<p>The disclosure herein describes an apparatus (10) which is adapted to be mounted adjacent to an entranceway (14) for spraying animals (16) passing through the entranceway (14). It comprises an inverted U-shaped tubular structure with an upper portion (28) and opposite side portions (24,26), each portion including a vapourizing unit (30,32,34) and connecting members (36,38) each having one end received in the vapourizing unit (34) of the upper portion (28) and an opposite end portion in the vapourizing unit (30,32) of an adjacent one of the side portions (24,26). A unit is mounted to the structure for detecting the presence of an animal (16) in the entranceway (14) and conduits extend in the connecting members (36,38) and the vapourizing units (30,32,34) for directing the spraying fluid from a remote reservoir (42) to the vapourizing units (30,32,34). <IMAGE></p> |
