this is quite possibly the best fly atractant you will ever buy unless your buying it in the biger bottle haha buy it you wont be dissapointed but dont get it on you unless you want the flys to like you ps it stinks to high heaven
Flies love this smelly stuff, but once you put it in your trap you don't really smell it in your barn. I have used these the past 3 years and they really work. You just have to keep an eye on the water level in your trap so that they don't dry up.
Word of caution: DON'T let it get on your skin. It smells horrible and is hard to get off once you get it on yourself.
