How to Get Rid of Japanese Beetles: The Ultimate Guide

Japanese beetles are a common garden pest that can wreak havoc on your plants. These shiny green and copper-toned beetles typically emerge during the summer months and can be incredibly destructive. Not only do they eat away at leaves and flowers, but they also attract other pests, such as birds and rodents, who feast on them. If left unchecked, Japanese beetles can quickly become a real problem. Fortunately, there are a number of ways to get rid of these pests, both naturally and chemically. In this article, we will explore the various methods for getting rid of Japanese beetles, including the benefits and drawbacks of each approach.

Natural Ways to Get Rid of Japanese Beetles

If you are looking to get rid of Japanese beetles naturally, there are several options available. One popular approach is to introduce predators such as birds, praying mantises, or nematodes that will feed on the beetles and their larvae. Another natural approach is to use pheromone traps, which attract the beetles to a particular location where they are trapped and then disposed of.

Companion planting is another effective natural method for controlling Japanese beetles. Certain plants such as garlic, chives, and marigolds act as natural repellents, keeping the beetles away from your garden. Additionally, plants like catnip and Tansy can actually repel the beetles and reduce the damage they cause.

While natural methods can be effective, they do have their limitations. For example, introducing predators or using pheromone traps may not be enough to control a severe infestation. Nevertheless, combining these natural methods with other strategies can maximize their effectiveness.

Chemical Solutions for Getting Rid of Japanese Beetles

For those who prefer a more aggressive approach, chemical insecticides can be used to kill off Japanese beetles. These insecticides can be sprayed directly onto the plants, killing beetles on contact. They can also be used as a preventative measure to protect plants before they are infested.

While using chemical insecticides can be an effective way to deal with Japanese beetles, there are some drawbacks to consider. For example, these chemicals can be harmful to beneficial insects such as bees and butterflies and may be toxic to other animals that come into contact with them. Additionally, repeated use of insecticides can lead to the development of resistant insects, making it more difficult to deal with infestations in the future.

If you do decide to use chemical insecticides, it is important to read and follow the instructions carefully and use them safely and sparingly.

DIY Japanese Beetle Traps

Another option for controlling Japanese beetles is to make your own traps. These traps can be made with either a pheromone or a baited lure and can be purchased at most garden stores or made at home.

The simplest type of DIY Japanese beetle trap is a disposable plastic bag with a baited lure. The beetles are attracted to the bait and become trapped inside the bag. Another popular type of trap is a bucket trap. In this case, a bucket is filled with soapy water and placed underneath a bucket with a hole. Japanese beetles are attracted to the plant on top and fall into the water and drown.

It is important to use traps effectively for maximum effectiveness. Traps should be placed away from your garden to avoid attracting more beetles to your plants. Additionally, traps need to be emptied regularly to avoid drawing other pests to your garden.

How to Prevent Japanese Beetles from Infesting Your Garden

The old adage of “prevention is better than cure” applies to Japanese beetles as well. There are several steps you can take to prevent Japanese beetles from infesting your garden in the first place, such as planting certain types of vegetation, using mulch, and setting up barriers to keep the beetles away.

Planting certain types of vegetation, such as garlic, chives, and marigolds, can act as natural repellents, keeping Japanese beetles away from your garden. Mulching your garden can also help prevent beetles from laying their eggs in the soil. Covering plants with netting or cloth barriers can also be effective in keeping beetles away, especially during peak season.

It is also important to practice good garden hygiene, removing dead leaves and plant debris and keeping your garden free of clutter. This can reduce the potential for pests to hide and breed in your garden.

Best Practices for Removing Japanese Beetles

If you spot a Japanese beetle in your garden, it is important to act quickly to avoid an infestation. One of the most effective ways to physically remove Japanese beetles from your garden is to use a soap mixture to drown them in. Alternatively, you can pick the beetles off one by one and dispose of them.

While these methods can be effective in removing Japanese beetles, they do have their limitations. For example, picking off beetles one by one can be a labor-intensive process, and it may be difficult to collect them all. Furthermore, removing beetles by hand may not be possible if the infestation is severe.

How to Get Rid of Japanese Beetles Without Harming Beneficial Insects

When trying to get rid of Japanese beetles, it is important to avoid harming beneficial insects like bees, butterflies, or ladybugs. There are several ways to do this, such as using insecticides that target only Japanese beetles, using traps that capture only Japanese beetles, or physically removing beetles with soap mixture or by hand.

Another option is to use natural repellents like garlic, chives, and marigolds, which are harmless to beneficial insects. Similarly, pheromone traps can be used in a way that minimizes their impact on beneficial insects.

How to Deal with a Severe Japanese Beetle Infestation

If you are dealing with a severe infestation of Japanese beetles, it may be necessary to take more drastic measures. In this case, you may need to consider using chemical insecticides or calling in a professional exterminator.

Alternatively, you may need to remove the soil from your garden to get rid of eggs and larvae that have been laid in the soil.


In conclusion, there are several methods for getting rid of Japanese beetles, both naturally and chemically. Using a combination of these methods can be the most effective approach at controlling Japanese beetle infestations. Furthermore, prevention is key, and it is important to implement strategies to prevent Japanese beetles from infesting your garden in the first place. Ultimately, the goal is to balance effective pest control with preserving the ecosystem of your garden.
