Tea tree oil is used as a cleaning agent and a beauty product because of its antibacterial and antifungal properties. But what about pests, particularly spiders? You may have heard of using tea tree oil for spiders as a cheap and effective spider control DIY remedy.

After all, tea tree oil can work for other insects, so why not arachnids? Can you use this very popular oil for arachnids? Does it even work?

In this guide, we look to dispel fact from myth. There are many essential oil enthusiasts that use certain oils to repel bugs. Spiders of any type are notoriously difficult to get rid of, so let’s find out if this cost-effective remedy will actually work!

Does Tea Tree Oil Repel Spiders?

Like lavender and lemon oil, tea tree or melaleuca oil works against spiders because it is basically an essential oil. It has the scent and composition that spiders just happen to be repelled by.

According to a 2010 study on the insecticidal activities of essential oils, essential oils have monoterpenoids, substances that naturally repel quite a number of bugs. These monoterpenoids are also fumigants which makes them deadly to pests. And because of this, they’re treated as a main ingredient in a lot the pesticides that we buy in our local supermarkets.

Another study from India supports this, saying that pesticides based on plant essential oils are clearly effective when dealing with pests.

Additionally, another key reason why tea tree oil works against spiders is the fact that they have sensory organs that are different from ours. They smell and taste through their legs. So spraying a good amount of the oil into the surfaces that spiders walk on could repel them because they hate the smell and taste of the oil.
