Basic Rodent Proofing

Repairs for rodent proofing are usually very simple and inexpensive if you catch invasions early. Periodic inspection of your property should be conducted to insure that proper rodent proofing is still intact.

 

Rodent Proofing for the Home

  1. Replace vent covers that have holes or are starting to rust. All mesh must be ¼ in or smaller. Make sure all attic vents are covered with ¼ in or smaller screen.
  2. Fill holes or cracks with concrete or cover cracks with sheet metal or wire mesh. Rats will quickly chew through spray foam or wood.
  3. Replace damaged weather stripping under doors and garage doors. You should not be able to fit your thumb underneath.
  4. Replace damaged window screens.
  5. If your roofline has roof pitch junctions or gables, make sure there are no holes or cracks. Seal these areas with sheet metal or hardware cloth. Replace all missing or damaged roof tiles.
  6. Place rat guards or metal cones on drain pipes to prevent rats from climbing them

1/4 inch hardware cloth, cement fill, and sheet metal are all excellent materials to use for sealing up gaps and holes.

 

Rodent Proofing for the Garden

  1. Trim back all tree branches away from the house. Ideally no branch should be closer than 2 feet to your roof line. Remove over hanging branches.
  2. Remove all ivy or climbing vines from the side of your home. These can hide damage and provide an easily climbable surface.
  3. Trim all bushes away from the side of the house and create space between plants to remove cover for rodents.
  4. Pick up all dropped fruit from trees every day and protect backyard vegetables by placing them in raised beds or covering with a protective mesh.
  5. Place all garbage or compost in rat-proof containers.
  6. Clean up after bird feeders or do not feed wildlife. The rats benefit more than the birds.

 

Rodent Proofing for Mobile Homes

  1. Close all holes in skirting larger than 1/4 inch.
  2. Older mobile homes with vinyl or metal skirting can be repaired by first making sure the bottom track at ground level is in good shape. Having the track set on cement is preferred because it can be secured with concrete anchors. A hard surface under the track will also help stop animals attempting to dig under the skirting. With a good track in place, new skirting can be installed.
  3. Newer mobile homes use wood or Hardie Board for the skirting around the base of the home. They tend to be sturdier than the metal panels of older homes. Animals may dig under the skirting but you can use wire mesh or pavers to fill the gap of the compromised area.
  4. Use tape or other materials to seal openings in under-belly wrap, including openings where pipes enter the home.
