I have bagworms in an umbrella tree and I have cut off ans destroyed the small branches. Some bags are up higher than I can reach and am looking for a product that I can spray with a hose end sprayer and not injure my lawn or nearby shrubs. Any suggestions? I have heard of products containing BTK. The tree in question is about 20-25 ft and has a rock garden with shrubs and flower garden below.
