Although Japanese beetles are known to feed on more than 300 types of plants, some are more appealing to them than others! Here’s a list of the best and worst plants to grow when dealing with Japanese beetles.
What do Japanese Beetles Like to Eat?
As larvae, Japanese beetles live underground, feeding on the roots of grasses and other garden plants. This often leads to brown spots of dead or dying grass in lawns—a tell-tale sign of a Japanese beetle larvae infestation.
The adults like to feed on a number of different fruit and shade trees, roses, shrubs, asparagus, corn, soybeans, and a variety of other vegetables and ornamentals. The beetles will also readily munch on geraniums, but geraniums contain a substance that temporarily paralyzes Japanese beetles, making them susceptible to predators. Geraniums are therefore often used as trap plants.
The U.S. Department of Agriculture (USDA) has identified the following best and worst landscape plants to have in your yard when hungry Japanese beetles come calling. Use these suggestions as guidelines if you’re adding new plants.

These plants are least favored by adult Japanese beetles and are less susceptible to destruction. (However, there is no guarantee that these plants won’t be attacked if there are limited food sources in the area!)
