unicorn, can't vouch for B n Q , but if it's not got a high percentage of Warfarin in the ingredients, forget it.
As I've mentioned already, warfarin is an anticoagulant, if the rat eats the bait it causes internal hemorrhaging. Early signs that they have taken the bait is, the droppings are in a liquid form. Twenty odd years ago the bait had a purple dye in it, if your bait has been successful , you will see this colour splashed along the runs.
