Bagworm Treatment Control Products

The bagworm caterpillars make distinctive little spindle-shaped bags that we find hanging from twigs and leaves from trees and shrubs. The female moths cannot fly but the larvae of the bagworm can disperse. This can make bagworm treatment tricky. 


They create very small caterpillars that can spin fine strands of silk and then get carried off by the wind. The bagworm will feed for about six weeks, and in that time the bag will be enlarging. When you have large populations or heavy infestations over many years, they can cause plant death. To control your bagworm problem there are two options. One can handpick small amounts from area trees or shrubs. Bagworms typically prefer juniper trees, spruce, pine and cedar trees. Plan for Fall or Winter, and sometimes even early Spring, as the best times to manually remove them.

This is also prior to egg hatchings, which is the only time chemical control is proven to be effective. This is a great, although time-consuming method, to getting rid of them. The other option is chemical control. For chemical control use a general purpose insecticide that is labeled for bagworms. The best time to apply is when the larvae are still small, smaller than 1/2 inch, which is about early June in most places. This time period is when they are most susceptible to the insecticides. Look for products such as Acephate or Carbaryl, Pyrethroids such as Bifenthrin, Cyfluthrin, Gamma-Cyhalothrin, and Permethrin products.
