How do I know which rodenticides contain ingredients to keep the rodents from smelling dead once they die?
For example if they die in an attic or wall void?
There is not a rodenticide on the market that stops a decomposing rodent from smelling after they die. There are a lot of "old wives tales" that suggest that there are rodenticides that will make a rodent exit the building after they eat the bait, leave in search of water or dry up immediately after death and leave no stench behind. Unfortunately, none of this is true. If a rodent dies, it will smell as it decomposes and the rodent will die wherever it succumbs to the poison which is likely to be is an inaccessible area where the rodent has been nesting. We recommend using glue boards, snap traps or multi-catch mouse traps indoors, so you will know exactly where the mouse has died and can remove it with ease.
