Mike Raupp, an entomology professor at the University of Maryland, explains in this video how, like a crime scene investigator, you can use clues to find out what types of insects are causing damage in your garden. Look for telltale signs like chewed leaves, discoloration, distortion, dieback, and insect products. This video is brought to you by the Home and Garden Information Center, part of University of Maryland Extension, which provides resources and encourages people to start their own food gardens (http://www.growit.umd.edu).
