Abstract
A rodenticide bait block has a keyhole-shaped groove which can be formed by extrusion. A fastener, such as a nail, can be passed through the enlarged inner end of the groove and used to fasten the bait block to a surface. Various configurations are used for the external surface of the bait block to provide additional biting edges.
