They prefer to hide in warm, elevated areas near the ceiling, behind wall decorations, pictures, loose wallpaper, in shower stalls, underneath chairs and tables, in closets, beneath or inside upholstered furniture, and in electrical appliances such as TV sets, stereos, radios and toasters. Roaches can foul food, damage wallpaper and books, eat glue from furniture and produce an unpleasant odor. Some homeowners are allergic to roaches, and the pests can contaminate food with certain bacterial diseases that result in food poisoning, dysentery or diarrhea. Cockroaches can cause childhood asthma. Identification Most cockroaches have a flattened oval shape, spiny legs, and grow long, filamentous antennae.
Males are capable of flight.
Nymphs and females are broad when viewed from above, while the male is slender. The male's wings cover the abdomen, whereas the female's wings are short, exposing the abdomen. These bands may appear irregular or broken, but are usually quite apparent on the nymphs and females. Immature stages are smaller, have undeveloped wings and resemble adults. Cycle Brownbanded cockroach females deposit egg cases in clusters inside furniture, undersides of tables, draperies, wall decorations, shelving and ceilings.
