Green Lacewing Larvae

At A Glance

Chrysoperla carnea Larvae are the aggressive, high-impact "infantry" of biological pest control. Unlike eggs, which require a hatching period, these second-instar larvae arrive hungry and ready to hunt immediately upon release. Known in the industry as "Aphid Lions," a single larva can consume up to 60 aphids per day. This is the preferred solution for active infestations where immediate knockdown is required to save high-value aroids or nursery stock. By skipping the egg stage, you eliminate the risk of environmental desiccation and ensure 100% of the product is actively patrolling your 6" plants from minute one.

  • Common Name: Green Lacewing Larvae

  • Target: Apex generalist predator; "Search and Destroy" for Aphids and Thrips.

  • Format: Active 2nd-instar larvae in a protective carrier material.

  • Best For: Curative treatment of active pest outbreaks and "hot spot" management.

  • Key Advantage: Immediate impact. Arrives ready to feed, bypassing the 3-5 day hatching window of eggs.

Target Pests

The larvae are apex generalist predators with a particular "seek and destroy" instinct for:

  • Aphids: Every species (Green Peach, Melon, Potato, etc.)
  • Thrips: Aggressively hunts larvae and pupae in the canopy.
  • Mealybugs: Effective against crawlers and younger nymphs.
  • Two-Spotted Spider Mites: Clears "hot spots" where mite populations are peaking.
  • Whitefly: Consumes eggs and sessile nymphs.
Environmental Needs

Because these are active hunters, they are slightly more resilient than eggs, but thrive in:

  • Temperature: 15°C – 32°C (59°F – 90°F).
  • Humidity: 40% – 70% RH. Larvae tolerate lower humidity much better than eggs.
  • Habitat: Best used in dense foliage or "heavy" canopies like Alocasia and Philodendron where they can hide and hunt.
Selection Guide

Choosing larvae over eggs is a strategic decision based on the severity of your pest issue:

  • The "Emergency" Choice: If you see curling leaves or visible clusters of aphids, choose larvae. Eggs take 3–5 days to hatch; larvae start eating in seconds.
  • Guaranteed Success Rate: Larvae bypass the delicate hatching phase. You are paying for active hunters, not potential ones.
  • Precision Targeting: Larvae can be "spot-treated" directly onto a specific leaf or plant that is struggling.
  • Generalist vs. Specialist: While an Aphidius wasp needs a specific aphid host, Lacewing larvae are not picky—they are the best "clean-up" crew for mixed-pest outbreaks.
How to Use

Direct Release: Open the container only when you are next to the plants.

Application: Gently sprinkle the carrier material directly onto the foliage of your 6" plants.

Strategic Placement: Focus on the "hot spots"—under leaves, near new growth, and inside leaf sheaths of aroids.

Timing: Release in the evening or when grow lights are dimmed to prevent the larvae from crawling away from the light.

Dose per 6" Plant: For an active infestation, we recommend 10 larvae per plant.

How They're Shipped
  • Format: Shipped as active 2nd instar larvae in a carrier material to prevent cannibalism during transit.
  • Packaging: Breathable, temperature-controlled containers.
  • Storage: Do not store. Larvae are highly active. Release immediately upon arrival. If storage is unavoidable, keep at 8°C – 10°C for a maximum of 4 hours.

FAQ

What is your Live Delivery Guarantee?

We guarantee that your beneficial insects will arrive healthy and ready to work. Because we are shipping live organisms, we use packaging and expedited shipping to ensure their safety. In the rare event that your order is compromised during transit, please take a photo of the package and contact us within 24 hours of delivery so we can make it right.

Can I use these if I recently sprayed Neem oil or insecticidal soap?

We recommend waiting at least 48–72 hours after applying organic oils or soaps before releasing larvae. While these treatments have no residual "poison," their physical coating can hamper the larvae's ability to move or breathe. Always rinse your plants with fresh water and let them dry before introducing beneficials.

What happens to the larvae after they finish eating all the pests?

If the food source runs out, the larvae will instinctively wander to find more. In a contained indoor environment or grow tent, they may attempt to cannibalize other larvae if they remain crowded. Once they finish their growth cycle (about 2 weeks), they will spin a small, white silk cocoon and pupate.

Do the larvae bite humans or pets?

While they are "lions" to aphids, they are harmless to humans and pets. Occasionally, if a larva is handled or crawls on your skin, you might feel a tiny "pinch" as they investigate if you are prey, but they have no venom and cannot break human skin.

How do I know the larvae are still alive in the carrier material?

Because they are shipped as 2nd instar, they are visible to the naked eye but can be camouflaged by the buckwheat hulls. To check for activity, gently pour a small amount of the carrier onto a white piece of paper; after a few seconds of warmth, you will see the small, alligator-shaped larvae begin to move.

Are these effective for pests in the soil?

No. Chrysoperla carnea larvae are canopy-dwellers. They are biologically programmed to climb upward toward the light to find aphids and thrips on leaves. For soil-borne pests like Fungus Gnats or Root Mealybugs, we recommend pairing these with our Nematodes or Hypoaspis miles.

Will my circulating fans blow the larvae off the plants?

Large, established 2nd instar larvae have strong legs and can hold their own against standard ventilation. However, we recommend turning off high-powered oscillating fans for the first 1–2 hours after release. This allows them to settle into the "crooks and crevices" of your aroids without stress.

Help! I'm overwhelmed

Yeah, it's a lot the first time you're using predatory mites. Please email us at info@fgmnnursery.com and we'll be happy to help!

I don’t see anything moving in my bottle or sachet. Does that mean they’re dead?

Not at all! In fact, go ahead and deploy them.

Predatory mites are microscopic (often less than 0.5mm) and naturally blend into their carrier medium (bran or vermiculite).

  • For Bottles: The mites often huddle in the center of the bottle for insulation during transit.
  • For Sachets: These are "slow-release" nurseries. The mites stay tucked deep inside the breeding media and emerge one by one over 2–4 weeks. Seeing an "empty-looking" sachet or bottle is not proof of a loss; it is simply how they are packaged for maximum survival.
