The answer to 'extermination infestation' is that a pest infestation can be caused by a variety of pests like rodents, insects, or other animals entering your home. Common symptoms include seeing the pests, finding droppings, damage to structures or food, and unpleasant odors. Solutions depend on the specific pest, but may include sealing entry points, removing food sources, using traps or baits, and in severe cases, calling a professional exterminator.
Many minor infestations can be handled with do-it-yourself methods, but for larger problems or difficult-to-eliminate pests, it's best to call in a licensed and experienced pest control professional. They have the specialized knowledge, equipment, and products to safely and effectively eliminate the infestation.
