Cockroaches
·
One of the oldest insects - fossil remains date
back 200 million years.
·
Crawl around on six legs, have wings and two
antennae.
·
Like dark, damp places with a plentiful food
supply; hide during the day in warm, dark
places, such as under sinks, behind dishwashers,
stoves and refrigerators, and inside cupboards.
·
Feed on a variety of foods, especially starchy
and sugary materials, including book bindings,
photographic film, linens, leather goods and
numerous food items; usually forage at night.
·
Can survive a month or more without food, but
less than two weeks without water.
·
Have an acrid odor that may permeate items with
which they come in contact.
·
Can transmit bacteria and organisms responsible
for diseases in humans including food poisoning,
cholera, dysentery, salmonellosis and strep.
·
A study by the National Institute of Allergy and
Infectious Diseases and a report in the New
England Journal of Medicine indicate that
exposure to cockroach allergens is a major
health concern for asthmatic children.
·
Under optimum conditions, cockroaches can
produce two million offspring in one year, with
an average breeding season resulting in 350,000
offspring.
·
Found around the world. Two species are
prevalent in the United States, the American
cockroach and the German cockroach.
·
The American cockroach has reddish-brown wings
and light markings on its thorax and reaches
lengths of up to 1.5 inches.
·
The German cockroach is between one-half and
five-eighths inches long and is light brown with
two dark stripes down its back.
