Rats are dirty creatures that carry diseases and parasites. They leave droppings, get into food, and even eat through pieces of your home. Rats will continue to breed in a nest and the infestation will only get worse unless something is done quickly.

  1. 1

    Put on the goggles, gloves and surgical mask to locate the nesting area of the rats. Look around the attic for rat droppings or urine. Use the black light to see urine spots in the attic. Look for large amounts of droppings.

  2. 2

    Find all of the entry points throughout the inside and outside of the house. Rats mainly run along the edges, and rarely run out into the open. Look at the foundation of the house, holes in the soffits and drains. Seal off all of the holes with anything that they will not be able to eat through or push out. For example, use chicken wire to cover a hole and tack it into the siding with drawing pins.

  3. 3

    Bait all of the traps that are required for your home. Liver, cheese and peanut butter are all foods that rats will eat. Place the traps in what seem to be high traffic areas for them. Put them in the attic and close to the nesting point, especially. Do not over bait, as this will attract more rats to the house. Use twice as many traps as there are rats. For example, if there are 20 rats then use 40 traps.

  4. 4

    Check the traps every other day. Wear gloves, mask, and goggles whenever you are removing a dead rat and trap. Remove all dead rats and traps as soon as possible. Rats feed on each other, and if the dead rat is left too long then it could spread diseases or attract more rats. Dispose of the rat in a plastic bag. Seal the plastic bag and throw it away.

  5. 5

    Clean and disinfect all areas that the rats have laid droppings. Disinfect the nesting area if at all possible. Disease can still be spread by dead rats or leftover droppings. Clean all cabinets, and make sure to throw out any food that the rats may have got into.

  6. 6

    Place new traps after the infestation has been reduced or even eradicated. This will ensure that there are no future infestations. Keep all small crevices and holes blocked so that there is no rat problem in the future.

Tips and warnings

  • Don't poison rats living in the walls or they will ingest it and then die inside the walls.
