Show as one of the safest poisons to use, from the human standpoint; stand-point; also it holds promise of wiping out the entire rodent population cmpletely. "Warfarin" is the name of the new death-dealing substance. It was developed at the University of Wisconsin in the laboratories of Professor Karl Paul Link, and is now available through ro-denticide ro-denticide manufacturers. SLOW POISON Wartfarin. is tasteless and odorless; also, it is slow-acting and relies upon the cumulative effects of small quantities consumed con-sumed over a period of days. Rats taking the poison show no immediate effects. However, they eventually become drowsy, and begin to walk with a slow and measured gait.

There is no dash for water, there are no convulsions, and the bait then remains effective to keep stray rats from again populating the area. One major advantage of Warfarin War-farin rodenticides is their relative rela-tive safety. Since this chemical relies upon cumulative doses for results, there is little chance that enough bait will be taken by humans, pets or domestic animals to cause serious poisoning poison-ing effects. Out of the several hundred natiorwwide tests made on Warfin, no case of accidental acci-dental human poisoning has been reported, the extension entomologist en-tomologist indicated.
