Green Lacewing Larvae
10% off your first 4 orders, then 15% off every order after.
Heads up—this is just an estimate. We only ship when the bugs are happy and ready to travel (Mon–Thurs). If a colony needs a beat to peak, or we're propagating a fresh batch, your order might hold up to a week. Treatment bottles jump the line when you've got an active infestation.
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.

How to Use
How They're Shipped
Hatch is hours away. Be ready.
Lacewing larvae ship as pre-incubated eggs. They're timed to hatch within 24 hours of delivery, instead of the 7-10 days regular eggs can take. Why? Lacewing larvae are aggressive predators from the moment they hatch, and they don't distinguish between aphids and their siblings. Shipping incubated eggs keeps the colony intact in transit; hatching just as you're placing them onto your plants. Plan your release for the same day or the next morning.

01
Open the box right away
Bring the package indoors as soon as it arrives. Don't leave it on a hot porch, in a cold mailbox, or in direct sun. If your delivery was delayed by a day, the eggs are still fine — the incubation timing has a small margin built in to absorb a one-day delay.
-
02
Sprinkle the carrier across your plants
You won't usually see the eggs themselves, and you'll see the carrier media they're mixed in. Sprinkle across affected plants, into leaf axils, along stems, and into the inner canopy where aphids cluster. Spread thinly across as many plants as possible. The single most important thing is distribution: concentrating the mix in one spot means the larvae hatch into competition with each other instead of food. Wide and thin is the rule.

03
Watch for results over 1–2 weeks
Newly hatched larvae are tiny (about 1mm), pale brown, and alligator-shaped — they'll feed on aphids, mealybugs, thrips, and other soft-bodied pests for two to three weeks before pupating. Aphid populations typically start dropping within the first week. If pest pressure isn't easing by week two, that's when to email us.

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.

Native vs Invasive Ladybugs
Most ladybugs you'll encounter are red with black dots — and that description fits native, introduced, and invasive species equally. Here's how to actually tell them apart, what the harlequin ladybug has been doing to native populations, and where the real ecological concerns are.
