How to get rid of adult beetles?

1. Difference Between Adult Cockchafers and Larvae

It is important to understand that adult beetles and larvae (white grubs in the lawn) do not cause the same damage around the house and in the garden.

• Adult cockchafer: adult beetles and flying beetles love to nibble the leaves of rosebushes, oaks and birches. They also feed on fruit so watch out for your fruit trees.
• Cockchafer larvae: White grubs feed on the roots of plants and flowers and love the roots of grass and cereals.

It is the beetle larvae that destroy the lawn and not the flying beetles!

2. What attracts beetles?

Before moving on to products and repellents to keep beetles away, why not find out what attracts beetles in the garden and at home!

Here are 3 possible causes of beetles around the house and in the garden:

• A lawn that is too short makes it easier for adult beetles to lay their eggs.
• The cultivation of potatoes and also strawberries in the garden are appreciated by these flying insects.
• Artificial light around the house at night attracts them even more.

So if you have an invasion of beetles at night, turn off the outside lights quickly to get rid of them!

3. Diatomaceous earth against beetles

If you are looking for a way to get rid of beetles and grubs naturally then diatomaceous earth is a natural product to buy.

4. Tilt your garden soil in search of beetles

If you suspect the presence of black cockchafer or fuller beetle larvae in the garden and in the lawn, the soil must be turned over. It’s a drastic solution, but really effective to get rid of beetle larvae and white grubs that ravage the lawn.

It is very difficult to kill all the beetle larvae, hence the importance of turning the garden soil a few times in early spring before the soil becomes too dry. Once the earth is turned over, open your eyes and collect all the beetle larvae you find and get rid of them quickly.

The larvae feed on the roots of grasses and plants!

It is not beetles that cause serious lawn and garden problems, but grubs and grubs. Indeed, these parasites feed on the roots of grasses and plants, causing the death of these plants and therefore the death of your beautiful lawn.

5. Kill beetle larvae with nematodes

Nematodes are microscopic worms that can paralyze beetle larvae and other white grubs in soil and grass. After a heavy rain or simply after having watered your lawn well, disperse the nematodes on the lawn. The microscopic worms will join the beetle larvae in order to eliminate them for good.

Beetle larvae can quickly damage your beautiful green lawn by attacking the roots of the grass. It is therefore important to kill grubs and grubs quickly to avoid damaging the entire lawn.

As it is a specialized product, it is not found everywhere. So, ask your garden center or some hardware stores to check if they have nematodes against white grubs and beetle larvae.

6. What animal eats beetles?

In addition to moles, other animals and birds can help you get rid of beetles and grubs in the lawn and garden.

• Hens: If you live in the countryside, why not buy a chicken? In addition to having good fresh eggs every day, you will no longer have any cockchafer larvae and other unwanted worms on your land.
• Raccoons and skunks: If you notice the presence of small holes on the surface of the lawn, it is undoubtedly the raccoons and skunks who are feasting on the beetles and white grubs. This is a good signal of the presence of larvae and worms in the lawn.
