Rats cannot live without food, water or shelter.  You can get rid of rat problems by following these simple steps!

 

Step One: Rodent proof your home and storage buildings!

  • Check the outside of your house for holes or gaps the size of a quarter or larger
  • Repair all openings using rodent proof materials:1/4 inch 18-22 gauge wire hardware cloth
  • Install metal weather stripping under doors to remove gaps

Step Two: Remove food sources from your property!

  • Keep garbage cans covered at all times
  • Pick fruit, nuts and vegetables as they ripen, and throw away or compost fallen fruit on the ground
  • Feed pets during daylight hours only, and remove uneaten food right away
  • Avoid storing food in garages and storage sheds at night unless in rat-proof covered metal containers

Step Three: INSIDE your home use traps, not poison bait!

  • Poisoned rats may die inside walls or attics, creating odors and attracting flies
  • Use snap traps when rats are inside your home
  • Place traps at entry points, or where you have seen rat droppings
  • Use CAUTION when placing traps around children or pets
  • Bait the traps with peanut butter or the food the rats have been eating
  • Tie down traps to prevent injured rats from dragging the traps away and dying inside your walls
  • Check traps at least twice a week

Step Four: OUTSIDE your home use poison bait!

  • Keep bait away from children and pets
  • Rodent proof your home BEFORE using poison bait
  • Always read the label and follow directions when using poisons
  • Multi-dose, anti-coagulant poisons are the most effective, and the rat may need to feed on the bait for several days for it to work
  • Place poison bait in an enclosed bait station, where rats and their droppings have been found
  • Make sure bait is in a protected area, such as under woodpiles or thick vegetation where rats may be hiding
  • Check bait stations twice a week and add bait when necessary
  • Place dead rats in sealed plastic bags and put them in the trash
  • Move to step five when rats stop eating bait

Step Five: Get rid of rat habitat!

  • Remove all trash and debris
  • Stack woodpiles, lumber and household items at least 18 inches above the ground, 12 inches away from fences and walls
  • Trim trees, bushes and vines to at least 4 feet away from the roof
  • Remove heavy vegetation such as ivy, bougainvillea and pyracantha away from buildings and fences
  • Thin vegetation to allow daylight in and remove rat hiding places
