Keeping Japanese Beetles Off My Roses

Question

Beetles appear on blooms in June and eat them until they are ruined

Answer 1

The best way is to use nature! There is a nifty little bactereum called Milky Spore (Paenibacillus papillae) that will, absolutely, devastate the offending overpopulation. Using this in combination with chemical controls and proper companion planting, you can eliminate these pests from the area, successfully.
