While the beautiful adult lacewings do not feed on insects, their larval stage has a ravenous appetite and can consume huge numbers of insects a day. They effectively control aphids, mites, whiteflies, mealybugs, leafhoppers, thrips, and caterpillars. Lacewings are sold as ready-to-hatch eggs in containers with rice hulls and a food source. To release lacewings scatter the contents of the container on and around infected plants. As soon as the eggs hatch the tiny lacewing larvae will immediately begin searching for and consuming insects. They will later pupate into adults which will lay eggs (one or more filaments with a tiny white egg at the end), and the process will begin again. Lacewings can be released throughout the growing season. NOTE: Avoid the use of electric bug 'zappers' as these kill far more lacewings than damaging pests.
