Well stored wood & lumber

    Rat survival and prosperity requires three basic environmental conditions:

  • Abundant food
  • Available source of water
  • Access to suitable harborage

    Good environmental management practices, supplemented by the wise use of rodenticides and trapping are the most effective approaches to rat control.

Harvest fruits as soon as they ripen. Pick up all fallen fruit.

Never leave uneaten pet food outside overnight.

Algerian ivy, oleander, bougainvillea, and other thickly matted plants should be thinned and trimmed well away from roofs, walls, fences, utility poles, and trees.

Store wood and lumber piles on racks at least 18 inches above the ground and 12 inches away from the walls; clean up debris piles.

Repair leaky faucets and eliminate any other unnecessary standing water.
