Abstract
This invention relates to parafinized rodenticide bait blocks in general and, more specifically to the actual form of these bait blocks. The invention concerns itself with the physical construction and shape of the block and will provide a more effective rodenticide by providing a bait block that will have a continuous biting surface that a rodent such as a mouse or rat can knaw at at all times as the block is being consumed. The use of this block provides the user with an individual and metered portion of bait designed to be more effective in eliminating household rodents such as Norway Rats, Roof Rats and House Mice and will, by its use, insure the total consumption of the bait block, thereby providing increased efficasy of the block and greater safety in the use of these poisoned blocks because less residual bait is left behind.
