Cockroaches are obnoxious pests...
|
Y U C K ... Cockroaches are known
carriers of serious diseases, such as, salmonella, dysentery, gastroenteritis
and other stomach complaint organisms. They adulterate food and spread
pathogenic organisms with their faeces and defensive secretions.
Asthmatic reactions: Cockroaches must
moult regularly throughout their life-cycle. The discarded skin
becomes airborne and can cause severe asthmatic reactions, particularly
to children, the elderly and people with bronchial ailments.
The cockroach begins as an egg: The
female produces an egg sac which she carries or deposits in a safe
place. The young cockroach or "nymph" will undergo a series of
moults, shedding it's external skeleton, as it grows to adulthood.
The entire life cycle may extend to a few months depending on the
species and environmental factors, such as, access to food and
moisture, adequate shelter and warm temperatures.
Even the cleanest homes get'em: Cockroach
pests and their eggs are spread throughout the community in food
and other packaging. Although sanitation and hygiene are important
deterrants, even the cleanest homes become infested with cockroaches
due to minute deposits of grease, sugar and other food deposits
in difficult to get at places, such as, in drains, behind refrigerators
and dishwashers, inside cracks and crevices in kitchen cupboards.
Omnivorous by nature: Cockroaches
will eat almost any organic matter no matter how rancid. Once inside
the home, they will seek out food scraps, unsealed food containers,
sugar and grease deposits, pet food, rancid meat, glue and even
book bindings. YUCK...they eat each others faeces, to feed the
young "nymphs" and extract all nourishment from an organic
food source. If you see a clump of pepper-like specs in your kitchen
cupboards, it is likely cockroach faeces marking their courtship
and nearby nesting territory.
Nocturnal feeders: Cockroaches rest
during daylight hours in dark warm secure harborages in your home,
such as, in wall cavities, the subfloor, roof void, cracks and crevices
in the kitchen and bathroom, electrical appliances and foodstuffs.
They will emerge from these harborages in the still of the night.
Cockroaches have an array of acute sensory and survival instincts.
If you see cockroaches in your home during the day, you have a serious
problem.
Rapid breeding cycle: If left unchecked
a cockroach infestation can rapidly expand it's numbers in a few
weeks or months to become major risk to health and safety. |

Professional Pest Control: Cockroaches
|
IGR cockroach baits: Modern science
has the answer. A cockroach food bait that has a delayed lethal
effect ... ensuring enough time for the bait to be transferred
to other cockroaches by each others faeces.
The IGR bait is an insect growth regulator that stops the ability
of the cockroach to replace it's skin - made of "chitin". These IGR's
are of ultra low toxicity to people. Applied as small blobs in cockroach
habitat areas away from human contact, the gel-bait is highly attractive
to cockroaches and provides effective control, usually for many months.
Permethrin dust: In some cases, we recommend
the use of a synthetic pyrethroid (permethrin) dust inside roof voids
and under floors. The permethrin dust is modelled on the natural
extract of pyrethrum flower and is less toxic than common salt but
deadly for cockroaches. |

What the Home Owner can do
|
Inspestion: first, inspect the entire
kitchen area, under sinks, refrigerator, dishwasher, stove, microwave
oven, other cooking appliances, bathroom cabinets, draws, basement
and subfloor crawlspace (if any) for likely high activity and harborage
areas. Look for cockroaches, alive or dead, their faeces and egg
sacs.
Identification: place "sticky" glue
traps in any likely high activity areas. At night sneak into the
kitchen, turn on the lights and observe any cockroach activity.
Observe where they scurry to. Place your sticky traps near these
areas to collect and identify the species and the source of infestation.
Food, shelter and water - we all need
it, so do cockroaches. Make your home unfit for cockroaches, where
possible, take away their food, water and restrict shelter and
access points into the kitchen and they will almost certainly move
somewhere else.
Starve them out - keep all food in
sealed containers. Particularly at night, do not leave food scraps
exposed in the kitchen or waste storage areas. Thoroughly clean
all benches and food preperation areas, particularly between counters
and appliances. Regularly vacuum accessible likely harbourage and
high acivity areas, carpets, drapes, furniture, kitchen and bathroom
cupboards in order to remove cockroach eggs and food deposits.
Cockroaches need water and will thrive
in damp subfloor crawl space areas, near leaking taps, etc. Ensure
adequate drainage and ventilation. Regularly check and fix any
plumbing problems, broken roof tiles, etc that may allow or cause
moisture agress to potential cockroach harborage areas. Wipe kitchen
sink of moisture before retiring or going out at night. Turn off
leaking taps.
Reduce shelter and access points: seal
all cracks and crevices in bathroom, pantry and kitchen cupboards.
Store all cardboard boxes and the like above ground level. Cockroaches
do not like drafty exposed areas, nor bright lights. A good reason
why some restaurants keep lights on at night around their dumpster
waste bins. |

Cockroach Species Identification
|
Correct identification is essential: There
are several cockroach pest species that infest domestic and commercial
premises. The identification of each species is neccessary to best
determine likely harborage areas and an effective pest control
program. |
| German
cockroach --- Blatella germanica |
Identification: The body of an adult
german cockroach is about 1/2 inch in length. Biege to light brown
in color, with two dark stripes on back of head..
World best traveller? The German cockroach
is the most widely transported insect pest in the world. Infestations
even occur in Alaska, in larger installations with central heating
or around machinery that produces heat.
In warmer climates, it is commonly found in homes, apartments, restaurants,
food processing plants, supermarkets and warehouses. Their eggs arrive
in food containers, cartons, fridges, stoves and other appliances
or materials brought into a building.
Habitat: German cockroaches are unable
to survive in locations away from humans or human activity. German
cockroach infestations usually occur in bathrooms and kitchens. They
like to hide-out during the day in tight secure places.
Their daytime harborage areas are usually near a food and moisture
source, such as, inside wall cavities, behind baseboards, cracks
and crevices in pantry, kitchen and bathroom cupboards, and under
electrical, heating and cooking appliances.
Rapid breeding cycle: The German cockroach
is the most prolific breeder among all cockroaches. The female German
cockroach lives up to 6 months. She carries an egg capsule containing
30 to 40 eggs. Development from egg to adult can occur in 45 days,
during which they moult 6 times.
The German cockroach will breed rapidly throughout the year, but
favours a humid environment of around 80F or warmer. An small initial
infestation can become a major problem in a few months. |
| American
cockroach --- Periplaneta americana |
Identification: The largest of the
cockroach pest species, the body of an adult American cockroach
or "water bug" is 1.5 to 2 inches in length. Color: reddish brown,
with a yellowish band behind the head.
Habitat: Preferred daytime habitat locations
include the subfloor, basement, in sewers and other warm, dark, moist
locations. They avoid cold areas but will thrive outdoors in temperatures
above 80F. Indoors they often congregate around hot water pipes,
fridge motors, boilers and other heating appliances. The American
cockroach will feed on a wide variety of plant and animal material.
Rapid breeding cycle: The female life
span up to 1.5 years; incubation period of eggs 6 to 8 weeks; in
ideal conditions they quickly reach plague proportions. |
| Oriental
cockroach --- Blatta orientalis |
Identification: The body of an adult
oriental cockroach is about 1 inch in length. Dark brown to black
in color.
Habitat: Most often found in dark
basements or cellars, but can also climb garbage shutes, sewer
and water pipes to the upper floors in highrise buildings. Oriental
cockroaches prefer to feed on starchy foods.
Rapid breeding cycle: The female lives
up to 2 years; deposits up to 18 egg-sacs in lifetime; each eggsac
contains 16 eggs; incubation period is 1 to 2 months; development
period is 12 months, undegoing 7 moults.
An infestation will rapidly expand in ideal conditions, particularly
during the warm summer months with temperatures regularly above 80F. |
