Use bubble wrap for any breakables.
Make sure to fill up each box to prevent shifting. Use items like newspapers, towels, paper towels or peanuts.
Neatly label the boxes that include fragile items, and place them in the unit towards the front so they don't get shifted towards the wall or larger items that may cause damage.
Don't store electronics in a room that gets below freezing. These subzero temperatures can wipe out your hard drive and ruin your TV.
Place mattresses flat. Standing up a mattress will cause the padding to shift more to one side.
If you are storing small or awkward-sized items, use a shelving unit to maximize space.
If you have a dresser, put stuff in the drawers. Place your brooms, shovels, and rakes in an unused garbage can.
Vacuum seal clothing or bedding.
Make an aisle down the middle of the unit so you can walk freely without tripping or falling.
Label each box. Tip: label by room, contents or breakable.
Place furniture slides under heavy items so they are easy to move around.
Take inventory of your belongings so you can recall what is in your unit.
Dryer sheets placed in boxes and in the corners of the unit will keep pests away, but will also make your belongings smell fresh.
If you're storing your vacuum, make sure the vacuum bag is empty. Particles of old food may attract critters.
Use furniture covers for anything with fabric. Use fitted sheets around a mattress or box spring.
