July and August are the periods when bagworms are active. The following resource offers recommendations for insecticides that control bagworms. https://extension.entm.purdue.edu/publications/E-27/E-27.html

If you only find a few bagworms on the plants, hand removal and drowning in a bucket of soapy water would be easier than chemical control.
