It is not uncommon for insects, rodents, and even birds to find refuge in a factory or warehouse setting. Insect pests include flies, beetles, and moths. These can be attracted to food storage areas or products made from natural materials like wool or cotton. Furthermore, pigeons and sparrows are often attracted to warehouses with open ceilings, which are ideal for attracting rodents like mice and rats. To prevent infestations in factories and warehouses, proper sanitation and pest control measures are essential.
