guinea hen
Guinea hens They control deer ticks, wood ticks, grasshoppers, box elder bugs, flies crickets, and all other insects. Their call will discourage rodents and will kill and eat mice and small rats. They will kill snakes, and will alert you to anything unusual. Some people who live in areas where snakes are common tell how their Guineas will spot and find snakes so they can kill them before they cause any harm, and the Guineas themselves will kill snakes.
