Azalea Caterpillar Control
Azalea caterpillar control
Spray the shrubs with any insecticide labeled to control caterpillars on ornamentals. Organic options include spinosad (various brands) or a Bt insecticide (Dipel, Thuricide and other brands). Permethrin or bifenthrin (various brands at your local nurseries and feed and seed stores) will provide the fastest knock down.
