The Q&A Archives: Beetles on Roses

Question: How do I get rid of the Japanese beetles that are eating my rose blooms? They seem to prefer my rugosa rose bush.

Answer: Beetles such as Japanese beetles on roses can usually be repelled by using a neem-based spray according to directions. Handpicking is also effective but a bit time-consuming; it works best in early morning or evening when the beetles are moving slowly. On the other hand, rugosa roses are very sturdy plants and I would not expect a beetle attack to kill the plant. You might decide that the damage is "acceptable" and not do anything about it except ignore it.
