Indoor insects can be identified by examining the color, texture and consistency of their droppings. For example, indoor termites leave piles of tiny, encapsulated droppings that resemble sawdust or salt and pepper. Termite droppings in the home typically indicate an infestation and should be examined by a pest control specialist.
Another example are cockroach droppings, which are typically brown in color and resemble coffee grounds. Cockroaches also excrete brown liquid feces that emit a foul odor, and if found often indicates that multiple cockroaches have gathered in one area. These marks are often found behind picture frames and along the tops of cabinet doors, and due to potential allergic reactions, illness and asthma attacks, it is important for homeowners who discover cockroach feces to consult with a pest control specialist as soon as possible to ensure proper extermination.
Carpenter ant droppings consist of chewed wood and insect parts. The droppings are typically the same color as the wood in the home or dwelling and are soft and crumbly in consistency. Carpenter ant droppings typically appear in piles in close proximity to small openings in wooden structures. The openings are referred to as windows and are often found in basements and porches. Carpenter ant infestations can lead to severe structural damage, so it is important to contact an exterminator as soon as possible if droppings are discovered.
