Although Lakeside Storage hasn't encountered many problems with mice in units, it's always smart to take precaution to prevent them. One of the best ways to ensure they don't take a liking to your unit is to not store any food in your units. A dry home and free food is enticing to even the smallest of creatures! We also suggest placing rodent poison somewhere inside your unit. That way any unwelcome critter who could potentially wander into the wrong unit wont be a long term guest! Our office sells packets of Havoc Rodent Poison for only $3. Another option is to soak some cotton balls in peppermint oil and place them strategically around your unit. The smell of peppermint will have any rodent running in the opposite direction!
