mealybug control

Mealybugs are common pests across agricultural crops, interiorscapes, greenhouses, and home gardens, with different species (such as citrus mealybug, longtailed mealybug, grape mealybug, and obscure mealybug) varying in behavior, habitat, and susceptibility to control. Accurate identification of the mealybug species present is an important first step in building an effective biological control program. Cryptolaemus montrouzieri (mealybug destroyers) are the most widely used and effective predator, consuming all life stages of mealybugs and performing especially well in warmer, protected environments. Lacewing larvae provide broad-spectrum predation and are useful for early infestations and mixed pest situations. Long-term success also depends on ant management, as ants protect mealybugs in exchange for honeydew and can severely limit predator effectiveness. Cultural practices that reduce dust, excess nitrogen, and plant stress, along with targeted use of non-toxic tools such as fungal biopesticides or oils when needed, help bring populations into balance. Early intervention and consistent releases are key to achieving sustained control.
