Chemical Control for Japanese Beetles: When Hand-Picking Isn't Enough

Too many beetles to pick? Insecticides work, but choose wisely:

  • Carbaryl (Sevin, Bug-B-Gon)—very effective, lasts only a few days.
  • Permethrin/Resmethrin—fast knockdown, good for immediate satisfaction.

Traps: Use With Caution

Traps lure beetles from neighbors' yards to yours. If used, place at far corners of property so beetles fly away from prized plants.

Spray early morning or late evening to spare bees. Rotate chemicals to delay resistance.
