Asian Cockroach: They have been known to carry germs and can spread diseases to humans. Asian cockroaches are capable flyers, also live primarily outdoors, typically located in shaded, moist areas. While they are more likely to infest outdoor areas, they do sometimes enter homes. Asian cockroaches are most active at dusk and fly long distances toward sources of light. You may see an Asian cockroach attracted to your television screen or perched near lamps and other sources of illumination.
Brown Banded Cockroach: The brown-banded cockroach tends to inhabit areas that are less humid and much warmer, with a temperature greater than 80 degrees Fahrenheit. In structures, these insects are most frequently found congregating on ceilings, in attics and in or around appliance motors, for example. Active primarily at night, the brown-banded cockroach may be seen wandering in search of food during the day. They have a preference for materials with a higher starch content, such as book bindings, wallpaper glue and stamps.
German Cockroach: German cockroaches are most commonly found indoors, with a preference for the warmer and more humid areas of a structure. In homes, these insects will typically be found in kitchens and bathrooms, but can move to other areas of a home if food and moisture are available. In most cases, German cockroaches are introduced into a structure or residence when bags, boxes or cardboard containers are brought into the home. They may even be brought in with used appliances. In multiunit apartment buildings, German cockroaches can easily move between units, using the shared plumbing and pipes as a highway. They are scavengers, capable of feeding on most any food source available, including toothpaste, soap and the bindings of books. These pests are known for their ability to capitalize on the availability of even the smallest amounts of food by feeding on crumbs missed during cleaning or feeding on the dirty dishes left in the sink overnight.
Smoky Brown Cockroach: Around homes and structures, the smokybrown cockroach can be found in tree holes and cavities, beneath mulch beds and ground cover, and around soffits and eaves, or areas where moisture problems may exist. The smokybrown cockroach can easily penetrate buildings through openings or gaps beneath siding, through attic or soffit vents, openings around utility and plumbing penetrations, and through open windows or doors. These opportunistic feeders will utilize any food that may be available, including human food scraps, dead insects, fecal matter and even plant materials
