The answer to 'what do bed bugs look like' is that bed bugs are small, flat, oval-shaped insects that are reddish-brown in color. They are about the size of an apple seed, around 4-5 mm long. Bed bugs have six legs, no wings, and their bodies are covered in short, golden-colored hairs. When they feed on blood, their bodies swell and become more elongated and red in color.
Bed bugs are often found in cracks and crevices around the bed, such as in the seams of the mattress, box spring, or bed frame. They can also be found in other furniture, behind baseboards, and in other tight spaces where they can hide during the day and come out to feed at night.
