Symptoms
Bed bug bites are the most common symptom of an infestation. The bites are small, red, and itchy and are often found in a line or cluster on exposed skin. Some people may not show any symptoms at all, while others may have an allergic reaction to the bites.
Other symptoms of a bed bug infestation include finding small, reddish-brown bugs or their shed skins in the seams of mattresses or furniture, a musty odor in the room, and blood spots on sheets or mattresses from squashed bugs.
Causes
Bed bugs are commonly found in places where people sleep or sit for long periods of time, such as beds, sofas, and chairs. They can also be found in other places such as airports, movie theaters, and public transportation. Bed bugs can also be brought into the home by bringing in used furniture, clothing or bags from infested areas, or by travelling to infested areas.
Bed bugs are able to survive for long periods of time without feeding, so they can be difficult to eliminate once they have infested an area. They can also reproduce rapidly, which makes infestations difficult to control.
