Green Lacewing Adults - FAQs

Do green lacewing adults eat aphids?
No. Adults feed on nectar, pollen, and honeydew. The pest control comes from their offspring. Adults lay eggs near pest colonies, and the larvae that hatch are the ones that hunt aphids and other soft-bodied pests.

How long before I see results from adults?
Expect a lag. Adults need time to find pests and lay eggs, and the eggs take several days to two weeks to hatch, depending on temperature. For faster results, pair adults with a larvae release.

Will the adults fly away?
Adults are strong fliers and will spread out, making them useful for large areas. Releasing near pest activity and providing a food source like flowers or supplemental food encourages them to stay and lay eggs where you need them.

Can I use lacewing adults indoors or in a greenhouse?
Yes. Adults work well in greenhouses and larger indoor growing spaces, where they stay close to your plants. In a very small space, such as a few houseplants, eggs or larvae are usually the better fit.

What should I do about ants?
Ants protect aphid colonies and will eat lacewing eggs. Control ant activity before or alongside your release so the eggs the adults lay have a chance to hatch.

Can I use insecticides alongside lacewings?
Broad-spectrum and systemic insecticides are toxic to lacewings. Wetting agents and spreader-stickers can also harm them. Avoid these products before and during your lacewing program.
