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.

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.
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.

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).
