About Earwigs and Damage Symptoms

Earwigs are small, brown insects that have a pair of pincers at the end of their abdomen. They are mostly nocturnal and hide in moist, dark places during the day, such as under mulch, leaves, stones, or bark. They feed on a variety of organic matter, including plants, flowers, fruits, moss, and other insects.

Earwigs can cause damage to gardens by chewing holes in leaves, petals, buds, and fruits. They can also stunt the growth of young seedlings by feeding on their roots. Earwigs are not harmful to humans and pets, but they can pinch with their pincers if disturbed.

To make this spray, you will need some fresh or dried catnip, water, and a pot. Boil some water and add the catnip to it. Let it steep for about 15 minutes, and then strain the liquid. Add some dish soap to it and pour it into a spray bottle. Spray the plants and soil with this solution every few days or as needed.

To make this bait, you will need some cornmeal, water, and a shallow container (such as a plastic lid or a jar lid). Mix some cornmeal with water to form a paste and place it in the container. Put the container near the plants where you see earwig activity at night. The earwigs will crawl into the container to eat the cornmeal and die.
