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.
To kill bagworms, you can use insecticides specifically designed to target caterpillars like bagworms. Make sure to apply the insecticide while the bagworms are still young and active, typically in late spring or early summer. Follow the instructions on the insecticide product carefully for the best results.
Permethrin is effective in controlling bagworms in their early stages, but it may not be as effective at killing mature bagworms. For mature bagworms, manual removal or the use of other insecticides specifically labeled for bagworm control may be more successful.

Bacillus thuringiensis is 'B.t.', which is an organic control of bagworms, caterpillars, hornworms and loopers.
Bagworms are caterpillars that construct protective cases made of silk and debris. They do not bite people or animals as they are herbivores. The main concern with bagworms is the damage they can cause to trees and plants by feeding on their leaves.
Yes, bagworms should be killed since this larval stage of case moths (Psychidae family) can defoliate trees and the chrysalis and the moth stages can cut off internal arboreal fluid circulations with the delicate-looking, super-strong thread by which pupae and adults hang from twigs. It is an unfortunate case of the adult living just long enough to mate and not cause trouble other than leaving behind many eggs that will turn into voracious caterpillars.Any stage in the lepidopteran in question's life cycle may be controlled by manual or mechanical removal while natural enemies include entomopathogenic bacteria and nematodes, ichneumonid parasitoid wasps, parasitic wasps, sparrows and white-footed mice and treatments focus upon the egg and larval stages before mid-summer.
Sprays with the active ingredients of acephate, carbaryl, or permethrin kill bagworms [Thyridopteryx ephemeraeformis]. A spray with the active ingredient malathion kills too. But such a powerful chemical control needn't be considered in most cases.Reluctance likewise may be shown regarding the use of carbaryl. It's the active ingredient in 'Sevin'. It controls bagworms, but at the price of encouraging mites.Whichever the control chosen, timely use of the product is important. The most effective treatment times are late May to mid June. That's because the bags are less than a half inch long, and vulnerable to the active ingredients.Otherwise, Bacillus thuringiensis is an effective control. But once again, timing is everything. The best time range is mid to late June, when the larvae are still young.Additionally, handpicking may be the control, from August to May. The bags should be bagged and burned. Otherwise, they and their eggs will over winter, and hatch in late May.
The description provided sounds like bagworms. Bagworms are moth larvae that create protective cocoons made of silk and camouflage themselves with debris such as twigs and leaves. When disturbed, the bagworm will retract into its cocoon, revealing a small worm-like head poking out. Bagworms can cause damage to plants and trees by feeding on foliage.
The cocoon-looking things in trees are most likely bagworms. Bagworms are moth larvae that create protective cases made of silk and plant material to live in. They form these cases as they feed on leaves and branches, gradually growing larger until they pupate and emerge as adult moths.
It sounds like bagworms. They do not turn into moths or butterflies and can damage on the host plant that they are on.
