What Exactly Are Earwigs?
Earwigs, known for their distinctive pincers and dark brown bodies, are nocturnal insects that often cause significant damage to plants, including dahlias. These pests feed on leaves, petals, and other plant material, leaving behind chewed edges and small holes.
Earwigs are about an inch long, and their pincers, located at the rear, are used for defense and capturing prey. Despite their intimidating appearance, they are generally harmless to humans.
Earwigs are attracted to dahlias and other susceptible plants due to the moisture and shelter they provide. Dahlias, with their dense foliage and vibrant blooms, create an ideal habitat for earwigs. These insects thrive in dark, damp environments, often hiding under mulch, leaf litter, and other garden debris during the day. They are particularly drawn to gardens with ample moisture and plenty of hiding places.
In addition to feeding on dahlias, earwigs also consume aphids and other small insects, which can be beneficial in small numbers. However, a large population of earwigs can quickly become a problem, causing noticeable damage to your plants.
Identifying Earwig Damage on Dahlias
Earwig damage on dahlias is often visible as chewed leaves and petals. These pests feed primarily at night, leaving behind irregular holes and jagged edges on the foliage and flowers. The damage can be particularly noticeable on new growth and tender seedlings, making dahlias and other susceptible plants look tattered and unhealthy.
These are the signs of earwig damage:
Chewed leaves and petals: Look for leaves with irregular, ragged holes and petals with chewed edges. The damage is usually more prevalent in the lower parts of the plant, where earwigs hide during the day.
Nibbled seedlings: Earwigs are notorious for feeding on young, tender plants. If you notice seedlings with significant damage, earwigs might be the culprits.
Presence of earwigs: Spotting earwigs around the base of your dahlias or under garden debris is a clear sign that they are present and active.
Difference between earwig damage and damage caused by other pests
Earwigs vs. slugs and snails: While earwig damage can resemble that of slugs and snails, there are key differences. Slugs and snails leave a trail of slime and tend to cause more extensive damage by eating larger portions of leaves and flowers.
Earwig damage, on the other hand, is typically smaller and more irregular. Additionally, earwigs do not leave a slimy residue.
Earwigs vs. aphids: Aphids suck the sap from plants, causing leaves to curl and distort rather than chew holes in them. If your dahlias have misshapen or discolored leaves, aphids might be the problem instead of earwigs.
Preventive Measures
Implementing preventive measures will keep earwigs away from your dahlias. Start by creating an environment that is less attractive to these pests.
Reduce moisture and debris
Clear the area around dahlias: Keep the area around your dahlias free of leaves, mulch, and decaying organic matter. Earwigs thrive in dark, damp environments, so removing potential hiding places will make your garden less inviting to them.
Ensure proper drainage: Good drainage is essential to reduce moisture levels in the soil around your plants. Water your dahlias deeply but less frequently to keep the surface of the soil dry. Fix any leaks or drainage issues to prevent standing water, which attracts earwigs and other pests.
Encourage natural predators
Attract birds: Birds are natural predators of earwigs and can help keep their populations in check. To attract birds to your garden, provide year-round water sources, such as birdbaths, and plant a diverse selection of native plants that offer food and shelter.
Birdhouses or dead tree cavities can also provide nesting sites.
Other predators: Besides birds, other natural predators like ground beetles and spiders can help control earwig populations. Maintain a healthy garden ecosystem that supports these beneficial insects for an effective, chemical-free way to manage earwigs.
Natural Control Methods
Using natural control methods can keep earwigs away from your dahlias without resorting to harsh chemicals. Here are some tried-and-true techniques to protect your plants.
Vaseline
Smear Vaseline on the stems of your dahlias to create a barrier that earwigs cannot cross. Apply a thin layer of Vaseline starting from the base of the stem and working your way up.
This method works by preventing earwigs from climbing up to the leaves and flowers, keeping your dahlias safe from damage.
Organza bags
Organza bags are an excellent way to protect dahlia blooms from earwigs. These breathable bags allow sunlight, air, and moisture to reach the flowers while keeping pests out.
Simply place the bag over the bloom and secure it with the drawstring at the base of the petals. This method is particularly effective for larger dahlia varieties and can be left in place until the earwig threat has passed.
Paper traps
Rolled-up newspaper or cardboard makes simple and effective earwig traps. Place these paper traps near the base of your dahlia plants or in other areas where you have seen earwig activity. Earwigs will seek shelter in the traps overnight.
In the morning, collect the traps and dispose of them in soapy water to kill the earwigs. Repeat this process regularly to reduce the earwig population in your garden.
Homemade and Organic Solutions
Using homemade and organic solutions can effectively control earwigs on your dahlias without harming the environment. Here are two effective methods to try:
Soy sauce traps
Take a small plastic container and mix equal parts soy sauce and vegetable oil. The soy sauce attracts the earwigs with its strong odor, while the vegetable oil traps and drowns them.
Poke small holes (about 0.25 inches in diameter) in the lid of the container. These holes should be large enough for earwigs to enter.
Bury the container at ground level near your dahlias, ensuring the holes are at the surface. The earwigs will crawl into the container, attracted by the soy sauce, and drown in the oil.
Check the traps regularly and dispose of the dead earwigs. Refill and reset the traps as needed to continue controlling the earwig population.
Diatomaceous earth
Use food-grade diatomaceous earth, which is safe for use around plants and animals.
Sprinkle a thin layer of diatomaceous earth around the base of your dahlia plants and in any areas where you've seen earwig activity. Diatomaceous earth works by dehydrating and killing earwigs when they come into contact with the fine powder.
Diatomaceous earth loses its effectiveness when wet, so reapply after rain or heavy watering to maintain its pest control properties.
