What Are Japanese Beetles?
Japanese beetles (Popillia japonica) are among the most adverse pests in North America, infamous for their capacity to devastate lawns and gardens. Originally from Japan, they were first discovered inside the U.S. In 1916, a rapidly unfolding event caused tens of millions of dollars in damage to both homeowners and industries. According to the United States Department of Agriculture, these invasive insects are responsible for an estimated $460 million in lawn harm every year.
But it doesn’t stop at lawns – Japanese beetles also are a prime threat to pastures, plants, or even golf courses. A hazard assessment with the aid of the British Columbia Ministry of Agriculture expected that if these beetles were to spread in the area, they could cause $14.5 million in annual crop losses, at the same time as the golf enterprise alone could see $13.6 million in turf grass damage. Their effect is sizable, making effective prevention and treatment important for homeowners seeking to protect their outdoor area.
Identifying Japanese Beetles
- Adults: Metallic green heads, copper-colored wings, and oval-shaped bodies about half an inch long.
- Grubs: White, C-shaped larvae with brown heads that feed on grassroots.
Signs of Japanese Beetle Damage
Before you can efficiently control Japanese beetles, you need to identify the signs and symptoms. Here are important indicators of Japanese beetle damage:
1. Skeletonized Leaves
Adult Japanese beetles feed on the tissue between leaf veins, leaving behind a lace-like pattern. This is one of the most obvious signs and symptoms in their presence.
2. Brown Patches in Your Lawn
Grubs feed on the grassroots, inflicting the turf to brown and die. If you notice irregular brown patches in your lawn, it can be a sign of Japanese beetle lawn damage.
3. Spongy or Loose Turf
As grubs wreck grassroots, the connection between the grass and soil weakens, making your lawn sense spongy or free underfoot.
4. Increased Animal Activity
Birds, raccoons, and skunks are natural predators of grubs. If you observe animals digging up your garden, it can imply a grub infestation.
5. Turf Detachment
In severe cases, extensive root damage from grubs can cause the grass to detach from the soil, coming off like a rolled carpet.
How to Control Japanese Beetles
Controlling Japanese beetles requires a multi-pronged approach. Here are the only methods that provide a way to kill Japanese beetles and prevent similar damage.
1. Hand-Picking Adult Beetles
For small infestations, hand-picking can be an effective way to control adult beetles.

5. Use Nematodes for Grub Control
Nematodes are microscopic insects that infect and kill grubs. Apply these treatments on your lawn in late summer or early fall when grubs are most active.
6. Milky Spore Treatment
Milky spore is a bacterium aimed at Japanese beetles. Although it takes time to establish, it can provide long-term control.
