Mealy Bug Destroyers are imported help that has successfully controlled a pest, making plants everywhere very happy.





The unique white 'hairs' on this tiny bug often draw attention from people. These larvae are extremely useful in pest management. Their name describes both what they eat and what they do to their prey's population.

This species was deliberately imported from Australia in 1892 to help control mealybug infestations on California citrus groves. Mealybugs are cottony looking insects that suck a plant's juices, weakening them, possibly to death. Their abundance was having an economic impact in the agricultural industry. The introduction of the Mealybug Destroyer was successful and, today, it is bred and sold everywhere in North America.

Adult mealybug destroyers look like black lady beetles with brown heads. If they are present in your garden, they are doing your plants a great service.
