Caterpillars Eating Azaleas

If you notice something nibbling your azaleas, caterpillars may be to blame. Caterpillars might damage shrubs, but rarely, if ever, kill them, according to the Alabama Cooperative Extension.

Indications

• Azalea caterpillars feed on azaleas during the spring and summer months. If you notice damage to the leaves during the winter months, pests other than caterpillars are the problem. Look for the caterpillar to hiding along the stem of the bush nearest the most recent leaf damage, advises the Azalea Society of America.

Identification

• Azalea caterpillars, known as Rhododendron Loopers, are red or brown with white or yellow stripes. Although the caterpillars are normally 1/4 to 1/2 inch long, they may grow up to 2 inches long at full maturity. Azalea caterpillars are mostly hazardous to azaleas; they do not bite or sting humans as other caterpillars might, according to the Alabama Cooperative Extension.

Steps

• Remove caterpillars from the plant and place them into a container of soapy water. Apply pesticide specifically made to treat against caterpillars directly to the plant. Pesticide will keep the plant from future re-infestation. The Azalea Society of America suggests consulting your local county extension service for the best pesticide for your area and type of azalea.
