Detecting signs of rats in your home is crucial for early intervention. You may find small, dark, pellet-like droppings along rat pathways or in secluded areas. Scratching, scurrying, or squeaking noises, often coming from walls, ceilings, or crawlspaces in the middle of the night could indicate rodent presence. Look for chewed wires, furniture, or structural materials, as rats constantly gnaw to control their teeth growth. You can’t miss a pungent, ammonia-like odor from rat urine and feces. Also, dark, greasy marks along the walls or baseboards where rats rub their bodies indicate a frequent pathway. Look around your attic — disturbed insulation, shredded paper, boxes or other materials indicate rats are nesting. If you notice any of these signs, it is essential to address the rat infestation promptly to prevent health hazards and structural damage.
