What do bed bugs look like?
When it comes to identifying adult bed bugs, picture a reddish-brown flattened oval about the size of an apple seed. Wingless, these bugs do become a darker red after taking in a blood meal. Newly hatched bed bugs are much smaller than the adults, are lighter colored, and are no bigger than a pinhead. Bed bug eggs are white to opaque and are so tiny that they are almost impossible to see with the human eye.
