A Bt for beetles

The label says beetleGONE! is highly active against certain beetles in the Buprestidae, Scarabaeidae and Curculionidae families. Its pest tables list Japanese, Oriental and green June beetles, two borers and several weevils.[1]

The master label also covers food crops with a 0-day pre-harvest interval and darkling and hide beetles in poultry houses.[1]

Where it is used

Spray the leaves the beetles are eating until they are thoroughly wet but not dripping. The beetles have to eat treated foliage for it to work.[1]

Time sprays for after adult beetles emerge but before their peak flight, and repeat as needed until they are gone.[1]

Multiple treatments may be needed when beetles keep flying in from neighboring yards. Mix only enough for one treatment.[1]

Measure with dedicated spoons, never food utensils. Trigger, hand-held, backpack and hose-end sprayers all work.[1]

Safety and environmental hazards

People

Signal word CAUTION: causes moderate eye irritation and is harmful if absorbed through the skin or swallowed. Avoid contact with skin, eyes and clothing, and wash with soap and water after handling.[1]

Pets

For lawns, grounds and ornamental gardens, the commercial sublabel says to keep unprotected people, children and pets out of the treated area until sprays have dried.[1]
