Green Lacewing - Eggs, Larvae, Adults

Pest Control With Green Lacewing in Gardens and Greenhouses

Green Lacewing for garden pest control


Green Lacewing are an exceptional addition to any IPM (Integrated Pest Management) program. ARBICO’s green lacewing are common inhabitants in much of North America. Adults feed only on nectar, pollen, and aphid honeydew, but the larvae are active predators. Be sure to provide food for the adults so they will stay and deposit their eggs.

Green Lacewing larvae are voracious predators of the eggs and immature stages of many soft bodied insect pests, including several species of aphids, spider mites (especially red mites), thrips, whitefly, leafhoppers, some beetle larvae, eggs of pest moths, and mealybugs. The larvae will feed for 2-3 weeks, spin a cocoon, and emerge as adults 10-14 days later. These little beauties are a wonderful and cost effective addition to any pest control program and work in concert with most beneficial insects.

Which type you order depends on how severe your infestation is:

Green Lacewing Eggs: If you just want to establish Green Lacewing at the beginning of the season or have a limited infestation, choose the appropriate numbers of eggs for your garden or greenhouse. The larvae usually take 3-10 days to emerge following receipt of your order, depending on the temperature and other environmental conditions. Repeat the application in two weeks. Green Lacewing eggs are also shipped in hanging release packs and on cards.

Weekly Ship Programs: If you have a moderate to severe infestation, consider going on a program. This will deliver the appropriate number of eggs to you weekly or bi-weekly for at least 3 shipments. It is recommended that you release Green Lacewing eggs every 7-10 days to ensure a continual supply of larvae feeding on pests and varying life stages throughout the control area.

Larval Frames and Bottles: If you have a more severe infestation, consider the larval frames or bottles. The larval stage of the green lacewing provides the quickest means to control unwanted pests, since they arrive ready to eat your pests. The larvae packaged in frames have small compartments that can be peeled open a little at a time to make releases in various areas. Larvae can also be provided in a bottle, though it is more difficult to make a completely even application. Larvae should be released immediately.

Lacewing Adults: If you are treating a large area and do not have the time or means to release eggs or larvae, order adult lacewing. The adults come ready to lay eggs and will do so immediately throughout your release zone, but do not actively control pests themselves.

Beneficial insects are most effective when released preventatively or at the first sign of pests. Apply periodically over the course of a growing season. ARBICO Organics is happy to work with you to develop an IPM program; however, results will vary based upon growing environment, growing conditions (temperature, relative humidity), interactions with native insect populations, growing medium, etc. Please provide as much detail about each of these factors as possible when dealing with one of our pest control specialists. This allows us to make the most accurate and cost-effective recommendations possible.
