NO BOTTOM BLUE BASE WITH THIS ITEM. Large Black Rubber flap & sock kit only.
Large rubber flap with Insecticide Sock Kit. It replaces the large rubber flap on the top of the Pride of the Farm Dura Bull & Industruca Bull Mineral Feeder. As one of the animals lifts the flap to eat mineral, the solution wicks away from the fibers to treat the face, head & shoulders. Use EPA approved insecticide. Always follow the instructions. Either diesel fuel or mineral oil can be used as a carrier. Re-charge the sock with about one gallon of mix every 7 to 10 days during fly season.
