What can you use to kill bagworms?

Gloved hands, hosed sprays, mechanical tools and non-organic and organic treatments are options that can be pursued to kill bagworms. The insects in question (Psychidae family) can be controlled best at the egg and hatchling stages with horticultural oils and insecticidal soaps. Minor infestations within comfortable, safe arm's reach respond to removal by gloved hand, hosed spray and mechanical tool into soapy water-filled buckets whereas a number of organic (such as Bacillus thuringiensis) and synthetic (such as acephate, bifenthrin, carbaryl, cyfluthrin, deltamethrin, fluvalinate, permethrin) exist, particularly in the hands of International Society of Arboriculture-certified arborists.
