Giant Hogweed: Identification and Control

Giant hogweed is dangerous. Skin contact with its sap in the presence of sunlight can result in severe burning and blistering (Nielsen et al. 2005). For this reason, giant hogweed is both a Virginia and Federal noxious weed (USDA APHIS, VDACS). If you are exposed to the sap, immediately get out of the sun, wash with soap and water, and if a reaction begins to occur, seek immediate medical attention (Hyypio and Cope).
