Roaches are not native in Ohio, but they are “naturalized” in the sense that they have been transported or traveled from nearby areas in search of food, and now they are established in the wild. These are the most adaptable creatures and can live anywhere while feeding on anything.
The most common cockroaches in Ohio are:
1. American Cockroaches
Description: American cockroaches are typically oval, reddish-brown with a yellowish figure 8 pattern on the back end of the head; they have six legs. Adult cockroaches range between 1 ¼ to 2 ⅛ in length and have an antenna, which helps them in smelling food.
Habitat: They prefer habitats where food and water supply is readily available, and they are generally found outdoors. Despite the name, the American cockroach is found all over the world. When they do not go indoors, these can be found crawling inside dark spaces. But they’re generally found in places like woodpiles, dead logs, and hollow trees.
Life Cycle: The American cockroach is the most giant and most common roach infesting the house. A female roach lays about 16 eggs at once and produces about six to fourteen ootheca during her complete lifespan, with an average incubation period of 44 days. That makes up to 224 offspring at a time. They go through ten to thirteen instars before reaching adulthood and take around 600 days on an average. Males can live up to a year, whereas adult females can live for more than 700 days.
2. German Cockroaches
Description: They are Light brown to tan and usually have a darker color in the early stages of development, which lighten to a faint brown in later stages. They have long, comprehensive, and flat bodies, with six legs and two long antennae protruding from the head. They also have two dark longitudinal lines on the shield behind their head. These are among species of cockroach that do not fly, despite having wings, which helps in catching or tracking their progress through the house.
Habitat: They cannot survive in locations away from humans or human activity. This pest is therefore spotted in hotels, residential areas, farm produce markets, catering establishments, swimming baths, hospitals, shops, stores, restaurants, food manufactures’, nurseries, crèches, and grain stores. The majority of the roach population is found in the kitchen or bathrooms.
Life Cycle: The German cockroach breeds throughout the year indoors, but favors a humid environment and an average temperature of approximately 80°F. A life cycle takes about three months in its process. They produce more eggs per capsule than other pest cockroach species, and their young nymphs complete their growth in a shorter period and take an average of 103 days. Female German cockroaches carry their egg capsules until they are ready to hatch. The quantity of eggs in a capsule is usually 30-40, and the average incubation period is about 28 days. They progress through six to seven nymphal stages in 60 days for males and 65 days for the female roach who may live for more than 200 days.
Weather in Ohio
Ohio is a comparatively more relaxed place, and the highest temperature in summers rises to 90°F (32.2°C) at the peak of July, which implies that roaches mostly away outdoors and the infestations are not too much here.
Risks Associated with Cockroaches
- While foraging, the nymphs and adults can contaminate and infect foodstuffs, which are later consumed by humans.
- They spread bacteria and parasites that may be living inside them, which results in various bacterial infections.
- They spread allergic reactions and many other health risks ranging from food poisoning to asthma.
- They secrete a foul-smelling discharge from their body, which also contaminates food.
