The answer to 'what do bed bugs look like' is that bed bugs are small, oval-shaped insects that are usually brown or reddish-brown in color. They are about the size of an apple seed, measuring 4-5 millimeters in length. Bed bugs have flat bodies and six legs, and they feed on human blood, typically at night when people are sleeping.
Bed bugs are often found in cracks and crevices around the bed, such as in the mattress seams, box springs, and bed frames. They may also be found in other areas of the home, like behind baseboards, in furniture, and in clutter. Identifying bed bugs can be challenging, as they are good at hiding and can be difficult to see with the naked eye.
