How to Get Rid of Leatherjackets (Natural & Organic Methods)

By Sabrina Wilson / July 27, 2022

The larvae of some species of learfish are called "leatherjackets" because of their hard, leathery skin. These voracious predators can cause significant damage to crops, yards, and gardens. Some species are considered serious agricultural pests. In the United Kingdom, the common green leatherjacket (Cornu aspersum) is considered the most destructive garden pest. It is a small, brownish-black beetle with a hard, leathery body. The adult beetle can fly and is attracted to lights. It lays its eggs on the ground in late summer or early fall. The larvae hatch in late fall and begin feeding on plant roots. They continue to feed through the winter, causing considerable damage to crops and other plants. In the spring, they pupate and emerge as adults in early summer. There is only one generation per year.

Leatherjackets are particularly damaging to lawns. The larvae feed on the roots of grasses, causing the grass to wilt and die. Large areas of lawn can be destroyed by leatherjackets in a single season. In addition to damage to crops and lawns, leatherjackets can also damage trees and shrubs. The larval stage is the most damaging, but the adults can also cause damage by feeding on leaves and flowers.

Leatherjackets can be controlled with cultural, mechanical, and chemical methods. Cultural methods include maintaining healthy turf and plants, and removing debris where the adults lay their eggs. Mechanical methods include hand-picking adults and larvae, and using traps. Chemical methods include the use of insecticides. Insecticides should be used only as a last resort, and only when other methods have failed.

As the demand for more environmentally friendly and sustainable methods of living increases, so does the popularity of natural or organic methods for getting rid of leatherjackets. These methods are preferable for a number of reasons: they are often more effective at killing leatherjackets than chemical methods, they are better for the environment, and they are often more affordable.

Natural or organic methods of getting rid of leatherjackets typically involve using predators or parasites to kill the larvae. Common predators used include beetles, wasps, and flies. These predators are often released into an area where leatherjackets are present, and they will then go to work killing the larvae. This method is preferable to using chemicals, as it is more effective at killing the larvae and is better for the environment.

Another reason why natural or organic methods are preferable is that they are often more affordable. Chemical methods can be quite expensive, and they often require special equipment or training to use. Natural or organic methods, on the other hand, are typically much more affordable and can often be done by homeowners themselves.

Overall, natural or organic methods are preferable for getting rid of leatherjackets for a number of reasons. They are more effective, better for the environment, and more affordable.

Beneficial Nematodes

Beneficial nematodes are a type of parasitic worm that feeds on insects. They are a safe and effective way to control pests like leatherjackets. You can buy them online or at some garden stores.

To use, mix the nematodes with water according to the package directions. Then, using a hose-end sprayer or watering can, apply the mixture to the affected areas of your lawn. The nematodes will enter the leatherjackets through their mouths and kill them from the inside out.

Beneficial nematodes are most effective when applied in late summer or early fall, when the leatherjackets are young and actively feeding. However, they can be used at any time of year.

Neem Oil

To use neem oil to get rid of leatherjackets, you will need to purchase a neem oil spray bottle and some neem oil. Fill the bottle with the neem oil, and then add water to the bottle until it is full. Shake the bottle well to mix the neem oil and water together. Then, simply spray the mixture onto the leatherjackets. The neem oil will kill the leatherjackets and prevent them from coming back.

Insecticidal Soap

Insecticidal soap is a type of soap that contains ingredients that can kill insects. The active ingredient in most insecticidal soaps is potassium salts of fatty acids, which are a type of fatty acid. When this ingredient is mixed with water, it forms a soap that can kill insects when it comes into contact with them. Insecticidal soaps are effective against a wide variety of insects, including aphids, whiteflies, and mites.

If you have found leatherjackets in your garden, don't despair! Although they can cause considerable damage to young plants, there are a number of ways to get rid of them. One effective method is to use insecticidal soap.

To make your own insecticidal soap, mix together equal parts water and unscented liquid dish soap. Add a tablespoon or two of this mixture to a spray bottle, and then spray it liberally on any plants that have been infested with leatherjackets. The soap will kill the larvae on contact, and if you keep up with regular applications, it will eventually eliminate the entire population.

Insecticidal soap is safe for use around humans and pets, but it can be harmful to beneficial insects like bees and ladybugs, so be sure to avoid spraying it on flowers or any other areas where these creatures might be present.

Horticultural Oil

Insecticidal soap is made from a variety of ingredients, including plant oils, animal fats, and soap. These substances are combined and diluted with water to create a solution that can be used to kill insects. The soap breaks down the insect's exoskeleton, causing it to dehydrate and die. Insecticidal soap is safe for use around humans and pets, and is an effective way to control pests in the home.

To use horticultural oil to get rid of leatherjackets, mix 1 part horticultural oil with 1 part water in a clean spray bottle. Make sure to shake the mixture well before each use. Spray the oil mixture on the leatherjackets, being sure to coat them completely. The horticultural oil will kill the leatherjackets on contact.
