  • Gnaw marks are knifeblade thin.
  • Droppings are 1/4 inch long. Cockroach droppings are about 1/8 to 1/4 inch long and have longitudinal ridges and squared-off ends. (Use a magnifier.)
  • Mouse tracks show 4 or 5 splayed toes.
  • Mice can make caches of seeds.

Control Methods

Habitat Modification

  • Sanitation & rodent proofing

Frightening Devices

None effective


Only effective in air-tight containers


  •  Anticoagulant and zinc phosphide baits


Mouse traps


Not practical

Other Methods

Many people mistakenly believe that cats will keep their property mouse free. Research and practical experience that cats are NOT an effective method of managing mouse populations. Additionally, house cats kill so many beneficial and protected species that their effect on ecosystems is too terrible to justify their use.
