The black widow spider is one of the most poisonous of all animals -- its venom is fifteen times more potent than that of a rattlesnake. Yet it is much more common around human habitations than poisonous snakes, often being found in basements, attics, barns, garages, and other buildings. It pays to know more about the black widow, and this book is a clear and useable account of practically all that is know about this deadly and dangerous animal.
