The answer to 'rat invasion' is that rats can become a serious problem in homes, causing damage and potentially spreading diseases. Common causes include easy access to food sources, nesting sites, and poor sanitation. Symptoms include droppings, gnaw marks, and noises in walls or attics.
For minor infestations, homeowners can try DIY solutions like sealing entry points, removing food sources, and using traps or repellents. However, for larger or recurring problems, it's best to call a professional pest control service. Experienced technicians can properly identify the issue, implement effective treatments, and provide ongoing prevention strategies.
