Description
PLEASE READ SHIPPING POLICY BEFORE ORDERING.

Prices include handling & shipping by 2nd Day Air. IMPORTANT - IF DAYTIME TEMPS WHERE YOU LIVE ARE ABOVE 75 DEGREES AT TIME OF ORDER, WE RECOMMEND SHIPPING BY NEXT DAY AIR (ADDITIONAL $21) TO SAFEGUARD AND GUARANTEE YOUR ORDER.

Known as "aphid lions", lacewings are nocturnal predators. They are available as eggs, larvae, and adults. As larvae, lacewings are opportunistic predators and they keep aphids and other soft-bodied pests — for example long-tailed mealybugs and whiteflies — at bay.

How it works
Female adults actively seek out colonizations of aphids. Mated females then lay their eggs among the aphids. The eggs hatch into larvae which then devour the aphids.

General usage
Greenhouse, fields, interiorscapes, orchards, and gardens. Use the eggs when you're in no great hurry to get rid of the aphids. Use the larvae for quick results. Use the adults as nomadic predators, ideal for tree applications.

Directions for use
Use the larvae when aphids (or other target pests) are present. Use the eggs as an inoculum only, most often used in gardens. The pupae and adults are for orchard applications only. Use the adults only in row crops.
For more information, see detailed instructions.

Advisories
IMPORTANT - LACEWING LARVAE IN A BOTTLE MAY DEVOUR EACH OTHER DURING STORAGE OR EXTENDED DELIVERY PERIODS. WE RECOMMEND SHIPPING BY NEXT DAY AIR OR YOU CAN ORDER LARVAE IN THE PROTECTIVE HEXCELL PACK.

Larvae are shipped in rice hulls. The larvae are very small and slow moving and are also about the same color as the rice hulls - so they are very difficult to see in contrast to the rice hulls. Even then, they are quite difficult to see.

For optimum results, have lacewing larvae shipped by Next Day Air and release them as soon as you receive them.

Application rates
Prevention: 1-3 per sq.yard - release monthly as needed
Control light: 2-5 per sq.yard - release bi-weekly x 2-3
Control medium 4-8 per sq.yard - release bi-weekly x 2-4

Maintenance: release 1-2 per sq. yard - tri-weekly indefinitely

Comments: above rates are for larvae. For eggs, multiply rate by 5, adults divide by 4.
