The Fly Killer Kover will rid your herd of face fly and pink eye problems using a pour-on or spray insecticide recommended by the manufacturer for back rubber application.
Warning: Do not use grubicide or a systemic insecticide with The Fly Killer Kover.
Adapter kits are available for Applegate, Bull Master, Behlen, Brower, Sioux, Vigortone, and Vita-Ferm three compartment, poly, mineral feeders.
The unit will also provide acceptable horn fly, lice, tick and mosquito control using synergized Prozap Insectrin Pour-On. This is a premixed, ready to use 1.00% permethrin, safe on beef and dairy cattle. Just pour the insecticide into the one quart reservoir centered on top of the kover and your fly control program has just been launched. The insecticide empties from the reservoir in less than 24 hours, saturating the felt. Refill the reservoir weekly or as needed. If you get a lot of drippage of insecticide off the outside edge on the ground, try filling the reservoir less often or not as full.
The kover is a 38 inch diameter urethane weathershield with a 1/4 inch thick polypropylene felt disc bonded to the underside. Mineral in the 150# capacity Mann Poly feeder entices the livestock to nose under the kover and thus the face, head area and shoulder contact the insecticide saturated felt and are self treating themselves almost daily. This unit must be the only source of mineral. You can raise the kover upward to add mineral by grasping the tab on the edge of the kover. Do not overfill mineral. Livestock should reach down into the feeder to get maximum coverage on head and face. To use block mineral, break the block into softball size chunks.
We recommend up to 30 cow calf pair or 40 yearlings per unit and provide effective fly control.
