A cattle scrubber comprising a frame which defines a geometrically shaped treatment zone, a cylindrical feeder barrel located in each corner of the treatment zone, and an elongated, flexible livestock insecticide applicator, which extends around the periphery of the treatment zone. The frame comprises a plurality of interconnected, elongated rigid ground engaging members which intersect at their ends to define the geometrically shaped treatment zone, and a plurality of rigid, elongated upstanding members, one of which is located at each corner intersection of the ground engaging members. Each feeder barrel is located near one of the upstanding members and provided with a feeder opening which is arranged to face inward into the treatment zone. An arcuate bracket member attached to each of the upstanding members is shaped to engage against the cylindrical sidewall of the feeder barrel. A rigid brace member extends angularly between each pair of transverse, intersecting ground engaging members near each corner intersection. The feeder barrels are retained in position, with their feeder openings facing inward into the treatment zone, by fastening the feeder barrels to the bracket members and the brace members. The insecticide applicator is suspended in an arc above the ground between the upper ends of each opposing pair of upstanding members. The insecticide applicator encloses the feeder barrels within the treatment zone such that the cattle must step under and brush against the applicator in order to obtain feed from the feeder barrel.
