No Mice Here Mouse-proof my house
For landlords and property managers · Free

Mice in a rental? Seal it once.

A tenant sent you a note about mice? Here’s what a lasting fix includes, why poison costs you more, and a one-page printout to hand whoever does the work.

The standard.

  1. Walk all 10 spots, outside. Most entry points are on the outside of the building, so one sealing job can cover every unit. The 10 spots →
  2. Seal every gap about the width of a finger. If a finger fits, a mouse can get in.
  3. Use durable materials. 1/4-inch hardware cloth or exterior-grade metal, fastened and sealed in. Steel wool and foam on their own don’t keep mice out.
  4. Doors and the garage. Custom metal door sweeps with EPDM rubber. Garage door corner seals and a sound bottom seal.
  5. Pipes and AC lines. Sealed with metal or hardware cloth where each line goes into the wall.
  6. No poison and no bait stations. Take old stations away when the work is done.
  7. Clean up inside once, after sealing. Droppings and nests, the safe way: no sweeping. CDC clean-up steps
  8. Tell your tenant what was sealed. A short list or photos of each spot. Many tenants will check the work with our Check their fix list.

Why poison costs landlords more.

  • CallbacksPoison doesn’t close a single gap. New mice keep coming in the same way, and your tenant keeps calling.
  • OdorA mouse that dies out of reach can leave a smell that lingers. Tenants notice, and they call about that too.
  • Dead in the wallsPoisoned mice can die inside a wall, a ceiling or under a floor, where nobody can reach them. Getting one out can mean opening the wall and patching it.
  • Boxes left behindOld bait stations become shelters for pests, and they’re one more thing to manage at every unit.

Sealing is one repair that covers the whole building. Poison is a visit that comes back.

The one-pager.
