| Mealybugs have oval bodies with overlapping soft plates and a cottony white covering. They are related closely to scale insects, but do not attach to a plant and can moved around very slowly. They can stunt a plant or kill it by sucking its juices. They excrete a honeydew which can cause a black, sooty mold.

| ==Control==
| |
| Note that mealybugs have a symbiotic relationship with [[ants]], which may need to be addressed to clear your mealybug infestation.
| |
| | |
| ===By hand===
| |
| Mealybugs are serious [[houseplant]] pests around the world, and outdoors they are troublesome pests wherever winters are mild. When you spot an infestation, indoor or out, you can just dip a cotton swab in rubbing alcohol and dab the mealybugs directly with it by hand.
| |
| | |
| ===By hose===
| |
| You can hose off plants every 2 weeks with jets of water (or [[insecticidal soap]]) in order to blast away as many of the mealybugs and their eggs as possible, as well as the [[black soot]] which deters natural predators.
| |
| | |
| ===Natural predators===
| |
| [[Ladybugs]] (Ladybird beetles), [[cryptolaemus beetles]] and [[lacewings]] all are natural predators of mealybugs. They can be bought commercially and released to help control the population.
| |
| | |
| ===Chemical control===
| |
| Chemical pesticides known to be effective against mealybugs include malathion, diazinon, acephate, or [[horticultural oil]].
