SIZE: 1/2 – 5/8 inch (13-16mm)
COLOR: Light brown to tan
with two dark parallel bands running from behind their head to their wings.
DESCRIPTION: The German
cockroach is one of the most commonly encountered species infesting Toronto.
Readily infesting houses, apartments, restaurants and other institutions
throughout Toronto and the GTA.
HABITAT: They are active mostly
at night, and hide in dark crevices during the day. If German cockroaches
are seen during the day, the population may be high and the available harborage
is full, or food and moisture are in short supply resulting in daytime foraging.
German cockroaches prefer to stay close to moisture and food and are generally
found in the kitchens and bathrooms.
LIFE CYCLE: German cockroaches
are highly successful due to the high rate of reproduction. The female
carries the egg capsule protruding from the rear of her abdomen until the
eggs are ready to hatch. Each egg capsule will contain 30-48 nymphs (young).
It takes 28 days from the initial formation of the egg capsule until it
hatches. Formation of the next egg capsule usually begins within 2 weeks.
Nymphs require as little as 40 days to become a mature adult. Adults German
cockroaches can live up to one year.
TYPE OF DAMAGE: In addition
to being a nuisance by readily infesting our food, German cockroaches have
been implicated in outbreaks of illness and may cause allergic reactions
in some people.
CONTROL: There are two equally
effective methods for eliminating cockroach infestations. The use of Maxforce
gel or other commercial roach bait will completely eliminate roach infestation.
This product is a stomach poison and is consumed by the roaches, it is highly
effective however may take 4-6 weeks to achieve complete control. Benefits
of the bait treatment include: reduced risk of spreading infestation in
multi-unit dwellings, no preparation required, safe or infants and pets,
no need to vacate during treatment. The alternative method is to spray using
residual insecticides. A spray treatment will provide very quick results
and usually only take about a week to completely eliminate infestations.
Preparation for this treatment will include emptying all kitchen cupboards
and bathroom vanities, and vacating the premises for a minimum of 4 hours.
