Japanese Beetles on Crepe Myrtle: Rotate Insecticides, Manage Mites

Beetles Returned After Sevin? Rotate Chemistry

Repeated Sevin (carbaryl) can flare spider mites. Switch to acephate (Orthene) or malathion for beetles—they're softer on mites.

Beetles aggregate via pheromones—daily hand-picking into soapy water reduces numbers.
Spray early morning (sluggish beetles).
Rain washes off residue—reapply after heavy rain.
Fertilize & water to help tree tolerate stress.

Neem oil deters but fails under high pressure. Pyrethroids (permethrin) work but flare mites.
