Elimination, Biology, Description of Lace Bugs
Description and Damage
Lacebugs are small (1/8 inch) insects of the family Tingidae, which means
"ornamented." The adults have delicate clear wings that they hold flat
over their bodies. The wings have many, giving them a lacy appearance.
Immature lacebugs are dark and wingless, with spines radiating from the edges of
Lacebugs are pests primarily of ornamental trees and shrubs, although several species
infest a few vegetables. Most lacebugs feed on only one type of plant. They
damage plants by sucking the sap and cell contents from the undersides of the leaves,
producing a mottling or speckling on the upper surfaces. Lacebug damage often
resembles leafhopper or spider mite damage. However, lacebugs excrete drops of
shiny, varnish-like excrement, which accumulates around them as they feed. Several
generations of lacebugs occur each year. Certain lacebugs may build up to such
tremendous numbers on their host plant that very little green tissue remains to produce
food for the plant.
Lacebugs should be controlled early, before they cause much damage.
This is especially important on broad-leaved evergreen plants because they retain
the unproductive leaves for several years.
To kill lacebugs on evergreens and other non-food plants and ornamentals, use Acephate Pro 75. This is a water-soluble
powder concentrate that can be applied using a hose-end sprayer (Dial-A-Mix) or pump type (Chapin) garden sprayer. Acephate Pro 75 is a systemic insecticide; do
not irrigate treated area for at least 48 hours after application of the insecticide.
For best results, spray for lacebugs in late evening or early morning. Repeat
application in about 10 days, if necessary. Keep people and pets off all treated
areas until dry.
To kill lacebugs on edible food crops, use Bonide
Fruit Tree Spray. This product contains several active ingredients and
will control insects, fungus, mites, scale on most fruits, ornamentals, evergreens and
