Japanese beetles are green or metallic blue in color with coppery wings and bodies that measure around a half-inch in length. Because they are a destructive species that consumes flowers and leaves and target hibiscus and rose bushes, many gardeners look for ways to eradicate them from their gardens.

For light infestations of Japanese beetles, picking the bugs off affected areas by hand is a good option. Gardeners can use gloved hands to remove the beetles physically from the plant, depositing them into a bucket of soapy water as they work, and then disposing of the soapy water once finished.

Pesticides to kill off Japanese beetles are also effective. Pesticides containing permethrin, acephate and carbaryl are usually effective. Neem-based organic options also provide control of beetles. Additionally, some insecticidal soaps are recommended.

Live nematodes, which are known as Heterorhabditis bacteriophora, can be applied to the lawn in the early spring. These nematodes infect the grubs, which are beetles in their larval stage, killing them before they have a chance to morph into actual beetles.
