Pest controllers inspect homes, businesses and other premises to identify infestations, assess how pests are entering and determine the extent of the problem. Common targets include rats and mice, insects such as ants, cockroaches, bedbugs, wasps and fleas, and birds or other wildlife where control is lawful. Some also investigate signs of pests in gardens, outbuildings, food storage areas and drainage systems. Services typically include setting traps or bait, applying suitable insecticides, removing nests where permitted, and advising on cleaning and safe disposal. Controllers may also seal gaps, fit proofing measures, recommend changes to waste storage and explain how to reduce the risk of pests returning. They can provide one-off visits or planned monitoring and treatment for homes, shops, offices, restaurants, warehouses and other commercial premises. Methods used depend on the pest, the location and any risks to people, pets or non-target wildlife.
