Japanese Beetle | Waynes
  1. Japanese Beetle


Japanese Beetle

Description: The body is shiny, metallic green with copper-brown wing covers. There are approximately 5 small, white tufts under each wing with an additional tuft under the end of its abdomen.

Behavior: Social insect that congregates in large groups.

Diet: Feeds on plant material between the veins. Damage to leaves will appear to be “skeletonized”. Favors roses, maples, elms, grapes, crape myrtles, hops, canna, crab apples, poison ivy, and bracken.

Lifecycle: Japanese Beetles emerge between May and June and typically live about 30-50 days. When the soil starts to cool, they will retreat into the soil until the next year.

4 Life Stages of the Japanese Beetle:

  • Eggs - Small, white ovals that are laid in the soil.
  • Larvae - Small white grubs with V-shaped bristles under the tip of their abdomen.
  • Pupae - Grubs begin to take on a reddish-brown coloring.
  • Adult - Averages 3/8 inches in length

Control: Contacting a Pest Professional is strongly advised. At Waynes, we use one of two methods to control the Japanese Beetle. The first method controls the pest on contact. The second method is more systemic and will be taken up and translocated through the plant's vascular system. Should any beetles feed on the treated plants they will ingest the product and die.
