16 Birds That Eat Japanese Beetles: Nature’s Pest Control

Japanese beetles are invasive garden pests that can cause significant damage to plants and crops. Fortunately, there are several bird species that prey on these beetles, offering a natural form of pest control.

In this blog post, we’ll explore some of the birds that eat Japanese beetles, complete with photos of each species. But first, let’s take a closer look at these pesky beetles and the damage they can cause.

What are Japanese Beetles?

Japanese beetles are small, metallic-green insects that are native to Japan. They were accidentally introduced to the United States in the early 1900s, and have since become a common garden pest throughout North America.

These beetles are known for their voracious appetite, feeding on the leaves, flowers, and fruits of a wide range of plants and crops. The damage caused by Japanese beetles can be severe, especially when populations are high.

They can defoliate entire trees and shrubs, leaving them vulnerable to disease and other pests. Additionally, the beetles release pheromones that attract even more beetles to the area, exacerbating the problem. To make matters worse, Japanese beetles are difficult to control.

Many traditional insecticides are ineffective, and they can harm beneficial insects and birds that help control other garden pests. However, by attracting and supporting bird populations in your garden, you can help naturally reduce Japanese beetle populations and protect your plants.

Where are Japanese Beetles Found?

Japanese beetles are most commonly found in the eastern and central regions of North America. They prefer warm, humid climates and can thrive in a variety of habitats, including gardens, lawns, and agricultural fields.

Japanese beetles are attracted to a wide range of plant species, but they have a particular preference for roses, grapevines, and fruit trees. They also feed on a variety of ornamental plants, including linden trees, hibiscus, and hydrangeas.

If you’re unsure whether Japanese beetles are present in your area, keep an eye out for their telltale damage. The beetles typically skeletonize leaves, meaning that they eat the tissue between the veins, leaving only a lacy framework.

They may also feed on flowers and fruit, causing them to wither and drop prematurely. Once you’ve identified Japanese beetle damage, there are several steps you can take to reduce their impact.

This may include removing damaged plant material, using physical barriers such as netting or row covers, or employing natural predators such as birds or beneficial insects.

By taking a proactive approach to Japanese beetle management, you can help protect your garden and support a healthy ecosystem.

How to Control Japanese Beetles?

Controlling Japanese beetles can be challenging, but there are several methods that can be effective. It’s important to note that there is no single “silver bullet” solution to managing Japanese beetles, and a combination of techniques may be necessary for effective control.

  • Handpicking: One of the most effective ways to control Japanese beetles is to handpick them from plants. This is a time-consuming but highly targeted approach, and it can be especially effective for small infestations. Simply knock the beetles off the plants and into a container of soapy water to drown them.
  • Natural predators: As we mentioned earlier, several bird species are known to eat Japanese beetles. By attracting and supporting these birds in your garden, you can help reduce beetle populations naturally. Additionally, beneficial insects such as nematodes, parasitic wasps, and tachinid flies can help control Japanese beetles.
  • Traps: Pheromone traps are available that can lure Japanese beetles into a container, where they are unable to escape. However, these traps can actually attract more beetles to the area, so they should be used sparingly and strategically.
  • Physical barriers: Using physical barriers such as netting or row covers can help prevent Japanese beetles from reaching vulnerable plants. This approach can be especially effective for fruit trees and other high-value crops.
  • Companion planting: Some plants are known to repel Japanese beetles or attract predators that feed on them. For example, planting garlic, chives, or other alliums near vulnerable plants can help deter beetles.
  • Insecticides: While insecticides should generally be used as a last resort, there are some products that can be effective against Japanese beetles. However, it’s important to use insecticides judiciously and follow all label instructions carefully to avoid harming beneficial insects and birds.

By combining these different methods, you can develop an effective and environmentally friendly strategy for controlling Japanese beetles in your garden. With a little bit of effort, you can help protect your plants and support a healthy ecosystem.

Frequently Asked Questions

What time of day are Japanese beetles most active?

Japanese beetles are often found around the garden, damaging plants and other garden produce. But when do they come out? Japanese beetles can be active during the day or night, but it is most common to see them in the morning hours between 7am-10am. 

Why are Japanese beetles bad?

Japanese beetles are an invasive species of beetle that have taken over the eastern half of North America. They feed on over 300 types of plants and can cause significant damage to gardens. They pose a serious threat to natural ecosystems because they consume so many leaves, which in turn deprives native insects and animals from food sources. 

What can I spray on plants to keep Japanese beetles away?

There are two ways to protect your plants from these pests: The first is using an organic pesticide such as rotenone, pyrethrum, or neem oil. These pesticides should be applied every few days and reapplied after heavy rain or watering. The second way is to use a chemical pesticide such as carbaryl (Sevin), cyfluthrin, malathion, and permethrin.

What do Japanese beetles hate?

There are many types of plants that repel Japanese beetles; some include rosemary, garlic, onion (and chives), lemongrass, catnip, lavender (and thyme), peppermint (and spearmint). I also found that Pyrethrum daisies, marigolds, and tansy work well.

Will birds eat dead Japanese beetles?

Birds will not eat dead beetles, but they will attack live ones if given the opportunity. Birds typically feed on live insects and spiders that they catch while flying around trees and other plants. 


In conclusion, Japanese beetles can be a serious garden pest, causing significant damage to plants and crops. However, by understanding their biology and behavior, and by implementing a combination of control methods, it’s possible to manage their impact effectively.

By attracting and supporting natural predators like birds, using physical barriers, companion planting, or handpicking, gardeners can reduce Japanese beetle populations naturally and avoid the use of harmful chemicals.

It’s important to take a proactive approach to Japanese beetle management to protect your garden and promote a healthy ecosystem. By doing so, you’ll be able to enjoy a thriving garden and support the birds and other beneficial insects that help keep it that way.
