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.
Harvested forage is usually stored as hay or silage. Hay is stored at a moisture level below 20 percent. When farmers store hay at moisture levels higher than 20 percent, the forage becomes moldy and may spontaneously catch on fire. For best long-term storage, hay should be sheltered from rain or snow.
