Earwigs are one of the most common garden pests, often causing damage to plants, fruits, and vegetables with their sharp pincers. While they are not typically harmful to humans, their presence can wreak havoc on your garden, leaving behind unsightly damage. If you’ve noticed earwigs in your garden or on your plants, it’s essential to act quickly to protect your garden. Luckily, there are a variety of ways to get rid of earwigs and prevent them from coming back. In this article, we will walk you through 12 effective steps to control earwig populations and safeguard your garden using natural methods.
1. Identify the Problem: What Are Earwigs?
The first step in dealing with any pest issue is identifying the problem correctly. Earwigs are small, brown insects with pincers on their rear end, which they use for defense and hunting. They are nocturnal creatures, which means they come out at night and hide in damp, dark places during the day. These insects tend to feed on decaying organic matter, but they can also cause damage to living plants, fruits, and flowers by eating the leaves, flowers, and soft stems.
Earwigs are often found in garden areas that are moist and provide hiding spots, such as under rocks, leaves, and garden debris. If you’ve observed ragged or chewed leaves on your plants, it’s a good sign that earwigs might be at work.
2. Remove Hiding Spots and Debris
Earwigs thrive in dark, moist environments. One of the simplest yet most effective ways to get rid of earwigs is by removing their hiding spots. Clear away piles of leaves, grass clippings, mulch, and any other debris that could serve as a shelter for these pests. By making your garden less hospitable to them, you’ll significantly reduce their chances of taking up residence.
When you clean up, be sure to check under rocks, garden pots, and other structures where earwigs might be hiding. Removing such shelter not only helps eliminate existing infestations but also prevents new ones from settling in.
3. Set Beer Traps
Beer traps are one of the most popular and effective ways to attract and trap earwigs. Earwigs are drawn to the scent of beer, and they will crawl into a container and fall in. To create a beer trap, simply bury a shallow container, such as a small bowl or cup, in the soil at ground level. Fill it with beer, leaving the rim slightly above the soil surface.
The earwigs will be attracted to the beer and will drown in the liquid. Make sure to check and replace the beer regularly for optimal results. Beer traps are an excellent way to reduce earwig numbers without using harmful chemicals.
4. Create Paper Roll Traps
Another simple and natural way to trap earwigs is by using damp newspaper or cardboard rolls. Simply take a piece of damp newspaper or roll up cardboard and place it near the affected plants in your garden. Earwigs love dark, moist environments, so they will crawl into the roll to hide. You can then collect the paper rolls the next morning and dispose of the trapped earwigs.
This method is both inexpensive and environmentally friendly, making it a great option for gardeners looking to avoid chemicals in their gardens.
5. Apply Diatomaceous Earth
Diatomaceous earth (DE) is a natural, non-toxic substance that works as an effective pest control solution. DE consists of the fossilized remains of tiny marine organisms and is harmless to humans and pets but deadly to insects with exoskeletons, such as earwigs. When earwigs come into contact with diatomaceous earth, it dehydrates their bodies and causes them to die.
Sprinkle a thin layer of food-grade diatomaceous earth around the base of your plants or on top of the soil. Be sure to reapply it after watering or rainfall. This method is particularly useful for controlling a variety of garden pests, including earwigs.
6. Use Neem Oil Spray
Neem oil is a natural pesticide made from the seeds of the neem tree. It works by disrupting the reproductive and feeding processes of insects. When applied to earwigs, neem oil interferes with their ability to feed and reproduce, helping to reduce their population. Neem oil also repels other pests in your garden, making it a multi-purpose solution.
To use neem oil, mix it with water according to the instructions on the bottle and spray it directly onto your plants, focusing on the affected areas. Repeat this process every few days or after rainfall to maintain its effectiveness.
7. Encourage Beneficial Predators
One of the most sustainable ways to control earwig populations is by attracting beneficial predators to your garden. Birds, frogs, toads, and predatory beetles are all natural enemies of earwigs. By creating an environment that encourages these helpful creatures to visit your garden, you can naturally control earwig numbers.
You can attract birds by placing birdhouses or feeders in your garden. Frogs and toads are drawn to damp areas, so incorporating a small pond or water feature may encourage them to visit. Additionally, predatory beetles, such as ground beetles, can help keep earwigs under control by hunting them in the soil.
8. Install Copper Tape Around Plants
Copper tape is often used as a barrier for slugs and snails, but it can also be effective against earwigs. When earwigs come into contact with copper, it creates a small electrical charge that irritates their bodies, deterring them from climbing plants or garden beds. This simple barrier can help protect your plants from earwig damage.
To use copper tape, apply it around the base of your plants or garden beds. You can also place it around containers or pots to prevent earwigs from entering.
9. Spray with Garlic or Hot Pepper Solution
Garlic and hot peppers are both natural repellents for many pests, including earwigs. You can make your own homemade spray by blending garlic cloves or hot peppers with water. The strong odor of garlic or the heat from the peppers will deter earwigs from feeding on your plants.
To make the spray, blend 10-12 garlic cloves or a couple of hot peppers with a quart of water. Let the mixture sit for a few hours, then strain and pour it into a spray bottle. Spray it directly on the plants that are being affected by earwigs, and repeat every few days.
10. Water Your Garden Early in the Day
Earwigs are nocturnal creatures, and they are most active in damp conditions. By watering your garden early in the morning, you can avoid creating a moist environment in the evening, which is when earwigs are most likely to emerge. Early watering helps ensure the soil dries out by nightfall, making it less attractive to earwigs and other pests.
11. Use Mulch Sparingly
While mulch can be great for retaining moisture and improving soil quality, it can also create the perfect hiding space for earwigs. If you mulch your garden, be careful not to pile it too thickly around your plants, as it can provide shelter for earwigs and other pests.
Consider using mulch alternatives like straw or pine needles, which are less likely to retain moisture and create an ideal hiding spot for earwigs.
12. Manually Remove Earwigs
If you’ve tried all of the above methods and still have earwigs in your garden, you may need to remove them by hand. You can use a vacuum cleaner to suck up earwigs and their eggs, or simply pick them off your plants and drop them into a container of soapy water. While this method may take more time and effort, it can be effective for small infestations.
Conclusion
Earwigs may seem like a minor garden nuisance, but if left unchecked, they can cause significant damage to your plants and vegetables. Fortunately, with the right combination of natural pest control techniques, you can keep earwig populations under control and protect your garden. By removing hiding spots, setting traps, and encouraging natural predators, you can prevent earwigs from ruining your hard work.
