Start where the smell is strongest. Keep children and pets away.
Flies near a window or grille may help narrow the search. They do not prove a rat is present.
Inspect behind the fridge with a torch. Get help before moving heavy appliances.
Use existing inspection panels. Arrange safe wall or ceiling access; never cut blindly.
Wear gloves and a mask. Disinfect, double-bag and follow local disposal guidance. Never sweep droppings dry.
Odour may fade in one to three weeks or longer. Charcoal or baking soda offers limited help.
Avoid poison. Seal entry gaps, secure food and monitor for fresh signs.
