Although Cockroaches are useful outdoors . Although cockroaches are useful outdoors, where they help recycle plant and animal wastes, they are not welcome indoors. Research clearly indicates that roaches can carry disease-causing organisms from sewers, garbage cans, or bathrooms to kitchen counters and human food.
Cockroaches can also trigger allergic reactions in some people.
Except for size and markings, all cockroaches have a similar appearance. These insects are dark in color, oval-shaped, and have long antennae. Roaches are mainly active at night and generally remain hidden during the day in cracks and crevices near their source of food. Use nontoxic sticky traps to locate roach habitat. Roaches like to travel by touching the edges of objects.
