Earwigs are one of the most common pests that homeowners have to deal with. These small, brown insects have a distinctive pair of pincers on their rear end that can be intimidating to some people. They are nocturnal creatures that tend to hide in dark, damp places during the day and come out at night to feed on plants and other insects.

Copper, on the other hand, is a versatile metal that has many uses in our daily lives. It conducts electricity and heat well, making it an ideal material for wiring and plumbing. It is also resistant to rust and corrosion, which makes it a popular choice for outdoor decorations and household items.

The purpose of this article is to explore whether copper can effectively repel earwigs from your home or garden. We will examine the physical characteristics and habits of earwigs, as well as the properties of copper that may make it an effective deterrent. We will also look at scientific studies and personal experiences to determine if copper is a viable solution for dealing with earwig infestations.

Earwig Behavior

Earwigs are small insects that range in size from 5 to 25 millimeters long. They have a flat body shape and a pair of pincers on their rear end that they use for defense and mating. Earwigs are nocturnal creatures that prefer dark, damp environments such as under rocks, logs, or mulch.

Earwigs are considered pests because they feed on plants and can cause damage to gardens and crops. They may also invade homes looking for shelter or food. While earwigs do not pose a threat to humans or pets, their presence can be unsightly and unsettling.

Copper Properties

Copper is a soft, malleable metal with a reddish-orange color. It is an excellent conductor of electricity and heat, which makes it ideal for electrical wiring and plumbing applications. Copper is also resistant to corrosion and has antimicrobial properties that make it useful in medical equipment.

The antimicrobial properties of copper may also repel insects such as earwigs. Studies have shown that copper surfaces can kill bacteria, viruses, and fungi on contact. This same property may make copper an effective insecticide.

Evidence for Copper’s Effectiveness Against Earwigs

Many people have reported success in using copper to repel earwigs from their homes or gardens. Personal anecdotes suggest that placing copper tape or mesh around the perimeter of a garden bed or along the foundation of a house can prevent earwigs from crossing over.

Scientific studies have also been conducted to test the efficacy of copper against earwigs. One study found that copper mesh placed around tomato plants reduced the number of earwig damage by 50%. Another study found that earwigs were less likely to cross over copper barriers than plastic barriers.

Other Methods for Repelling Earwigs

While copper may be an effective solution for repelling earwigs, there are other methods available as well. Natural remedies such as diatomaceous earth or essential oils like lavender or peppermint have been known to repel insects without harming them. Chemical treatments such as insecticides or baits are also available on the market.

It’s important to weigh the advantages and disadvantages of each method before choosing one. Natural remedies may be safer for pets and children but may not be as effective as chemical treatments. Chemical treatments may be more potent but can pose health risks if not used properly.


In conclusion, copper has shown promise in repelling earwigs from gardens and homes. Its antimicrobial properties may also make it an effective insecticide against other pests. However, more research is needed to determine its long-term effectiveness and whether it’s a practical solution for large-scale infestations.

If you’re dealing with an earwig infestation, consider trying copper tape or mesh around your garden or home’s foundation. You can also explore natural remedies or chemical treatments available on the market. Remember to take precautions when using chemical treatments and seek professional help if needed.
