Cockroaches
What do they look like?
The two main species of cockroach in Britain are the Oriental
cockroach which is dark brown in colour and about 30mm long, and
the German cockroach which is light yellowish brown, and about 12mm
long. The bodies of both species are divided into three sections.
They have long antennae protruding from the head.
Where do they live?
Generally found indoors, such as in cellars, basements,
kitchens, bakeries, and heating ducts etc. The Oriental cockroach
can survive outdoors in Britain during the summer months.
What do they eat?
All Cockroaches will feed on a wide range of substances,
particularly refuse and human food. Cockroaches can survive for
several months without food but will not live for more than a few
weeks without water.
Pest status
Cockroaches will often remain hidden during the day using
cracks and crevices as harbourage. This means that in most cases
they will not be visible during the hours of daylight. Most species
can climb with ease, especially the German cockroach which can
climb smooth vertical surfaces.
Control
Hygiene
Before carrying out a treatment against cockroaches, a
thorough cleansing of the area to be treated should take place,
paying particular attention to removing food sources and hiding
places.
Sticky Traps
The use of sticky traps is not recommended for controlling
cockroaches, and should only be used for monitoring the extent of
the infestation.
Insecticidal Control
Carrying out a successful treatment against cockroaches will
depend on what insecticides are chosen, and how thorough the
application is. Many of the insects and their egg cases are hidden
in cracks and crevices, so particular attention should be paid to
these areas when applying insecticides. To control an infestation,
the insecticide used should last until the egg cases have hatched.
This may mean further applications may be necessary.
Insecticide Baits
Baits can give continuous control of cockroaches over an
extended period.
