Using rodenticides around the home is the most common method for controlling rats and mice. Although extremely effective at killing rodent pests they can also be harmful to non-target species including pets, wildlife and people. Always read the instructions before placing baits and immediately remove carcases to minimise risk of secondary poisoning. The Big Cheese Home Choice All-Weather Block Bait is a paraffin wax block for the control of rats and mice. Suitable for indoor and outdoor use, the blocks keep the bait fresh and palatable, even in wet weather and avoids spillage when setting, so it is safe for use around food storage areas.
