The German cockroach (Blattella germanica) is a small species of cockroach, typically about 1.1 to 1.6 cm (0.43 to 0.63 in) long. Of the few species of cockroaches that are domestic pests, it probably is the most widely troublesome example.
The German cockroach occurs widely in human buildings but is particularly associated with restaurants, food processing facilities, hotels, and institutional establishments such as nursing homes. German cockroaches are omnivorous scavengers. They are attracted particularly to meats, starches, sugars, and fatty foods.
The German cockroach reproduces faster than any other residential cockroach, growing from egg to reproductive adult in roughly 50 – 60 days.
The German cockroach is very successful at establishing an ecological niche in buildings and is resilient in the face of many pest-control measures. Reasons include:
- lack of natural predators in a human habitat
- prolific reproduction
- short reproductive cycle
- the ability to hide in very small refuges
- sexual maturity attained within several weeks, and
- adaptation and resistance to some chemical pesticides
To be effective, control measures must be comprehensive, sustained, and systematic; survival of just a few eggs is quite enough to regenerate a nearly exterminated pest population within a few generations, and recolonization from surrounding populations often is very rapid, too.
Another problem in controlling German cockroaches is the nature of their population behavior.
Though they are not social and practice no organized maternal care, females carry oothecae of 18-50 eggs (average about 32) during incubation until just before hatching, instead of dropping them as most other species of cockroaches do. This protects the eggs from certain classes of predation.
Without proper pest control, your property can become an ideal breeding ground for cockroaches.
