The answer to 'why is my rat infestation' is that rats have likely infested your home due to a combination of factors, including easy access to food, water, and shelter. Rats are highly adaptable and can thrive in both urban and rural environments, making them a common pest problem for many homeowners.
Some of the most common causes of a rat infestation include improperly stored food, leaky pipes or water sources, and gaps or cracks in the home's exterior that allow rats to enter. Rats can also be attracted to cluttered or unkempt areas, as these provide ideal nesting spots. Signs of a rat infestation may include droppings, gnaw marks, and unusual noises, such as scurrying in the walls or attic.
