Horticultural oils against eggs, insecticidal soaps against immature and mature stages, and natural enemies are ways of killing ladybugs in Maryland. The insects in question (Coccinellidae family) do not hold protected status even though the natives need all the help that they can get against the aggressive, invasive Asian lady beetles (Harmonia axyridis) that are cannibalizing American species. Natural enemies include assassin bugs, brown lizards, crows, dragonflies, fungus, martins, mites, parasitic wasps, swallows, swifts and tree frogs.
