Chrysopa (Chrysoperla carnea) — Green Lacewing Larvae for Aphid & Mixed Pest Control
Chrysopa contains larvae of Chrysoperla carnea, a highly effective generalist predator for aphids and other soft-bodied pests. These larvae are aggressive hunters that crawl across plant surfaces, piercing and consuming prey in all life stages—eggs, larvae, and soft-bodied adults. Chrysopa is chemical-free and safe for use in any growing environment including greenhouses, nurseries, orchards, flower beds, interiorscapes, outdoor landscapes, indoor plants including houseplants and more.
Use For
Chrysopa larvae feed on many pests encountered on foliage, including:
Aphids (all common species)
Mealybugs
Thrips (larvae and eggs)
Whitefly eggs and pupae
Spider mites (all active stages)
Lepidopteran eggs
Other small soft-bodied pests
How It Works
Mode of Action: Larvae pierce prey with curved jaws and consume body fluids completely
Behavior: Larvae crawl along plant surfaces to find and feed on pests
Visual Effect: Pest numbers drop as Chrysopa larvae feed; shriveled skins may remain
Feeding Rates
Second-instar larvae (included in Chrysopa) consume ~20–40 aphids per day under optimal conditions
Third instar larvae can consue ~30–60 aphids per day
Larval feeding lasts ~14–21 days before pupation
Total consumption across the larval stage can exceed 400–500 aphids, plus additional thrips, mealybugs, and spider mites when encountered under optimal conditions.
Application Notes:
Rotate gently before use
Distribute larvae directly onto foliage or into Dibox release boxes near hotspots
Best Working Conditions
Temperature: Effective from 68–86°F; cooler conditions slow development
Humidity: Moderate RH supports activity and survival
Compatibility Guidance

What to Expect
Chrysopa larvae begin hunting immediately after release. Control builds as larvae consume aphids and other pests. Reapply per scouting results to maintain control as needed.
Recommended IPM Pairings
Aphipar-M (Aphidius colemani): Complements Chrysopa by parasitizing aphids while larvae provide direct kill
Isarid® Mycoinsecticide: Adds fungal control for mealybugs and soft scales
Dune™: Improves plant resilience against sucking pests
Essential Oil Knockdown (e.g., neem-based): For pre-release reduction of heavy pest populations; apply beneficials after residues dry
Frequently Asked Questions
Long-term storage, i.e. more than 48 hours, is not recommended. Apply promptly after receipt. Our products are shipped fresh for immediate use to ensure maximum performance. If needed, keep in a cool, dark, dry place for up to 1–2 days; longer holding reduces effectiveness and quality.
Yes, Chrysopa larvae feed on thrips, mealybugs, whiteflies, spider mites, and more.
No, the larval stage of Chyrsopa is the predatory stage. Chrysopa contains larvae only.
Feeding starts immediately. Visible reduction occurs as larvae consume prey.
