Cockroaches thrive wherever food, warmth, and water meet. Learn to identify the three species most common to Southwest Missouri—and how to help keep them out of kitchens, restaurants, and workplaces.

• German Cockroach (Blattella germanica) – Light brown with two dark stripes behind the head; prolific breeder found in kitchens and bathrooms.

• American Cockroach (Periplaneta americana) – Reddish-brown “water bug” up to 2″; often associated with sewers, boiler rooms, and commercial kitchens.

• Brownbanded Cockroach (Supella longipalpa) – Tan with two light bands across wings; hides in warm, dry upper cabinets and electronics.

Egg cases (oothecae) can contain 14–48 eggs depending on species. Nymphs molt 6–13 times before adulthood. Under favorable conditions, German cockroaches may complete a generation in as little as 36 days, which is why infestations can build rapidly without intervention.

• Can potentially spread bacteria such as E. coli and Salmonella by contacting food and food-preparation surfaces.

• Asthma and allergy symptoms may be worsened by shed skins, droppings, and other roach allergens.

• Odor issues in heavy infestations caused by aggregation pheromones and roach secretions.

• Vacuum crumbs beneath and behind appliances on a regular schedule.

• Fix drippy faucets and leaks—roaches can survive long periods with minimal food but rely on moisture.

• Store dry goods in airtight containers and discard excess cardboard that can harbor egg cases.

• Seal gaps around pipes and wall penetrations with silicone, foam, or escutcheon plates.

• Run kitchen and bathroom exhaust fans to help reduce humidity.

• Small pepper-like droppings in cabinet corners or along baseboards.

• Oval brown egg cases attached to pantry walls, shelving, or appliance motors.

• Noticeable, musty “roachy” odor in enclosed cupboards or storage areas.

• Nighttime sightings when lights are switched on in kitchens or bathrooms.

Yes. Roach allergens from droppings, cast skins, and saliva can contribute to asthma and allergy flare-ups, particularly in children and those with existing respiratory conditions.
