Perfectly Round Holes in Rose Buds? Night-Feeding Beetles Are the Culprits

A gardener noticed 1/4-inch diameter, 1/8-inch deep circular holes in rose buds, some with multiple spots.

Beetle Damage

Caterpillars eat leaves; beetles eat buds. The clean, circular holes are classic beetle feeding. Beetles are nocturnal—inspect plants at night with a flashlight to find them. They lay eggs at the base of the plant.

Control

Use a rose insecticide labeled for beetles. Spray the base thoroughly to target eggs and larvae. Beetle infestations are often short-lived (a few weeks).
