Green Lacewings - Common Questions and Answers

Green Lacewings

How long does it take the Lacewing eggs to hatch?
Lacewing eggs are laid and harvested daily to ensure the freshest, healthiest eggs are received. They can take 7-10 days to hatch at 65 degrees or higher and once they hatch they will be very difficult to see as they are very small approximately 3/8 of an inch and blend in with the foliage. It does take about another 2 weeks to start seeing a reduction in the pest.
    Green lacewings are general predators who feed on a variety of insects. They are natural enemies to: aphids, mealybugs, thrips, whiteflies, scale, and many more soft bodied insects. Green lacewings are an effective general predators in a wide range of growing temperatures and humidities. They can be used indoors and outdoors!
        During the larvae stage it is a predator. Larvae looks like alligators with noticeably long legs. Adults are strictly pollen feeders.
            For green lacewings, temperature of at least 60º F (15.5º C) is required for significant eating and egg-laying.
              Will the Lacewing eggs change appearance once they hatch?
              The Green Lacewing Eggs are very small, grey/green round eggs. Eggs are green when laid, and then darken before hatching.
                    When ordering green lacewing eggs in cards, you will not be able to see a drastic change in the appearance of the eggs in the card once they hatch.
                      Can I store lacewing eggs? If so, for how long?
                      Only the unhatched lacewing eggs can be stored. If cold storage is necessary, store at 40-46 degrees F., for no more than 10 days.
                        If the hatching process has already started, we recommend releasing the larvae as soon as possible. Newly hatched lacewing larvae are hungry and will cannibalize each other if they are not released quickly.
                          Are Green Lacewings the best option Spider Mite Control?
                          Even though green lacewings are general predator and will eat some spider mites, we recommend using predatory mites for better and faster control of spider mites.
                          I order the lacewing larvae but I don't see 1000 larvae in the bottle. Why?
                          They are about 3/8 of an inch and there will be only a few hatched before receipt if any as we do not want them to eat each other during transit. They are warm stored so they will hatch much quicker (usually in about 3 days) as opposed to the 7-10 days it takes for them to hatch if you were to just order the eggs.

                          Will ants harm my lacewings?
                          Ants will carry away the lacewing eggs and feed on them. Once the eggs hatch to larva the ants won't bother them. If ants are an issue where you are hanging the pouch/cards with lacewing eggs, remove it and keep it somewhere safe to allow them to hatch and as soon as you see hatching place it back on the plant. Ants won't harm the larvae. You can also make a perimeter of cinnamon or cayenne pepper around the base of the plant which deters ants.

                            I have ordered ladybugs 3 times this winter , and they did control the aphids. the last time one month ago, but I am not seeing any ladybugs anymore but now the aphids are coming back ?

                            I just ordered both green lacewing and predatory mites… just after purchase, I realized that the lacewing might eat the predatory mites. I have aphids and spider mites on my houseplants right now. Do you have any guidance for me, please?

                            I’m pretty sure this is the case. But just wanted to double check. If I get both lacewings and A. cucumeris, the lacewings will munch on the cucumeris right? I have found both scale and thrips on my plants so this is the reason I wanted to order both. Is there maybe another predatory insect that eats both of these pests?
