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.
In trees
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.
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.
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.

Yes, arborvitae trees can attract bugs such as aphids, spider mites, and bagworms, which can potentially harm the tree if not controlled. Regular monitoring and proper care can help prevent bug infestations on arborvitae trees.
you kill a lot of things and you kill the trees
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.
i want to help with this 1.you can kill trees by oil
Bacillus thuringiensis is 'B.t.', which is an organic control of bagworms, caterpillars, hornworms and loopers.
