Green
Lacewings
(Chrysopa rufllabris) are another of the walking "garbage
disposal" appetites of the insect world - if it's an insect
or egg that fits in their mouth, they'11 eat it. That's why
green lacewings are suggested for control of many pests, both
outdoors and in the greenhouse, when there's nothing more specific
available.
Lacewings immediately begin eating pests after hatching. Looking
like miniature "alligators", they grow to almost 1/2"
long over 3 or 4 weeks, consuming 400+ aphids or other pests
in the process. After that, they pupate into a beautiful adult
insect, feeding only on nectar and pollen from flowers. Unless
adults find nectar and pollen sources, they won't lay more eggs,
so you may need to reapply them for good pest control.
We
suggest using 4000 eggs per backyard or 5000-50,000 acre (depending
on infestation), repeat every 2 weeks through the pest season.
