  1. 1

    Remove all trash, wood and weeds from under your trailer and around the exterior area of your trailer. Mice inhabit areas heavily populated by trash, boards and weeds. Burn all trash and unwanted wood material and mow the area around your trailer to remove grass, weeds or dense vegetation. Lay a tarp under your trailer to prevent grass and weeds from growing.

  2. 2

    Bait the snap traps with peanut butter and place them in diverse areas under your trailer. The University of Georgia College of Agricultural and Environmental Sciences recommends setting the bait treadle of the snap trap at a right angle to a wall for maximum success.

  3. 3

    Check the snap traps multiple times per day. Rats are most active at night, so check the traps at that time.

  4. 4

    Remove the snap traps, containing dead mice, from under your trailer and dispose of them properly. Place the snap trap, along with the deceased rodent, into a secure plastic bag and either bury or burn the bag.

  5. 5

    Set new snap traps under your trailer. The University of Georgia College of Agricultural and Environmental Sciences recommends leaving the traps in place for a few weeks to ensure you catch and remove all mice.

  6. 6

    Locate and seal all small holes or openings in your trailer's underpinning with caulk or steel mesh wire. According to the National Center for Healthy Housing, mice can get through holes as small as one-quarter inch.

  7. 7

    Spray a Tabasco sauce and water mix around your trailer to repel mice from re-entering the area under your trailer. Mice don't like the taste or scent of Tabasco sauce. Pour one-quarter mix of Tabasco sauce and three-quarters mix of water into a spray bottle and spray the outside area around your trailer evenly with the solution. Reapply on a regular basis, especially after a rainy day, for lasting success.

Tips and warnings

  • Always wear sanitary gloves when handling snap traps containing dead mice. Mice carry and transmit a wide array of harmful diseases.
  • Place multiple snap traps inside your trailer, as mice can easily travel into your home if they are already located under your trailer.
  • Don't pile wood against your trailer as it attracts mice. Always pile wood away from your home and at least a foot off the ground to prevent mice from inhabiting the wood pile.
  • You may have to call in a professional exterminator if your mice infestation is severe.
  • Avoid using poison traps as such traps will not kill mice immediately, but allow them to venture into your home or yard and die at a later date. Animals that consume poisoned rats can become poisoned and die as a result.
