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.
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.
In trees
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.
Spruce trees should be sprayed for bagworms in late spring to early summer, typically between late May and early June, when the larvae are actively feeding and are still small. It's essential to apply the treatment before they form their characteristic bags, as this makes them more challenging to control. Always check local guidelines and consider using an appropriate insecticide that targets bagworms effectively.
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.
Bagworms are the larvae of moths belonging to the family Psychidae. Once they complete their larval stage, they pupate inside the protective silk bags they've created, eventually transforming into adult moths. These adult bagworms are typically small, winged insects that emerge from their bags to mate and lay eggs, continuing the lifecycle.
