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.

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.
Mite Matters
The Beetle That Looks Like Its Prey
The larvae of Cryptolaemus montrouzieri look so much like mealybugs that growers routinely try to wipe them off their plants. That's the beetle they just released, eating the pest they paid to eliminate. Here's how to tell them apart — and everything else you need to know before you release the most effective biological mealybug control in existence.
They Started the Moment You Released Them. You Just Can't Tell Yet.
You released the predatory mites three days ago and the spider mites are still there. The nematodes went in a week ago and the fungus gnats are still flying. This is the moment most growers reach for a spray — and it's usually the wrong move, because the beneficials have already started. Here's what's actually happening after a release, and how to read the signs that it's working.
Whitefly Treatment That Doesn't Wear Off
Spraying whiteflies knocks back the adults you can see. It doesn't touch the eggs. The eggs hatch, the nymphs are harder to kill, and three weeks later you're back where you started — except the population is slightly more resistant. Here's how predatory mites and Orius break that cycle by targeting the stages your spray misses.
