What are the signs of a bed bug infestation?

The signs of a bed bug infestation primarily revolve around the presence of physical evidence related to the bugs themselves and the consequences of their feeding habits. Itchy bites are often one of the most noticeable indicators, as many people experience allergic reactions to bed bug bites, which can result in red, itchy welts on the skin. Blood stains on sheets occur when bed bugs are inadvertently crushed after feeding, leaving a telltale mark. Additionally, dark spots, which are fecal matter left behind by the bugs, can often be found in areas where bed bugs hide, such as seams of mattresses, bed frames, or nearby furniture.

These signs collectively help identify a bed bug problem, distinguishing it from other pest infestations. In contrast, signs associated with other options may indicate different types of infestations; for example, chewed wires and furniture suggest the presence of rodents or some wood-destroying insects, while frequent stings and swelling could point towards biting insects like mosquitoes or fleas. Lastly, food droppings in the pantry typically relate to pests that infest stored food items, such as pantry moths or rodents, rather than bed bugs.
