Step 1: Eliminate Food and Water
Remove all potential source of food from the premises, such as bird seed and garbage. Routinely harvest ripe fruit and pick up all fruit that has fallen to the ground from surrounding trees. Avoid storing food in garages and storage sheds unless the location is rat-proof. Keep trash cans closed and with tightly fitting lids. Repair any leaking faucets, sprinklers and/or piping. Do not allow standing water.
