Earwigs are the last thing any gardener wants to see crawling through their plants. With a healthy appetite for foliage, flowers, and even fruits, these pests can quickly turn a beautiful garden into a patch of chewed-up leaves. While they occasionally help by eating other pests like slugs and snails, an earwig infestation can be destructive if left unchecked. Here’s how to identify earwigs and keep them from taking over your garden.
What Are Earwigs?
Earwigs are small, elongated insects known for their rear pincers, which they use for defense and hunting. They are nocturnal, hiding in dark, moist places during the day and coming out at night to search for food.
These pests thrive in gardens because of the moisture, shade, and abundance of food. While they’ll eat just about anything, some of their favorite garden snacks include squash, potatoes, dahlias, marigolds, and beans. They can also devour seedlings before they even get a chance to bloom.
Earwigs multiply quickly, with females laying up to 30 eggs twice a year. This rapid reproduction can lead to a garden infestation in no time.
Signs of an Earwig Problem
It can be tricky to spot earwigs since they only come out at night, but here’s what to look for:
How to Prevent Earwigs in Your Garden
Keep Your Garden Clean
Earwigs are attracted to decomposing plant material, so regular cleanup is essential.
Use Dry Gravel or Mulch
Since earwigs love moisture, adding dry gravel or coarse mulch around your plants can deter them. They dislike crawling through rough, dry materials, making your garden less inviting.
Eliminate Excess Light
Earwigs are drawn to bright lights at night. Reduce or eliminate outdoor lighting near your garden to avoid attracting them. If lighting is necessary, consider using motion-activated or yellow-toned bulbs that are less appealing to insects.
By keeping your garden clean, reducing moisture, and limiting light sources, you can make your outdoor space far less inviting to earwigs. With these tips, you’ll be able to protect your plants and enjoy a thriving, earwig-free garden.
