Start by identifying the pest and looking for what is attracting it, such as food scraps, standing water, damp areas or entry gaps. Clean thoroughly, store food in sealed containers, repair leaks and block small openings before using chemicals. If you use a store-bought product, follow the label exactly, keep children and pets away, and never mix pesticides or use outdoor products indoors. For termites, wasps, rodents, extensive infestations or pests affecting health, consider a licensed pest controller who can recommend a suitable treatment.
