Microscopic dust mites are everywhere in the home - in our beds, clothing, furniture, book shelves and stuffed animals. For people with allergies or asthma, dust mites are a problem. Bedbugs are pests that thrive around human dwellings. They live on human blood for survival. They have received their name from its close association with human bedding. They generally hide in the seam of the mattress and in the cracks of the bed and feed on the bed's occupants at night. If the population of bed bugs is very large it spreads in the entire house. The bedbugs may also hide in other pieces of furniture and cracks and crevices in the walls. They spread mainly by baggage and clothing of travellers and visitors, bedding material and furniture.
