Do rats smell after being poisned if they die under floor boards?

Yes, rats can emit an unpleasant odor after dying, including those that have been poisoned and die under floorboards. The smell is typically caused by the decomposition of their bodies, which can attract other pests and create hygiene issues. The intensity and duration of the odor can vary depending on environmental conditions and the time it takes for the body to decompose. It's advisable to locate and remove the carcass if possible to mitigate the smell and potential health risks.
