Cockroaches in Cincinnati

People always get disgusted when they see cockroaches and what to do when they show up. So what are some facts about these pests and why do they show up and what to do about it?

Cockroaches are a year-round pest but are most likely to show up inside in the colder months because it’s a time of hibernation, and inside is the right environment. Because the presence can be year-round, the constant monitoring and treatments need to be done on a continual basis. Chemical resistance can develop so understand the risks.

Any treatments must consider the structure being treated; whether it be residential, industrial or commercial.

There are 4,000 species of cockroaches in the world, and many can live 2 – 4 years. Yet, only 1 percent of all cockroach species invade homes and businesses and can be a danger to humans and pets. They reproduce year-round so checking is required, even though reproduction numbers go down during colder weather. Cockroaches can come into your home with groceries, open doors, or with other deliveries of packaged or unpackaged materials.

There have been comments that cockroaches are called water bugs. This isn’t true. Many say that because it doesn’t sound as bad. Water bugs can be more solitary and be found around liquid water sources. Cockroaches are not solitary and congregate together in small or large numbers.

So what are some of the differences in cockroaches we may see in North America?

The most common cockroaches in the Midwest are Oriental cockroaches, German cockroaches and American cockroaches.

Oriental cockroaches – mostly dark brown, larger (3/4” long) and heavier and like to live mostly in lower level areas like basements and crawl spaces.

German cockroaches – mostly lighter brown, smaller (1/2”) and like to live mostly upper levels of structures like kitchens, baths, garages and around restaurants

American cockroaches – Can be smaller or larger depending on species, and live mostly in sewers and sewer pipes so keep an eye on basement drains and drain covers.

A scary factor is about cockroaches is how fast they can multiply. Different species multiply at different rates, but all reproduce at astounding rates.

Oriental cockroach females produce an average of eight capsules, each containing 16 eggs that hatch in about 60 days under room temperature conditions. Nymphs molt from seven to ten times; nymphal stages usually take 24 to 130 weeks to complete. The life span of an adult female is 5 to 26 weeks with approximately 200 offspring

The German cockroach has three developmental stages: egg, nymph, and adult. Females produce a light brown, purse-shaped egg capsule that is less than 1/4 inch long and contains two rows of eggs. Each capsule contains up to 35-45 eggs, and adult females usually produce from four to eight egg capsules during their lifetime. At room temperature, one capsule is produced about every 6 weeks. Egg capsules are carried, protruding from the abdomen, until hatching time when they are deposited into crevices and other sheltered locations. The life span of the adult female varies from 20 to 30 weeks. In one year over 10,000 descendants can be produced, assuming two generations per year.

Responsible treatment must happen to stop the multiplication.

So what can be done to rid cockroach presence or infestation? First, it has to be done by a professional. There needs to be a determination of the kind of cockroach, the location of where they are, what to attraction is, how many of them are there, and the correct treatment options due to human occupation, pet presence, or special health considerations of certain employees.

Another factor of cockroaches is the side effects like allergies and diseases. Cockroaches produce proteins on their bodies that can be allergenic. There are possibly over 10 million people who may be allergic to cockroaches. Since cockroaches are in constant contact with filth, waste, and decaying materials, they can bring that into dwellings and businesses. There can be severe adverse reactions to what they drag into any environment.

There are large infestations that are troubling. And large means that there are hundreds and hundreds of cockroaches present. Hooper Pest Control has had to begin by first going in with an industrial vacuum cleaner with a HEPA filter and suck these huge quantities of roaches up first. These large infestations can require relocation of families. And infestations aren’t in just dwellings that are not kept up. Even neat-a-holics can have these nocturnal invaders, and be undetected for some time.

Topical treatments many times miss the where majority of roaches are. 75% of the time German Roaches are in cracks and crevices, and deep voids behind cabinets and appliances, Roaches prefer to rest in tight opening, 25% of the time venturing out looking for food.   Many pest control companies miss the cracks and crevices where females hide. Repeat treatments are sometimes required because if some egg capsules hatch you can have anywhere from 35 to 1,000 new nymphs.  Treatment with Baits, Pheromone traps, Dusts, and sometimes materials are necessary to flush the roaches out of the cracks and crevices so they can be vacuumed with a heptavac and removed from the premises. This will remove not only the roaches, but the egg capsules, containing thousands of nymphs.
