Earwigs are small, brown insects that can be found in gardens, yards, and homes. They are known for their pincer-like appendages, which they use for defense and hunting. While earwigs are not harmful to humans, they can be a nuisance when they infest gardens or homes. Many people are looking for natural ways to repel earwigs, and one of the potential solutions is green tea.

What Are Earwigs?

Earwigs are insects that belong to the order Dermaptera. They have long, flat bodies that can be up to an inch long. Earwigs have two pairs of wings, but they rarely fly. Instead, they use their wings to glide short distances. Earwigs are attracted to moist environments and can often be found under rocks, in plant debris, and in other dark places. They are active at night and feed on other insects, plants, and decaying organic matter.

While earwigs do not pose a threat to humans, they can cause damage to gardens and crops. They feed on fruits, vegetables, and flowers, which can result in significant losses for farmers and gardeners.

What is Green Tea?

Green tea is a type of tea that is made from the leaves of the Camellia sinensis plant. It is a popular beverage in many parts of the world and is known for its health benefits. Green tea contains antioxidants and other compounds that have been shown to have anti-inflammatory and anti-cancer properties.

In addition to its health benefits, green tea has also been studied as a potential insect repellent. Some research suggests that the compounds in green tea may repel certain types of insects, including earwigs.

Scientific Evidence

Several studies have been conducted on the effectiveness of green tea as an insect repellent. One study published in the Journal of Economic Entomology found that green tea extract was effective at repelling several species of insects, including mosquitoes and houseflies. Another study published in the Journal of Agricultural and Food Chemistry found that a compound found in green tea called EGCG was effective at repelling ticks.

While there is limited research specifically on green tea’s effectiveness at repelling earwigs, these studies suggest that it may be a promising natural solution for those looking to keep pests at bay.

Use of Green Tea as an Earwig Repellent

If you want to try using green tea as an earwig repellent, there are several methods you can use:

  • Spray a mixture of brewed green tea and water around areas where earwigs are present.
  • Soak cotton balls in brewed green tea and place them in areas where earwigs are likely to hide.
  • Add used green tea bags to your compost pile to repel earwigs from your garden.

To maximize the effectiveness of green tea as a repellent, it’s important to use fresh brewed tea rather than bottled or pre-packaged teas. You should also reapply the solution regularly to ensure that it remains effective.

Other Natural Repellents

In addition to green tea, there are other natural methods for repelling earwigs. These include:

  • Diatomaceous earth
  • Citrus oil
  • Cedar oil
  • Lavender oil

While these methods may be effective at repelling earwigs, they may not be as practical or readily available as green tea.


In conclusion, while there is limited research specifically on green tea’s effectiveness at repelling earwigs, there is some evidence to suggest that it may be effective at repelling certain types of insects. If you’re looking for a natural way to keep pests out of your home or garden, using green tea may be worth trying out.

However, it’s important to remember that while green tea may be effective at repelling some insects, it may not work for all types of pests. Additionally, if you have a severe infestation of earwigs or other pests, you may need to seek professional pest control services.
