So... What's an Earwig?

Adult earwigs have long slender bodies that are reddish-brown to black in color. The pincers at the end of their bodies are longer in males than in females. These pincers are probably one of the best ways to identify earwigs.



Their bodies are flat which makes it easy for them to get in and out of tight spots. Adults can be foul-smelling and may release a yellowish-brown secretion from their scent glands.


Young earwigs have shorter bodies, a lighter greenish or whitish color, and do not have wings. Eggs are cream colored and roundish in shape.





Reproduction Patterns of Earwigs

In the spring, the adult female earwig deposits about 50 eggs in a cavity in the soil. The female has been known to lay up to 300 eggs at one time in clusters in several cavities.


She will fiercely protect her eggs, and will protect her babies after they hatch until they have gone through their first molt. Then these nymphs embark on their own.


After going through several instars, they become adults. Both adults and eggs overwinter in the soil, and there is usually just one generation per year.





Earwig's Habitat

Earwigs prefer to live outside, although they may be brought inside accidentally through bags, newspapers, cut flowers, and other means. They may also enter a home on their own through a crack, especially during hot, dry weather, searching for refuge in cool basements and crawl spaces.


Earwigs scurry around at night, searching for other insects or plants on which to feed. They are often attracted to lights and can be found in large groups at night under bright outdoor lights.


During daytime hours, they prefer to hide under trash, under boards, in mulch, and just about any concealed place that is cool and moist.


Diatomaceous Earth

They do not reproduce indoors, preferring instead to lay their eggs deep in the soil. Using a product such as Safer® Brand Ant and Crawling Insect Killer can help you eliminate your earwig problem. Since diatomaceous earth is a mechanical killer, insects can not develop an immunity to diatomaceous earth. Click on the above link to view the product page where you can find application tips.
