American Cockroach (Periplaneta americana):
The American cockroach, also known as the Palmetto Bug or Waterbug,
is the largest species of common cockroach, and often considered a pest.
American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water.
They prefer warm temperatures around 29 °C (84 °F) and do not tolerate cold temperatures.
In residential areas, these cockroaches live in basements and sewers, and may move outdoors into yards during warm weather.
These cockroaches are common in basements, crawl spaces, cracks and crevices of porches, foundations, and walkways adjacent to buildings.
The American cockroach is a scavenger that feeds on decaying organic matter and a variety of other foods.
It is particularly fond of fermenting foods.
German Cockroach (Blattella germanica):
The German cockroach, Croton bug or Steam fly is a small species of cockroach, measuring about 1.3 cm (0.51 in) to 1.6 cm (0.63 in) long.
It can be tan through brown to almost black, and has two dark parallel streaks running from the head to the base of the wings.
Although it has wings, it is unable to sustain flight.
The German cockroach is one of the most common and prominent household cockroaches in the world, and can be found throughout many human settlements.
These insects are particularly fond of inhabiting restaurants, food processing facilities, hotels, and nursing homes.
In colder climates, they are found only near human habitats, since they are not very tolerant to cold.
This cockroach can be seen in the day occasionally, especially if there is a large population or if they have been disturbed.
However, sightings are most commonly reported in the evening hours as they are most active at night.
