American cockroach

Periplaneta americana

The American cockroach (Periplaneta americana), also known as a bug or water bug, or erroneously identified as a palmetto (see Florida woodland cockroach for differences), is the largest species of common cockroach, and is often considered a pest. None of the Periplaneta species are endemic to the Americas; Although the name P. americana was introduced to the United States from Africa as early as 1625, it is now common in tropical climates due to human activity's expansion of the insect's living range, the contribution of international shipping to the port of the world, and the Including the southern United States, the Canary Islands, southern Spain, Greece, Taiwan, and Cape Town and Durban, South Africa.


Properties

An adult American cockroach grows to an average of about 4 cm (1.6 in) in length and about 7 mm (0.28 in) in height. They are reddish-brown in color and have a yellow margin on the body area behind the head. Immature cockroaches are similar to adults, except that they lack wings.

The insect can move quickly, often darting out of view when someone enters a room, and it can slip through small openings and under doors, no matter how large it is. It is considered one of the fastest running insects.

In an experiment conducted at the University of California, Berkeley in 1991, Periplaneta americana recorded a speed of 5.4 kilometers per hour (3.4 mph), or about 50 longitudinal bodies per second, which is comparable to a human running at 330 kilometers per hour (210 mph). /s).

It has a pair of large compound eyes, each with more than 2,000 separate lenses, and is a very active nocturnal insect that avoids light.


risks to humans

Cockroaches can carry disease-causing bacteria such as Salmonella on their legs, and later put them on food and cause food poisoning. Household dust containing excrement and body parts of cockroaches can trigger allergies and asthma in some individuals.


Home of the American cockroach

American cockroaches usually live in moist areas, but they can survive in dry areas if they have access to water. It prefers warm temperatures around 29°C (84°F) and does not tolerate cold temperatures. In residential areas, these cockroaches live in basements and sewers, and may move outdoors into courtyards when the weather is warm. These cockroaches are usually found in basements, crawl spaces, cracks and openings in porches, foundations, and walkways adjacent to buildings.

The American cockroach is a scavenging insect that feeds on decaying organic matter and a variety of other foods. He especially loves fermented foods.


life cycle

The female produces an egg sac called an ovary, which protrudes from the tip of the abdomen. After about two days, the egg sacs are placed on a surface in a safe place. The egg sacs are about 0.9 cm (0.35 in) long, brown, bag-shaped. Immature cockroaches emerge from their egg sacs after about 6 to 8 weeks, and take 6 to 12 months to reach maturity. Adult cockroaches can live for up to a year, during which time the females produce an average of up to 150 baby cockroaches.


live in homes

Because of their large size and slow growth, there is little presence of these insects indoors. However, during certain times of the year, these cockroaches can move from the outside into the home. In cold weather these cockroaches may move indoors, looking for higher temperatures and food. Cockroaches can enter the home through sewer connections, under doors, around sewers, through vents, or other openings in the foundations. Cockroach numbers can be controlled using insecticides.
