Earwigs and Holes:
What Size Can They Fit Through?

Earwigs are common insects that are known for their unique appearance, including their elongated bodies and pincers. These insects are often found in gardens and other outdoor spaces, where they can be beneficial by feeding on pests and decomposing organic matter. However, earwigs can also be a nuisance when they invade homes, sometimes squeezing through small holes and cracks to gain entry. In this article, we will explore the size of holes that earwigs can fit through and offer tips on how to keep them out of your home.

How Small Can Earwigs Squeeze Through?

Earwigs are quite agile and can squeeze through surprisingly small openings. Generally, earwigs can fit through any hole or crack that is wider than their bodies, which can vary in length depending on the species. The common European earwig (Forficula auricularia) typically measures between 0.5 to 1 inch in length, while the striped earwig (Labidura riparia) can grow up to 1.25 inches long.

Despite their relatively large size, earwigs are able to contort their bodies to fit through tight spaces. They are also able to use their pincers to grip onto surfaces as they move through small openings, making it easier for them to navigate through narrow gaps.

How Can You Prevent Earwigs from Entering Your Home?

Preventing earwigs from entering your home starts with sealing off potential entry points. This includes filling in gaps around windows and doors, repairing damaged screens, and sealing cracks in the foundation or walls of your home.

It is also important to keep your home clean and tidy, as earwigs are attracted to damp environments and organic matter. This means fixing leaky pipes or faucets, removing piles of leaves or debris from around your home’s perimeter, and cleaning up spills or messes promptly.

If you are still experiencing problems with earwigs despite taking preventive measures, you may want to consider using insecticides or contacting a pest control professional for assistance.

Frequently Asked Questions

How do I know if I have an earwig infestation?

Earwigs are nocturnal insects, which means they are most active at night. If you suspect that you have an earwig infestation, look for signs of their presence in areas where they are likely to congregate, such as under rocks or in garden beds. You may also see them inside your home, particularly in damp or dark areas like basements or bathrooms.

Can earwigs cause harm to humans?

Although earwigs have a reputation for crawling into human ears, this is a rare occurrence and is not typically cause for concern. Earwigs do not pose a direct threat to humans and are not known to transmit diseases.

How can I get rid of earwigs without using pesticides?

If you prefer not to use pesticides, there are several non-toxic methods for getting rid of earwigs. One option is to set up traps using rolled-up newspaper or cardboard tubes filled with a damp paper towel. Earwigs will often crawl into these traps seeking shelter and can be disposed of once they are trapped. You can also try spraying a mixture of equal parts water and white vinegar around areas where earwigs are present, as the acidic scent may repel them.

In conclusion, while earwigs may seem intimidating due to their unique appearance and ability to squeeze through small holes, there are ways to prevent them from entering your home. By sealing off potential entry points and keeping your home clean and tidy, you can reduce the likelihood of an infestation. If you do encounter problems with earwigs despite taking preventative measures, there are both chemical and non-toxic options available for getting rid of them.
