You need one item.
That item is salt.
Step 1: Small amounts cast around
Every three feet or so, throw a pinch of salt.
Carpeted or uncarpeted. Floorboards or tiles - It doesn't matter.
Walk around inside of each room, throwing a pinch of salt down as you walk, every step or so.
Kitchen, bathroom, bedroom, laundry, garage - each room.
Then the hard-to reach places, just a pinch will do: on top of and inside kitchen cupboards, and behind the refrigerator, drawers, under sinks, all shelves and clothes wardrobes.
In the bathroom, pour a little down the sinks and drains.
That's it. Your done.
You won't see them again.
