A favorite "good bug," ladybugs have been a popular beneficial insects for the past 20 years. When released at sundown (because they don't fly at night), ladybugs eat aphids, mealy bugs, scale, leaf hoppers, and other destructive pests. And they keep on eating until the bad guys are gone, laying their own eggs in the process. When new pests arrive, fresh ladybugs will be waiting. You will love them because ladybugs really work, plus they will be doing something favorable for the environment. LADYBUGS (Hippodamia convergens)
USE: Ladybugs prefer to eat aphids and will devour up to 50 a day, but they will also attack scale, mealy bugs, boil worm, leaf hopper, and corn ear worm.
