Comprehensive Guide to Identifying and Managing Earwigs in Your Garden

Do you remember being a kid and feeling a sense of unease when you spotted an earwig scurrying about? This common insect, known for its pincer-like appendages, can be both a beneficial ally in your garden and a pesky nuisance.

In this comprehensive guide, we will delve into the world of earwigs to help you better understand how to identify and manage them in your garden effectively.

Getting to Know Earwigs

Table of Contents

Earwigs belong to the order Dermaptera, which boasts around 2,000 species worldwide. In the US, there are approximately 22 species, with the common or European earwig (Forficula auricularia) being the most prevalent.

Characterized by their shiny reddish-brown bodies, tan legs, and short wings, earwigs are known to feed on a variety of plant materials and insects. While they can be helpful in controlling pests like aphids and insect larvae, they can also cause damage to seedlings, fruits, and flowers.

Popular Earwig Species:

Common or European earwig (Forficula auricularia)
Ringlegged earwig (Euborellia annulipes)
Tawny, shore, or striped earwig (Labidura riparia)

While the common belief that earwigs crawl into people’s ears is a myth, these insects do have a fascinating history, with the first reported outbreak in North America dating back to 1911 in Rhode Island.

Identifying Earwigs

Earwigs are easily recognizable by their distinctive appearance. These insects measure around half to five eighths of an inch in length, with tough, flat bodies, and pincer-like appendages at their rear.

Adult earwigs have short leathery wings, while nymphs resemble smaller versions of adults with pale gray to light brown bodies. Additionally, female earwigs exhibit maternal behavior by guarding and tending to their eggs.

Biology and Behavior

Earwigs typically mate in the fall, with females laying clusters of eggs in the spring. The nymphs go through multiple instar stages before emerging from the nest to forage for food. These insects are primarily active at night, seeking shelter in dark and moist areas during the day.

Naturally, earwigs feed on decaying organic matter, insects, and plants, making them vital components of the ecosystem. However, they can become problematic when they start causing damage to garden plants.

Monitoring and Detecting Earwigs

Monitoring earwig populations in your garden is crucial to determine the extent of the infestation. Common signs of earwig damage include irregular holes in leaves, chewed fruits, and damaged flowers.

To monitor earwigs, consider setting up traps using materials like newspaper, cardboard rolls, or sticky tape. Additionally, inspect plants known to be vulnerable to earwig feeding, such as lettuce, corn, and berries.

Effective Control Methods

Controlling earwig populations in your garden can be achieved through a combination of cultural, physical, biological, and organic pesticides. Integrated pest management (IPM) strategies can help you effectively manage earwigs while minimizing negative impacts on beneficial insects and the environment.

Cultural Control

Remove plant debris and decaying material regularly.
Early cultivation of the garden helps expose earwig eggs to adverse conditions.
Start seedlings early to mitigate damage from emerging nymphs.

Physical Control

Use homemade traps or commercial earwig traps to capture these insects.
Apply barriers, such as sticky tape, around plants to prevent earwigs from reaching them.
Handpick earwigs and dispose of them in soapy water.

Biological Control

Encourage natural predators like birds, toads, and ground beetles.
Beneficial insects like tachinid flies can parasitize earwigs in the garden.
Certain fungi species can infect and control earwig populations.

Organic Pesticides

Use organic products labeled for earwig control, such as Gargoil Insect, Mite, and Disease Control.
Pyrethrin and spinosad-based sprays can effectively target earwigs while minimizing harm to beneficial insects.
Apply diatomaceous earth products around plants to deter earwigs from feeding.

When to Consider Chemical Pesticides

While chemical pesticides should be a last resort, some options are available if earwig populations become overwhelming. Products such as carbaryl, chlorpyrifos, and imidacloprid can provide control but should be used sparingly and with caution.

Embracing Nature’s Balance

Despite their unsettling appearance, earwigs play an essential role in the ecosystem. By employing integrated pest management strategies and combining cultural, physical, and biological controls, you can effectively manage earwig populations in your garden without resorting to harmful chemicals.

While these insects may evoke fear or dislike in some individuals, understanding their behavior and implementing sustainable control methods can help create a harmonious garden environment where pests are managed efficiently and responsibly.
