-to-use spray for areas where spiders are most active. An added boost is that, unlike chemical pesticides, lavender won’t harm the environment. Plus, lavender’s calming scent has a positive impact on our mood and well-being. Yet, while lavender plants are non-toxic to humans and an eco-friendly solution, they can be toxic to dogs and cats,  so you may want to avoid keeping the plants inside if you have pets.
