Chrysoperla rufilabris – Green Lacewing Larvae – Bottle of 1,000

Green lacewings (Chrysoperla rufilabris) are aggressive predators of aphids and many other soft-bodied pests. In their larval stage, lacewings are especially effective because they immediately seek out prey, delivering fast knockdown of infestations. CHRYSOforce™ R ships as active larvae for quick release and immediate impact.

How It Works

• Lacewing eggs are incubated at the insectary and shipped after hatching.

• Larvae actively search for food and attack a wide range of pests.

• They use hooked jaws to pierce prey, inject digestive enzymes, and consume the liquefied body.

• After 10–14 days of feeding, they pupate and later emerge as non-predatory adults.

Targets These Species

Green lacewing larvae feed on over 200 soft-bodied insect pests, including:

• Aphids

• Thrips (larvae and eggs)

• Whiteflies

• Mealybugs

• Scale insects (young stages)

• Moth eggs and small caterpillars

Ideal Conditions

• Temperature range: 67–90°F (20–32°C)

• Best practice: Introduce early at the first sign of pests

• Feeding window: 10–14 days as larvae

• Storage: Do not cold-store. Release immediately upon arrival

Application Instructions

Bottle / Bulk Bag

• Contains lacewing larvae mixed with rice hulls for easy distribution.

• Release the same day received.

• Gently sprinkle contents over the target area.

• Bulk bags include a scoop for measured application.

Hexcel Rearing Frames

• Larvae develop in individual cells under organdy covers.

• Peel back material slowly and tap larvae directly onto plants.

• Place spent frames near plants so any remaining larvae can crawl out.

• Release the same day received (no later than the following day).

Release Rates

Rates vary depending on pest pressure:

• Preventative: 1–3 larvae per 10 sq. ft., monthly as needed

• Low infestation: 2–5 per 10 sq. ft., bi-weekly, 2–3 times

• Medium infestation: 4–8 per 10 sq. ft., weekly, 2–4 times

• High infestation: 1 larva per sq. ft., bi-weekly, 3–5 times

• Maintenance: 1–2 per 10 sq. ft., every 3 weeks, ongoing

• Garden use: 60–90% of above rates

• Acre+ scale: 20–50% of above rates

Notes:

• When using eggs, multiply rate ×5

• When using adults, divide rate ÷4

• Cannabis growers typically require higher release rates—contact us for crop-specific guidance

Where to Use

• Greenhouses and high tunnels

• Outdoor gardens and landscapes

• Orchards, vineyards, and nurseries

• Hydroponics, aquaponics, and grow rooms

• Container plants and interiorscapes

Storage

• Release immediately upon arrival. Do not refrigerate

Quick Tips

• Lacewing larvae provide faster control than eggs, since they are ready to feed immediately

• Reintroduce every 10–14 days to maintain control

• Best results when released directly onto infested plants

• Safe for use with most other beneficial insects
