Has anyone heard of or used THE FLY KILLER KOVER? I've just seen an advertisement for this. It is a mineral feeder with a reservoir on the top cover of the mineral feeder. The reservoir holds insecticide that wicks down onto the underside of the top cover. When the cattle go for minerals they also treat themselves. the website for this is www.flykillerkovercom. Just wondering if anyone has feedback on the product.
