How can I eliminate mice in an apartment using tar? - briefly

Apply a thin coat of tar to baseboards, cracks, and behind appliances to form a sticky barrier that traps and deters rodents. Replace the tar periodically and seal all openings to prevent re‑infestation.

How can I eliminate mice in an apartment using tar? - in detail

Tar can serve as an effective rodent‑blocking material when applied correctly in a rental unit. The following procedure outlines preparation, application, and follow‑up actions.

Materials needed

  • Industrial‑grade tar or roofing tar in a container with a spout
  • Protective gloves, goggles, and a respirator mask
  • Disposable brush or small trowel
  • Steel wool or copper mesh
  • Sealant (silicone or acrylic)
  • Light‑weight cloth or paper towels for cleanup

Preparation

  1. Identify all potential entry points: gaps around pipes, vents, baseboards, and door frames. Use a flashlight to reveal cracks as small as ¼ inch.
  2. Clean each opening of dust and debris; a dry surface ensures adhesion.
  3. Wear protective equipment to avoid skin contact and inhalation of fumes.

Application

  • Warm the tar slightly (no more than 120 °F) to improve flow; do not overheat, which creates hazardous vapors.
  • Using the brush, apply a thin, continuous bead of tar over each opening. Ensure the bead fully covers the gap and extends at least ½ inch beyond the edges.
  • For larger cracks, first insert a plug of steel wool or copper mesh, then seal with tar to prevent mice from chewing through.
  • Allow the coating to cure for 15–30 minutes; the surface will harden and become impermeable.

Additional barriers

  • Apply a thin line of tar along the underside of baseboards where rodents commonly travel.
  • Seal gaps behind appliances and under sinks with a combination of mesh and tar.

Monitoring

  • Place snap traps or electronic monitors near treated areas for two weeks to verify activity has ceased.
  • Inspect the tar coating daily; reapply if cracks appear or if the material softens due to humidity.

Safety and disposal

  • Keep the workspace well‑ventilated; dispose of used brushes and contaminated cloths in sealed bags.
  • Store any remaining tar in a tightly sealed container away from heat sources.

By targeting entry points, using a durable tar seal, and confirming the absence of rodent signs, the infestation can be eliminated without resorting to poison or extensive fumigation.
