Multiple dose poisons Mice must consume several doses over several days before dying. Thus, these poisons are comparatively safe because accidental single doses, unless large, are not likely to kill. These poisons are warfarin, diphacinone, pival, PMP, prolin, fumarin and chlorophacinone. Food baits for use with multiple dose poison Commercial poison baits are available in many stores, or may be homemade. Any bait, commercial or homemade, should be fresh, not readily perishable, and more attractive than the food already available to the mice.
Some excellent baits are corn meal, grits, bread crumbs and rolled oats.
Mixtures of these materials, plus sugar, increase attractiveness. Kitchen grease, peanut oil and fish oil also help, but many cause the bait to spoil faster. Use of poison baits Place poison baits at 8 to 12 feet intervals in areas where evidence of mice is seen but where children and domestic animals cannot reach them and where there is no danger of contaminating food or feed. Odors Putrification odors can be prevented only by removing the dead mice. Special deodorants available from pest control firms or industrial and chemical supply firms will reduce odors.
