Everything You Need To Know About American Cockroaches In St. Louis

December 03, 2021 - Cockroaches

The American cockroach, also known as the palmetto bug, is actually the largest pest in the United States. It is a grayish-brown cockroach that can grow up to three inches long. They are nocturnal because they are typically active late at night or early in the morning.

How To Tell If You Have An American Cockroach Infestation

American cockroaches will be seen during the day if there's a large population and food source present or after a heavy rainstorm because roaches can't swim, so they drown and surface with the first heavy shower.

While they are most active during the hours of darkness, you need to be on the lookout for signs of an infestation:

  • A strong musty odor
  • Their fecal droppings or spotted black and brown shells of dead roaches
  • Large numbers of roaches
  • Cockroach egg cases

American Cockroaches Are Dangerous

American cockroaches are a big health risk to humans. The saliva and parts of the cockroach's body may contain allergens that can trigger asthmatic symptoms in people having asthma or breathing problems.

The feces of this type of roach carry bacteria that may cause food poisoning and other organisms that cause the following:

  • Plague
  • Dysentery
  • Leprosy
  • Cholera
  • Viral diseases
  • Typhoid fever

Factors That Attract American Cockroaches & How To Reduce Them

There are a few basic things that the American cockroach needs. These are shelter, food, moisture, warmth, and water. This cockroach prefers the warmth of our homes where they feed, mate, and lay eggs, but they also can thrive outside under debris, logs, leaf litter. Moist areas inside that appeal to American cockroaches include the kitchen and bathroom.

Shelter is another reason why American cockroaches find their way into your home or around your property. They are commonly found within cracks, crevices, and walls of residential homes as they tend to hide in hidden spaces that people don’t normally notice because they do not see it or because they are dark colored.

American cockroaches are highly adaptive, and that's why it's necessary to take steps to prevent them from invading St. Louis homes:

  • Seal cracks and crevices in preferred hiding places. For example, in kitchen cabinets, under the sink, in sinks, and around pipes.
  • Address and repair leaks.
  • Check your home for evidence of infestation before you purchase new furniture or appliances. American cockroaches do not generally bite people, but they will leave an unpleasant odor behind on any surface they inhabit.
  • Keep kitchen surfaces clean of food and spills, and don't leave dirty dishes overnight. 
  • Regularly vacuum the home. 
  • Remove hiding places by keeping your home free of clutter.

You can also use traps and baits that will attract and kill the roach. For example, kitchen and pantry areas typically have more cockroaches than other rooms in your home, but they can also be found in the laundry room, basement, attics, garages, and crawlspaces.

The American cockroach reproduces at a rapid rate and can populate throughout your home if not treated properly.
