Have a Japanese Beetle Problem?


The Japanese Beetle begins life in your lawn or in nearby grasslands where the white larvae eat the grass roots. The adult has a copper body with a green head and lives 1-2 years if food is available.

When mature the adult Japanese Beetle flies in search of other beetles that emit pheromones to attract each other for mating. The Japanese Beetle feeds on a wide variety of plants, eating the foliage and leaving the veins behind.


Copper and green




Adult Japanese beetles can be easily identified by their coloring. The Japanese beetle has a metallic green body with copper-brown wing covers. Adults appear from the ground and begin feeding on plants in the early summer. The peak of their activity lasts from late June through August or September when they will begin to die off due to temperature and climate. Japanese beetles live for up to two months during their adult life form.

Control Advice

Spray dish soap and water on plants and shake the plant in the early morning to knock off the dead beetles. They can also be picked off by hand. Dispose of beetles away from the plants you are protecting. Avoid using pheromone traps in your garden as they are known to attract more beetles. Beetles are not good fliers and miss the trap and land on your plants instead.

Active Seasons

The Japanese Beetle is active all year round, migrating with plant availability.
