The past few seasons, bagworms have been particularly problematic and populations are not expected to decline soon. These perennial insect pests infest evergreen species and several deciduous species including black locust, honeylocust, and sycamore. Understanding their control can help protect your plants from damage and even death. Visit the Lancaster County Extension website to learn more about bagworms.
Included in the website is a helpful handout on bagworms and this video.
