Green Lacewing Eggs on Hanging Cards allow for easy and even release of lacewing eggs throughout the growing area. Ideal for use in orchards, indoor growing, greenhouses and row cropping. Introduce green lacewing at the first sign of pest infestation for best results. Please call us at 1-800-827-2847 to set up a recurring shipment program.
Green Lacewing Preferred Food: aphids, mealybugs, spider mites, leafhopper nymphs, moth eggs, scale, thrips, and whiteflies.
Optimal Temperatures: 67-90°F, RH >30%
Life Cycle & Behavior: Lacewing eggs hatch within 3-10 days of receipt depending on temperature and humidity in the release area. Once hatched, lacewing larvae feed for 2-3 weeks on a variety of soft-bodied insects. Larvae are recognizable by their prominent mandibles (mouthparts), alligator-like appearance and pale coloration with dark markings. The larvae molt as they grow and mature through 3 instar stages. Pupation occurs in silken cocoons on the undersides of leaves or under loose bark. Green lacewing will overwinter in the pupal stage in cooler climates. Adults emerge from the cocoons with large veined ("lacy") wings ready to mate and lay more eggs. Adult green lacewings feed on pollen, nectar and honeydew while aiding in pollination. The complete life cycle lasts roughly 30 days.
- In gardens and greenhouses, release eggs at approximately 1,000 eggs per 2,000 sq. ft.
- For farms release 5,000 to 50,000 per acre depending upon infestation.

Hang Green Lacewing Cards within the canopy of individual plants where possible. If it is not possible, find shaded or protected areas and hang cards from suitable branches. Green lacewing larvae will hatch out from the eggs on the cards and move onto plant foliage in search of pest insects (food). Once hatched, green lacewing are tolerant of high temperatures and remain effective in high and low humidities. For these reasons, they are an excellent general predator in virtually any growing environment.
What Should I Expect After Release?
Green lacewing eggs will hatch within 3-10 days of receipt. Lacewing larvae are difficult to spot once hatched out and camouflage well with their surroundings. Additionally, the larvae and adults are mainly active at night when temperatures and predators are lower in number. Try using a black light to spot larvae moving on the plant during dusk or evening hours. Larvae become more evident and noticeable one to two weeks after hatching once they have grown and molted. Pay close attention to areas of high pest pressure, undersides of leaves and places where branches and leaves meet. The larvae continue to grow as they feed and molt prior to pupation.
Green lacewing are most effective when introduced early in the growing season as a preventative measure. It is imperative to make multiple releases of green lacewing, particularly if they are being used to control an active pest infestation. The time it takes for control to be achieved is dependent on the severity of the infestation being treated. Typically, changes in pest populations become evident within 2-3 weeks of hatching. Keep in mind that beneficial insects work at a slower pace than chemical controls. If immediate knockdown or control of an insect population is necessary, consider spraying a fast-acting insecticide or select a more targeted predator/parasite.
Adults lay eggs near larval food sources, so adult activity will be higher in those areas. They will appear around one month after release of the eggs and tend to disperse if food sources are limited. Providing plants that bloom and pollinate at different times of the year helps to cultivate a habitat that is suitable and attractive to the adult green lacewing.
