A favorite good bug and alternative to chemicals, ladybugs eat aphids, mealybugs, scale, leaf hoppers, various plant eating worms and other destructive soft bodied pests. Most effective when released at sundown because they don't fly at night, ladybugs keep eating until the bad guys are gone, laying their own eggs in the process. Each container includes 1,500 live ladybugs. Gardeners simply mail in the postcards or register online to have their insect orders shipped to their doors at no extra cost.
