You will receive the small bottle, NOT the green jug. Rebottled into a smaller size. 10ml will make one gallon, or four 1-quart treatments. This is a great size if you have a small to medium flock, and need multiple treatments that include spraying a larger coop. If you're spraying the chickens only and not the coop, 10ml will treat several dozen chickens. The active ingredient is a soil bacteria (spinosad). A copy of the product info/instructions is included. Do not apply anywhere near water or dispose of where it can seep into water, as this product is extremely toxic to mollusks. Proven to be effective against red mites, northern fowl mites, darkling beetles, hide beetles, house flies (adults and larvae), stable flies, and little house flies. 10ml is packaged in a recyclable plastic squeeze bottle. Shipped in a 100% recycled cardboard box. Mixing guide included. Need a smaller size? I also carry 2.5ml bottles. If you have any questions, please do not hesitate to ask, and thanks for looking!
