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.

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.

Bacillus thuringiensis is 'B.t.', which is an organic control of bagworms, caterpillars, hornworms and loopers.
It sounds like bagworms. They do not turn into moths or butterflies and can damage on the host plant that they are on.
I have figured out that they are called bagworms.
The cocoon is that of a "bagworm," a type of moth. The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of the Lepidoptera (butterflies and moths).
Yes, Sevin kills bagworms.Specifically, it is important to keep in mind the forms of the control and the pest. Sevin dust is most effective before the bagworms (Psychidae family) exceed lengths of ½ inch (1.27 centimeters) or more. Other options will include removal by hand and treating with Bacillus thuringiensis (Bt).
Bag worms are so named because they make small bags to live in that hang from a tree. They are not poisonous but will quickly destroy the tree they latch onto if they are not removed.
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.
