What is the description of the insect that is 1/4" long, reddish brown, wingless, oval-shaped and flat?

The insect described as being 1/4" long, reddish brown, wingless, oval-shaped, and flat aligns closely with the characteristics of a bed bug. Bed bugs are known for their flat bodies, which allow them to easily hide in small crevices and seams. Their reddish-brown coloration and oval shape are also defining features.

In contrast, fleas are typically smaller than bed bugs, usually around 1/8" long, and have a more elongated body shape. Scabies is not an insect but rather a mite, and ticks, although similar in size, have a more rounded body shape and are often larger when engorged with blood.

This identification of bed bugs is crucial, especially for pest control technicians who need to recognize these organisms for effective treatments and client education.
