Green Lacewing Eggs Hanging Cards - FAQs

What is a lacewing?
A lacewing is a common beneficial insect used in biological pest control. Only the larval stage actively hunts pests. Adults feed on pollen and nectar and lay eggs near aphid colonies.

Do lacewing larvae bite?
Lacewing larvae have small pincer-like mouthparts they use to grab prey, and they can pinch if handled directly, but they don't bite or sting people in any harmful way.

How long does the lacewing life cycle take?
Eggs typically hatch in a few days to two weeks, depending on temperature. Larvae then hunt for 2–3 weeks before pupating, and adults live another 4–6 weeks. A single generation can take roughly 6–8 weeks from egg to adult, depending on temperature.

Should I buy lacewing eggs, larvae, or adults?
Eggs are the more economical option for larger areas and work well for prevention or light pest pressure. Larvae are hatched upon or shortly after delivery. Adults don't eat pests. Instead, they lay eggs near pest populations, and those eggs hatch into larvae that feed.

Why didn't my lacewing adults control my pest problem?
Adults feed on flower pollen and nectar, not on pests. Green lacewing adults establish a new population by laying eggs near pest activity, so control comes once those eggs hatch into larvae. For immediate control, choose larvae instead.
