How to Get Rid of European Chafers (Natural & Organic Methods)

By Sabrina Wilson / July 27, 2022

The European chafer (Rhizotrogus majalis) is a destructive species of beetle that is native to Europe. It was first discovered in North America in the province of Quebec in the late 1960s, and has since spread to at least thirteen states and three Canadian provinces. The European chafer is a serious pest of turfgrass, and is responsible for major economic losses in the turfgrass industry. The larvae of the European chafer feed on the roots of grasses, and can cause extensive damage to lawns, golf courses, and other turfgrass areas. The European chafer is difficult to control because it has a wide range of host plants and can rapidly adapt to new environments.

There are a few reasons why natural or organic methods are preferable for getting rid of european chafers. First, these methods are much safer for the environment. Second, they are often more effective than chemical methods, since the chafers are less likely to develop resistance to natural predators or diseases. Third, natural methods are less likely to harm beneficial insects or other organisms that might be present in the soil. Finally, using natural methods just makes good sense - why use potentially harmful chemicals when there are safer and more effective alternatives available?

Beneficial Nematodes

Beneficial nematodes are common enemies of European chafers. The larvae of these beneficial insects parasitize and kill chafer grubs in the soil. They are most effective when applied in early summer, when chafer grubs are small. The best time to water them in is early morning or evening, so they don’t bake in the sun. Apply them to damp soil, and water them in well. Keep the soil moist for a week or so after application.

Neem Oil

If you're interested in using neem oil to get rid of European chafers, there are a few things you should keep in mind. First of all, neem oil is a powerful insecticide, so it's important to use it with care. Second, neem oil is most effective when used early in the season, before the chafers have a chance to lay their eggs. Finally, be sure to apply the neem oil to the soil, not the plants themselves, as it can be harmful to plants.

To use neem oil to get rid of European chafers, mix 1 tablespoon of neem oil with 1 cup of water. Add a few drops of dish soap to help the mixture spread more easily. Then, use a garden sprayer to apply the mixture to the affected areas. Be sure to spray the soil around the plants, as well as the underside of the leaves, where the chafers are likely to lay their eggs. Reapply the mixture every week or so for best results.

Insecticidal Soap

Insecticidal soap is made from potassium salts of fatty acids. Fatty acids are molecules that have a long hydrocarbon chain and a carboxylic acid group. This soap is used as an insecticide because it can kill soft-bodied insects on contact. The soap works by breaking down the insect's protective wax layer, causing the insect to dehydrate and die. Insecticidal soap is safe to use around most plants, and will not harm beneficial insects such as ladybugs and bees.

To use insecticidal soap to get rid of European chafers, add two tablespoons of dish soap to a gallon of water and mix well. Next, use a garden hose to spray the mixture onto the leaves of your plants, making sure to coat the undersides of the leaves where the insects are likely to be hiding. Be sure to spray in the early morning or evening when the temperatures are cooler to avoid harming the leaves of your plants. Repeat this process every few days until the insects are gone.

Horticultural Oil

Insecticidal soap is a soap that is made with insecticidal ingredients. These ingredients can include things like soapwort, neem oil, and pyrethrin. Insecticidal soap is used to kill insects and larvae. It is safe for humans and animals to use, but it is deadly to insects.

Horticultural oil can be effective in controlling European chafers. The adult beetles are most active from late May to early July and are attracted to light-colored objects, making them easy to spot. At this time, they feed on the leaves of turfgrass, especially ryegrass and Kentucky bluegrass. The grubs, or larval stage, feed on the roots of turfgrass from late August through early May. To control adults, spray horticultural oil on foliage in late May or early June, when they are first seen. For best results, apply the oil when temperatures are above 60 degrees Fahrenheit and bees are not active. To control grubs, treat turfgrass with horticultural oil in late August or early September.
