How To Identify A Cockroach Infestation.
Cockroaches are the most frequently present household pest. In North America, both American and German cockroaches are present. American cockroaches are sometimes referred to as “palmetto bugs.” Cockroaches are sometimes mistakenly referred to as “water bugs,” which is a distinct species from roaches.
Appearance - American cockroaches are the larger cockroach, growing up to 3 inches long, with a yellow stripe behind the head. German cockroaches tend to be about a half an inch long (as small as the tip of your thumb) with a tan, shiny-rounded back. German cockroaches have two black stripes on their body just behind their heads.
Behavior - Before seeing a cockroach first hand, you may notice what looks like coffee grounds or sprinkled pepper in areas prone to cockroaches. If you haven’t made coffee or seasoned some food, these may be cockroach droppings, which normally a sure sign of a cockroach infestation. Roaches in large groups let off a chemical that encourages them to stay together. This smell is often described as a musty, stale, or moldy scent. Cockroaches tend to move and feed in the dark. Once you see a cockroach during the day, it is likely that the cockroach problem is severe.
