Holes in Azalea Leaves

Q: What is chewing holes in my azalea leaves? This happens every year around July on otherwise healthy bushes.

A: It’s cranberry rootworm. The larvae feed on roots and adults feed on leaves from the underside, at night, making characteristic curved holes. Control with imidacloprid (Bayer Tree and Shrub) soil drench or spinosad (Captain Jack’s Dead Bug Brew) sprayed under leaves at night.
