4 Definite Signs of Roach Activity in Your Home:
Cockroaches are nocturnal, meaning most of their activity happens overnight. Cockroaches prefer areas such as behind your fridge, sink, or other significant appliances because they enjoy dark, moist places throughout your home. With the ability to flatten their bodies to fit in small spaces, cockroaches can also reside within cracks in your walls. Learning to detect signs of cockroaches in your home is vital in protecting your property and family from disease and infestation. The faster you can spot a possible roach infestation, the sooner a pest management specialist can get inside and begin clearing your home so that you can live comfortably in a safe and protected environment. Here are 4 definite signs of roach activity in your home:

Physically Seeing A Roach- One of the most obvious signs you may have a roach problem is physically seeing one. As nocturnal insects, they are most easily spotted roaming your home at night. If you see one during the day, this could mean that the problem has been occurring for a while and immediate pest management is needed. If possible, roaches remain hidden during the day, but overcrowding and a lack of food sources can cause them to brave the daylight to survive. Of course, you will also find dead roaches in areas where they hide, since the infestation is just part of their natural life and death cycle. Dead roaches are not a sure sign the outbreak is over, but more likely that it is ongoing.
Roach Feces- Roaches eat everything from plant matter to people food, dead skin cells, garbage, and even feces, but their high metabolism turns this appetite into one of the most telltale signs of roaches: a considerable amount of roach droppings. Depending on what type of cockroach you are dealing with (e.g., German roach, brown-banded roach, etc.), as well as the size and level of infestation, the appearance of roach feces can vary to resemble anything from tiny specks of pepper to brown stains to coffee grounds to oval pellets. A large number of feces in a reasonably visible location can be a good indicator of a large roach infestation. Check behind the stove and refrigerator, as well as all sinks, pantries, cupboards, and other food storage areas in your home. If you spot a substantial amount of feces, you know the area is a high-traffic zone for roaches, so cut off nearby possible food and water sources. (very specific, hard time rewording)
Roach Egg Cases (Oothecae)- Roaches are very aggressive breeders, causing infestations to grow at a rapid rate. As opposed to single eggs, roaches produce oothecae- or an elliptical, brown casing that holds many eggs. Once the roach eggs hatch, the oothecae is left behind, leaving proof of evidence that roaches have taken a liking to your home. While it is possible to find oothecae with unhatched eggs still inside, it is uncommon as most species “glue” their oothecae to sheltered areas that are difficult for humans to find. While most species of common household roaches in the United States produce oothecae with only 10 to 20 eggs inside, the most common invader, the German roach, produces an ootheca with up to 50 eggs inside. This particularly protective mother carries the German roach ootheca around until the eggs are ready to hatch, making it even harder to spot or eliminate than with other species. Search for full or spent oothecae inside pantries, behind furniture, in between cracks in the wall, in books and other tight, protected areas.
Smelling Roaches- Finally, you can detect roach activity in your home by smell. Roaches leave a pungent, musty odor that gets worse as the infestation grows. This oily smell can come from several cockroaches, or just one German roach can produce this smell alone. There are also odors arising from dead roaches as oleic acid is produced during decomposition. Roach odors can linger in the air until the problem has been solved, and can even affect the taste of food in your home.
