The answer to a rat problem is to first identify the signs of a rat infestation, such as droppings, gnaw marks, or noises in the walls or attic. Common causes include easy access to food sources, nesting spots, and gaps in the home's exterior. Rats can spread diseases, contaminate food, and cause property damage, so it's important to address the problem promptly.
For minor infestations, homeowners can try DIY solutions like sealing entry points, removing food sources, and using traps or repellents. However, for more severe or persistent problems, it's best to call in a professional pest control technician. They have the expertise and equipment to properly identify the extent of the infestation, implement effective control methods, and prevent future issues.
