Two beneficial insects in one package. Ladybugs, a favorite "good bug", when released at sundown (because they don't fly at night), eat aphids, mealy bugs, scale, leaf hoppers and other soft-bodied pests. Green Lacewings are a natural enemy of many pests. The eggs hatch into tiny larvae, known as "Aphid Lions" because of their voracious appetites (devouring as many as 1000 aphids per day). They remain larvae for up to 21 days, crawling around and eating spider mites, thrips, whitefly larvae, moth eggs and other soft-bodied pest.
