A method for treating equine manure involves contacting the manure with sodium bisulfate, preferably at a level of at least 50 grams per square meter of surface. The sodium bisulfate is preferably applied at least once per week. Another embodiment is a method for treating the manure with a material to reduce the pH of the manure, preferably to a pH less than 5. A related embodiment is a method for treating the manure with an acid to reduce the number of flies in the area around the manure, preferably to less than 25% of the number of flies in the same area without the treatment. Another embodiment is a method for treating the manure with a material to reduce the ammonia level in the air above the manure to less than about 2 parts per million.
A method for reducing the number of flies in an area containing equine manure comprising contacting the manure with a dry acid to reduce the pH of the manure at least about 3 pH units to a pH less than about 5.
A method for reducing the number of flies in an area containing equine manure on a surface, comprising applying a dry acid on the surface at least about once per week, to reduce the number of flies in the area to less than about 25% of the number of flies in the same area without application of the dry acid.
A method for reducing the number of flies in an area containing equine manure on a surface, comprising applying sodium bisulfate on the surface at least about once per week to reduce the pH of the manure by at least about 3 pH units to a pH less than about 5.
