The answer to 'extermination infestation' is that common causes include rodents, insects like cockroaches or ants, and other pests that can infest a home. Symptoms may include seeing the pests, finding droppings or nests, and damage to food, property, or structures. Solutions depend on the type of pest, but can include sealing entry points, removing food sources, and using traps, baits, or sprays to eliminate the infestation.
In many cases, a DIY approach using over-the-counter products may be effective for minor infestations. However, for larger or more complex infestations, it's best to call in a professional pest control technician who can properly identify the problem and use the right treatments to get rid of the pests for good.
