While there are cases where people seem to favor bleach as a mice prevention solution because of the strong smell – in most situations, it does not help at all. However, it can be sprayed on the mouse droppings to kill harmful bacteria.Fun fact: Thomas Leung and Seung Kim found that dilute-bleach baths could minimize the processes that age and damage skin in mice. After reading how scientists have given baths to mice and had a repairing effect on their damaged skin – bleach solution for mice control does not sound like the wisest choice. And we doubt that it can work as a mice repellent for the majority of the cases.
