Earwigs are a common garden pest that can wreak havoc on plants and crops. These insects are known for their pincers that they use for defense and capturing prey. While they do not pose a significant threat to humans, the presence of earwigs can be alarming and even frightening for some individuals. This article aims to explore the effectiveness of baking soda in repelling earwigs, as well as other natural remedies for pest control.

What is baking soda?

Baking soda, also known as sodium bicarbonate, is a white crystalline powder that is commonly used in cooking, cleaning, and personal hygiene products. Its chemical composition consists of one sodium ion, one hydrogen ion, one carbon ion, and three oxygen ions. Baking soda has numerous household uses including deodorizing, removing stains, and even controlling pests.

Can baking soda repel earwigs?

There is limited scientific research on the effectiveness of baking soda as a method of repelling earwigs. However, there are anecdotal reports from homeowners who claim that sprinkling baking soda around their homes and gardens has helped to reduce the presence of earwigs. Some theories suggest that the alkaline nature of baking soda may disrupt the pH balance of an earwig’s body, causing them to seek out a more hospitable environment.

How to use baking soda to repel earwigs

To use baking soda as a method of repelling earwigs, follow these steps:

  1. Clean the area where earwigs are present.
  2. Fill a shaker or sifter with baking soda.
  3. Sprinkle the baking soda around the perimeter of your home or garden.
  4. Repeat every few days or after rain or watering.

It is important to note that while baking soda is considered safe for humans and pets, it can irritate the eyes and respiratory system if inhaled. Be sure to wear gloves and a mask when handling baking soda.

Other natural ways to repel earwigs

In addition to baking soda, there are several other natural remedies for repelling earwigs. Essential oils such as peppermint, lavender, and tea tree oil have been found to be effective in deterring insects. Diatomaceous earth is also a popular method of pest control as it can dehydrate and kill insects upon contact. Citrus peels such as lemon or orange can also be used to repel earwigs.


While there is limited scientific evidence on the effectiveness of baking soda in repelling earwigs, it may be worth trying as a natural pest control method. However, it is important to note that there are other natural remedies that have been found to be equally effective. Using natural methods of pest control not only promotes a healthy environment but also reduces exposure to harmful chemicals.
