1. LIFE CYCLE OF
COCKROACH

2. Cockroach
 The word cockroach comes from the
Spanish word "cucaracha" which means
"crazy bug".
 There are about 4,000 different species of
cockroaches in the world. About 50-60
species live in the United States.
 Cockroaches generally prefer
warm, humid, dark areas.
 The cockroach can live without its head
for an entire week.

3.  German cockroaches are very small. They
can squeeze through a crack that is about
1/16th of an inch wide.
 Cockroaches will eat almost anything
(omnivores): left-over human
food, paper, wood, leather, cigarette
butts, tooth paste, coffee
grinds, glue, soap, feces, fabric, shoes, pa
int, the glue on the back of
wallpaper, human hair, fingernails, etc.

5. Life Cycle of Cockroach
 The cockroach lifecycle actually has
three developmental stages. These
stages are known as the egg, the
nymph, and the adult stages.
 Some cockroaches choose to keep
their eggs safe internally whilst others
still carry the case around with them
until the eggs are ready to hatch.

6.  The cockroach lifecycle gets a bit more
exciting when the eggs hatch and the
young cockroaches are very small and
known as nymphs.
 The nymphs must go through several
stages of molting, where their body will be
quite soft and white. Nymphs are usually
white. Shortly after birth, they turn
brown, and their exoskeletons harden.

Nymph
 Each time the molting process is
completed the cockroach will get
bigger, change in color, and look more like
an adult cockroach.
 The nymph stage of the cockroach
lifecycle can take anywhere from a month
and a half to several years, depending on
the environment, the type of
cockroach, and the prevalence of
cockroach disease and parasites.

8.  In some species, this process takes
only a few weeks. In others, like the
oriental cockroach, it takes between
one and two years. The overall life
span of cockroaches differs as well --
some live only a few months while
others live for more than two years.

9.  The number of young that one roach
can bear also varies considerably. A
German cockroach and her young
can produce 300,000 more roaches
in one year. An American cockroach
and her young can produce a
comparatively small 800 new roaches
per year.
