How to exterminate a rat in the house? - briefly

Seal all possible entryways, then place snap or electronic traps with suitable bait (e.g., peanut butter) along walls and near suspected pathways, checking and resetting them daily until captures stop. Clean the area thoroughly and conduct periodic inspections to ensure the rodent does not return.

How to exterminate a rat in the house? - in detail

Eliminating a rat infestation inside a residence requires a systematic approach that combines inspection, exclusion, lethal control, and follow‑up monitoring.

Begin with a thorough inspection. Identify all signs of activity—droppings, gnaw marks, gnawed food containers, and nesting material. Trace pathways from the exterior to interior, focusing on utility openings, vent pipes, gaps around doors and windows, and cracks in foundations. Mark each entry point for later sealing.

Implement exclusion measures before applying lethal devices. Seal openings larger than ¼ inch with steel wool, metal flashing, or cement. Repair damaged screens, install door sweeps, and maintain a clean environment by storing food in sealed containers and removing standing water. Reducing attractants lowers the likelihood of reinfestation.

Select appropriate traps. Common options include:

  • Snap traps: positioned perpendicular to walls, baited with peanut butter or dried fruit, set on the active side of the wall.
  • Electronic traps: deliver a rapid high‑voltage shock, require battery maintenance, and provide a kill count.
  • Live‑capture traps: used only when relocation is permissible; must be checked frequently and released far from the property.

Place traps along identified runways, near droppings, and at concealed entry points. Use a minimum of three traps per active area, spacing them 2–3 feet apart. Replace baits daily to maintain potency.

If traps alone prove insufficient, apply rodenticides according to label instructions. Choose products formulated for indoor use, such as anticoagulant blocks or grains. Position bait stations in tamper‑resistant containers, out of reach of children and pets. Monitor stations regularly, replenishing as needed, and record removal of dead rodents.

After the last live rat is removed, conduct a secondary inspection. Verify that all entry points remain sealed, traps show no recent captures, and bait stations are empty. Maintain a schedule of monthly checks for at least three months to confirm the absence of new activity. Continuous sanitation and structural maintenance prevent future incursions.
