German Cockroach
The German cockroach is very common. The adults are comparatively
small, about 1.5 cm long, tan in colour and often occur in large
numbers, in kitchen areas, supermarkets and restaurants. Because
they are the smallest of the cockroach species usually found in
homes, people may think these smaller cockroaches are the young
of the larger American cockroach.

This cockroach is very small and can often infest inside
buildings. Unlike German cockroach that infests kitchens and food
handling areas,
the Brownbanded cockroach will infest all areas of a building. This
cockroach prefers warm condition and can often be found around warm
appliances like radios and televisions. Because they prefer the warmer
conditions they are not found to infest apartments and homes that
have air conditioners as much as those that don’t. They have
wings and can fly. They are often pale brown in colour with two brown
banded across their wings. They prefer to eat starchy foods, which
is why they can often be found in offices and other place that store
paper. Because of the fact that they may infest entire building it
can make them difficult to control. Stewarts can organize a maintenance
program for your property to treat any species of cockroach.
