Earwigs are a common pest that can be found in gardens, homes, and other outdoor spaces. These insects are known for their pincers and the foul odor they emit when threatened. Many people are eager to find solutions to repel earwigs, and one potential solution is Benzoin. In this article, we will explore the effectiveness of Benzoin in repelling earwigs and how to use it properly.

What is Benzoin?

Benzoin is a resin that is extracted from the bark of trees in the Styrax family. It has been used for centuries in traditional medicine and as an incense in religious ceremonies. Today, Benzoin is used in a variety of industries, including cosmetics, food flavoring, and pharmaceuticals.

There are different types of Benzoin, including Sumatran and Siam. Sumatran Benzoin is known for its sweet, vanilla-like scent and is commonly used in perfumes and candles. Siam Benzoin has a more complex scent with hints of cinnamon and is often used in incense.


Earwigs are insects that belong to the order Dermaptera. They have elongated bodies with two pairs of wings and pincers on their abdomen. Earwigs are nocturnal and prefer dark, moist environments such as under rocks or in soil. They are omnivores and feed on both plants and insects.

Earwigs have a unique life cycle that includes four stages: egg, nymph, adult, and molting. The nymph stage can last anywhere from 20 days to several months depending on environmental conditions. Earwigs can lay up to 80 eggs at once, which hatch into nymphs within a few days.

Can Benzoin Repel Earwigs?

Previous studies have shown that Benzoin can be effective in repelling insects such as mosquitoes and ticks. However, there is limited research on the effectiveness of Benzoin specifically for repelling earwigs.

In an experimental study conducted by researchers at Oregon State University, Benzoin was found to be moderately effective in repelling earwigs. The study involved applying different concentrations of Benzoin to filter paper discs and placing them in petri dishes with earwigs. The results showed that higher concentrations of Benzoin were more effective at repelling earwigs than lower concentrations.

How to Use Benzoin to Repel Earwigs

There are several methods to use Benzoin as an insect repellent for earwigs. One method is to mix a few drops of Benzoin essential oil with water in a spray bottle and spray it around areas where earwigs are present such as garden beds or around the perimeter of your home.

Another method is to apply a small amount of Benzoin resin onto cotton balls or scraps of fabric and place them near areas where earwigs are present. The scent of the resin will help repel earwigs.

When using Benzoin, it’s important to take safety precautions such as wearing gloves when handling the resin or essential oil. It’s also important to keep Benzoin away from children and pets as it can be toxic if ingested.

To prevent earwig infestations, it’s important to keep your home and garden clean and dry. This includes removing debris from your yard, fixing any leaks or moisture issues, and sealing cracks or gaps around windows and doors.


In conclusion, while there is limited research on the effectiveness of Benzoin specifically for repelling earwigs, experimental studies have shown it to be moderately effective. If you’re looking for a natural solution to repel earwigs, Benzoin may be worth exploring further. Just remember to use it safely and take preventative measures to avoid infestations.
