The venom of the black widow spider contains poisonous chemicals that make people sick. Black widows are found throughout the United States, mostly in the South and West. They are usually found in barns, sheds, stone walls, fences, woodpiles, porch furniture, and other outdoor structures.
Some types of grass hay, in dry weather conditions or on dry ground, will be much too dry when baled as small bales using the eight to 15 percent moisture (the traditional rule of thumb) as a guide. Some of this grass hay produces the best quality bales when baled at 24 to 30 percent moisture.
Fire is imminent if interior bale temperatures exceed 175Â°F and fire is present at temperatures greater than 200Â°F. Other symptoms of hot hay or an internal hay fire include a slight caramel or strong burning odor, visible vapor or smoke, a strong musty smell, and/or hay that feels hot to the touch. If any of these symptoms occur, call the fire department immediately.
