Japanese Beetle – How to control or kill

The Spider Mite



Description: Metallic green/copper adult grows to 1/2″ long.

Larvae or grubs are grayish-white with brown head; fat

body is 3/4″ long. Adults especially like beans and

corn but will eat almost any plant, often skeletonizing

the leaves. Larvae chew on roots of lawn grass, bean,

beet, sweet corn, onion and tomato; except during cultivation,

they are seldom noticed, but their root pruning action

severely reduces crop yields and can kill grass. Growth

of grubs and root damage is mostly in June. Adults cause

damage from late June to early September.

Solution: To protect

lawn grass roots from chewing damage, apply Grub-Away Nematodes at the rate of

10 million per 600 sq. ft. of lawn. For adult beetles

use Neem-AwayTM Insect

Spray to repel beetles; PyolaTM Insecticidal

Spray or Liquid Rotenone/Pyrethrin to kill

them; or Japanese Beetle Traps with pheromone

lures to mass-trap them. Set out traps in mid-June,

before beetles emerge, preferably in sun, 50 feet or

more downwind of vulnerable plants.
