How can potato beetles be controlled?

Companion planting, diatomaceous earth, horticultural oils. pesticide schedules, removal by gloved hand or mechanical tool into soapy water-filled buckets, row covers, sanitation, and scratchy organic mulch are ways to control potato beetles. Catnip, chives, garlic, green beans, and nasturtiums have reputations as insect pest repellent plants in general and of potato beetle unfriendliness in particular. The insects in question (Leptinotarsa decemlineata) tend to develop quick resistance to pesticides even though garlic sprays and insecticidal soaps against immature and mature stages, horticultural oils against eggs, and sprays with the active ingredients azidirachtin, esfenvalerate, pyrethrin and spinosad are considered still effective potato beetle controllers and killers.
