Many people ask why bother to try control Hogweed at all? What harm can it do?

The sap is corrosive on contact with Human skin (and your pet dogs) and causes horrendous blistering, and scaring. The area of skin that has been in contact with Hogweed is then photosensitive for up to 6 years after the initial contact event – meaning that exposure to sunlight can re-activate the burn for up to 6 years, so the victim needs to keep the area of burnt skin covered for 6 years….. not an easy thing to do if you get a burn on your hands or face.
