We've turned our doe estrous into a foam for greater scent dispersal and long-reaching effectiveness. Foaming estrous urine clings where it is applied. Spray nozzle allows for no-mess application. Doe estrous is essential when you're hunting bucks during the rut. CODE BLUE has found a way to make it even more indispensable. By converting doe estrous into a foam product, we've increased the scent's surface area to eight times the volume of liquid. The result is greater scent dispersal and long-reaching effectiveness. Our foaming estrous urine doesn't run off where it's applied, instead it clings. No-mess spray nozzle allows easy application to limbs, tree trunks, brush, wherever.
