Lace Bugs can be found feeding on your broadleaf evergreens trees throughout the summer.
Lace Bugs are common in our area and can be found on a variety of hosts, both evergreen and deciduous. During the summer, Lace Bugs are notorious for damaging broadleaf evergreens, such as rhododendron and azalea.
The Lace Bug
The rhododendron and azalea Lace Bugs are small, winged insects that only grow to be a few millimeters long. Their wings have a net-like pattern, and they are usually scattered with black or brown spots. Lace Bugs cause damage when feeding on a leaf due to their piercing mouths, which they use to suck nutrients out.
Identifying Lace Bug Damage
Lace Bugs will usually feed from the underside of a leaf, piercing and sucking the leaf and ultimately killing the cells, which in turn creates yellow spots on the top side of infested plants. When a plant becomes severely damaged, the leaves will take on a gray blotched appearance or turn entirely brown. If severe damage occurs, the plant may be beyond rescue.
Treating for Lace Bugs
Controlling Lace Bugs can be accomplished with a systemic insecticide; however, preventative measures are recommended if you have commonly infested plants, such as the rhododendron and azalea.
Investigate your broadleaf evergreens and look for yellow spots on the leaves. If you see yellow spots you likely have Lace Bugs feeding on the underside. Request a free consultation with a pest management professional to learn more about Lace Bug treatments and control.
