Japanese Beetles in Anaheim

Japanese beetles have been a widespread problem in the United States since their introduction in 1916, though they’re most common in states east of the Mississippi. These pests are known for destroying landscapes by consuming plant matter. Adults will feed on over 300 different plant species, while the grubs mainly destroy grass roots. Japanese beetles are also drawn to sunny areas and can cause significant damage to your garden within a short amount of time. 

Japanese Beetle Habitat

Since Japanese beetles can feed on such a wide range of plants, they can live almost anywhere as long as there’s vegetation. They’re found everywhere from forests and farms to urban gardens. Japanese beetles are often found on plants like roses, grapes, and raspberries. Thanks to their huge appetite and ability to fly from plant to plant, these beetles can make quick work of your landscape. Japanese beetles also generally feed on the soft tissue between leaf veins, which leaves a lace-like pattern once they’re done feeding. These pests are most active on warm, sunny days and often feed in groups.

Japanese beetles may have powerful jaws, but they’re not known to bite people or spread disease. That said, their destructive behavior is estimated to cost home and business owners a combined $460 million each year in repairs.

Infestations can quickly get out of hand, leading to widespread damage across all of your plants.
