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.

                          My wife and I have an IKEA cabinet that we converted into a mini greenhouse and we have approximately 20 plants in it. What happens if/when we are finished with the lacewings and don’t want any more on our plants and in our greenhouse? Do the lacewings eventually die off or do eggs continuously hatch over and over forever?

                          What do I do if there are too many lacewing adults during the adult stage in my IKEA Milsbo cabinet with about 25 plants? 1,000 eggs seems like way too many for only 25 plants but I can’t find less than 1,000 being sold anywhere! Do way less than 1,000 eggs hatch by any chance (I hope)?

                          I have lacewing eggs on my plants! The only thing is I don’t have a aphid problem. There was mealy bugs on one small plant 2 weeks ago but this was before I saw the eggs & I killed the mealybugs. Will my lacewings starve? What will they eat?

                          Will lace wing eggs survive if submerged in water? If so, for how long will they last?

                          I received lacewings that I ordered and put them in the little boxes they sent. Should I be giving them water? What do I do now?

                          I ordered the small garden pk a few weeks ago. I released the ladybugs but since the day after release have not seen any at all! I also hung the green lacewig rice pouches away from direct sunlight & never see any ants in or around my raised gardens. I never saw anything emerge & I’ve been keeping an eye on them to see if I could see anything but with how small they are I have not! The only thing I’ve noticed that changed is it looks like the rice has split open & not sure if that’s a good thing? Also still waiting for my praying mantises to hatch! I have aphids, thrips, spider mites, fungus gnats, white flys, & cucumber Beetles & every other spring/summer bug eating & destroying everything in my garden & even my house plants. I’m literally at my wits end on what I can do! I really do not want to use chemicals or spray any chemicals that could be harmful to the ladybugs & green lacewigs. That I have already released if there is even anything left since Idek if the lacewigs even hatched since it’s to hard to tell! Please help I’m feeling very defeated with the bugs eating everything especially since I do have veggies & fruits that are finally starting to emerge & the last thing I want is to not be able to pick/eat what I have grown & worked so hard on!!

                          Hello! I have lacewings for the first time. Lost the directions…😖 So. Do we spread them along the ground OR put them in the pouches.
                          Thank you!

                          Can the green lacewing handle temperatures in the 90 to 110F range?

                          Aimee said:

                          Do nighttime temperatures need to be above 60° to disperse the eggs outdoors? How many cards come with 1000 eggs? Do you disperse the eggs in rice hulls onto the soil? If so do they need to stay dry? Do the eggs on cards need to stay dry?

                          Just received my lace wing larvae and I’m a bit disappointed in the amount that were alive /in the bottle. Unsure if i just got a fluke bottle but there were probably only 20 that didnt look dead.

                          We received our order of lacewing eggs 3 days ago. We ordered them through Amazon. We kept the bag inside and watched for any movement. There were only a small amount of dark specks we could see on the edges of the bag. We looked with our magnifying glass and could see the dark eggs. There were a few green specks but no movement. We put them out in the bags in our rose bushes today but it looks like they are not hatching and there were no where’s near 1,000 eggs.

                          I ordered lacewing eggs and received them yesterday. I see no movement yet, just the rice hulls and tiny black specks. Should I wait to see movement or go ahead and put the eggs out?

                          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?

                          Daan said:

                          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?
