The answer to 'signs of extermination' is that common signs of a pest infestation that may require extermination include seeing the pests themselves, finding droppings or nests, and noticing damage to your home or belongings. Some key signs include seeing rodents or insects, finding chewed food packages or wires, spotting nests or egg casings, and noticing strange odors or noises. If you notice these signs, it's important to act quickly to prevent the problem from getting worse.
In many cases, homeowners can try DIY pest control methods like setting traps, using baits or sprays, or sealing entry points. However, for more severe or complex infestations, it's best to call in a professional pest control technician. They have the expertise and equipment to properly identify the pests, determine the extent of the problem, and implement the most effective treatment plan to fully eliminate the infestation.
