About Green Lacewings


Green Lacewings are available in three different stages — eggs, larvae, and adults. Lacewing eggs are the most economical choice for your customer although you will see faster results when you purchase live Lacewing larvae. Lacewing eggs are packaged in rice hulls for easy disbursement.During the 2-3 weeks before becoming an adult, the larvae will consume 200-300 Aphids each. All products come with complete release instructions and appropriate disbursement pouches.Lacewing larvae voraciously attack their prey by seizing them with large, sucking jaws and inject a paralyzing venom. The hollow jaws then draw out the body fluids of the pest. In general, they attack the eggs and the immature stages of most soft-bodied pests such as: aphids, thrips, spider mites, sweet potato & greenhouse whitefly, mealybugs, leafhoppers, and the eggs and caterpillars of most pest moths. Of all available commercial predators, this lacewing is the most voracious and has the greatest versatility for pests of field crops, orchards, and greenhouses.
Available in 3 different quantities, Lacewing eggs are the prime choice for shoppers due to their affordable pricing and large coverage area.

Each lacewing larva will devour 200 or more pests or pest eggs a week during their two to three week developmental period. After this stage, the larvae pupate by spinning a cocoon with silken thread. Approximately five days later adult lacewings emerge to mate and repeat the life cycle. Depending on climatic conditions, the adult will live about four to six weeks.
