“The most common of all cockroach species worldwide is the German Cockroach pictured here”.
There is fossil evidence which indicates that cockroaches have been on earth for over 300 million years. The German cockroach did not originate in Germany as their name would suggest but instead scientists believe they originated in Southeast Asia. They are adaptable and have successfully adjusted to living with humans. They have survived every disaster in history, and they will survive many more. Although there are over 3,500 species of cockroach’s world wide in Canada, we commonly deal with four species. The German Cockroach, the Brown Banded cockroach, the American cockroach, and the Oriental cockroach. The common species that we deal with in Alberta and Saskatchewan is “The German Cockroach” (Blattella germanica).
“Since they have been on earth for millions of years these nasty bugs know how to adapt and are survivors!”
The German Cockroach has complete metamorphous- egg, nymph, and adult stage. Their life cycle spans approximately 100 days. The egg capsule is purse shaped and contains 30-40 eggs per egg case. Egg capsules are carried by the female protruding from the abdomen until it is time to hatch and will be deposited in a sheltered location. They are prolific breeders and in one year over 10,000 descendants can be produced, assuming two generations per year. They are the biggest breeders of all the cockroach families. This makes them the most pervasive roach species on the planet.
