The Unexpected Way Salt Can Keep Mice Out Of Your Home
Salt is poisonous to
mice because it severely dehydrates them. Instead of traps, you can use salt as a natural poison and ensure they don’t die directly in your house.
Sprinkle liberal amounts of salt directly on areas where you know mice are. If they don’t consume it, you may have to combine it with a food item that mice are naturally drawn to.
Peanut butter is one food that mice enjoy, so spread some on a paper towel or dish and then generously salt it. That should be enough to attract mice to the bait.
They will instantly start looking for water to counteract the salt. Ensuring no available water sources will drive them out of your house before they perish.
