Cockroaches
Cockroaches have existed for
millions of years and there are many species around the world. They
are very successful as they eat almost anything, breed rapidly and
tolerate a wide range of conditions.
Description and life
cycle
German cockroach - This species grows up to 15 mm and is
light golden brown in colour. It prefers warm, humid conditions and
climbs even smooth surfaces easily. The young (or nymphs) look very
similar to the adults as they grow. Females lay egg cases that
contain up to 30 eggs. These hatch and the nymphs feed and grow by
moulting their skins. This takes 5 months or more and the adults
then live for up to 6 months.
Oriental cockroach - This species is larger, up to
25 mm long and dark brown in colour. It is found in cooler, less
humid areas like basements and drains. It can climb rough but not
smooth surfaces. Nymphs are similar to adults as they grow. Females
lay egg cases that contain up to 16 eggs. These hatch and the
nymphs grow by moulting but this takes from 10 months to 2 years.
The adults live for up to 9 months.
Problems they cause
Cockroaches spread disease by contaminating our food and coming
into contact with work surfaces and utensils used for food
preparation.
They eat our food but spoil much more with their droppings, cast
skins and dead bodies. They breed rapidly and can easily be spread
from one place to another.
Treatment
Our Officers will provide the professional help
needed. They will inspect the property to determine the extent of
the problem. Treatment will be carried out, normally using a bait
that cockroaches find very attractive.
