The statement that adults are about the size and shape of an apple seed is accurate because adult bed bugs typically measure about 4 to 5 mm in length and have a flattened, oval shape that is reminiscent of an apple seed. This distinct shape and size assist in their identification and indicate their potential to hide in small crevices, which is a key characteristic of their behavior.

Bed bugs are generally visible to the naked eye, however, they do not resemble cockroaches; this distinction helps prevent misidentification. While bed bugs can be found more frequently in areas with higher human activity and perhaps less hygienic conditions, they are not exclusively found only in dirty environments; they can inhabit clean homes, hotels, and other areas where people sleep. Furthermore, bed bugs are not larger than most household pests, as they are smaller when compared to common pests like cockroaches and ants.
