Cockroaches

Pest Control Methods

Cockroaches are obnoxious pests

  • Cockroaches carry diseases (salmonella, dysentery, gastroenteritis, to name a few) and spread pathogenic organisms with their faeces and secretions.
  • Cockroaches must moult several times as they grow from young nymph to adult; their discarded skin becomes airborne and can cause severe asthmatic reactions.
  • Cockroaches and their eggs are spread throughout the community in food and other packaging
  • Cockroaches will eat almost any organic matter no matter how rancid – once inside your home they will seek out food scraps, unsealed food containers, pet food etc.
  • Cockroaches rest during daylight hours in dark warm secure harborages (eg. in wall cavities and the subfloor) and come out at night. If you see cockroaches in your home during the day, you have a serious problem.
  • If left unchecked a cockroach infestation can rapidly expand to become major risk to health and safety.

Professional pest control for cockroaches

Fumapest Termite & Pest Control uses the latest cockroach eradication technologies – IGR cockroach baits, designed as a palatable food source for cockroaches. IGR cockroach baits have a delayed lethal effect of a few days, which is enough time to be spread to the other cockroaches. The male cockroach is the primary food gatherer and will spread the bait throughout the entire cockroach population, with guaranteed effective results.

The modern cockroaches baits are formulated as a gel of ultra low hazard to people, dogs, cats and other mammals. They are applied as small blobs in kitchen cupboards and 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 is applied inside wall cavities, roof voids and subfloor areas. With specialist equipment we can put the insecticidal dust into such hard to get at areas where cockroaches congregate and breed. The Permethrin dust is modelled on the natural extract of pyrethrum plant and is less toxic than common salt to human and mammals.

A liquid insecticidal spray may be used in as interior skirting boards, sheds, garages, fences, garbage refuse areas, around top of drains and immediate external perimeter of buildings.

What you can do when you find cockroaches

  • Inspection: 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.
  • 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.
  • 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 preparation 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.
  • 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.
  • 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.

Cockroach species identification

Several cockroach pest species occur in a variety of domestic and commercial premises – identification of each species and knowledge of each species habits are essential to best determine likely harborage areas and an effective pest control program.

German cockroach – Blatella germanica

cockroach1The body of an adult German cockroach is about 1/2 inch in length, beige to light brown in color, with two dark stripes on back of head. The German cockroach is the most widely transported insect pest in the world. These cockroaches are commonly found in homes, apartments, restaurants, food processing plants, supermarkets and warehouses.

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.

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.

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. Obviously, a small initial German cockroach infestation can become a major problem within a few months.

American cockroach – Periplaneta americana

This is the largest of the cockroach pest species – the body of an adult American cockroach cockroach2or “water bug” is 1.5 to 2 inches in length. The American cockroach is reddish brown, with a yellowish band behind the head.

Preferred daytime habitat locations of the American cockroach include the subfloor, basement, in sewers and other warm, dark, moist locations. 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.

The female life span up to 1.5 years; incubation period of eggs 6 to 8 weeks; in ideal conditions they can quickly reach plague proportions.

Oriental cockroach – Blatta orientalis

cockroach3The body of an adult oriental cockroach is about 1 inch in length, dark brown to black in colour. They are 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.

The female lives up to 2 years; deposits up to 18 eggsacs in lifetime; each eggsac contains 16 eggs; incubation period is 1 to 2 months; development period is 12 months, undergoing 7 moults. Infestation will rapidly expand in ideal conditions, particularly during summer.

 

Australian cockroach – Periplanta australasiae

The Australian cockroach is reddish brown and looks similar to American cockroach but is cockroach4smaller at 35mm in body length. The Australian cockroach has yellow strips on the outer edge of the front wings. Despite its name it occurs world-wide. The Australian cockroach prefers a vegetarian diet, it is known to eat holes in clothing and even book covers.

They are prevalent in greenhouses and near large heating apparatus, air-conditioners or other equipment emitting heat constantly. They are opportunistic fliers and will infest anywhere adequate heat, humidity and food supply is available. Prime areas of interest are often pet food bowls and food waste storage areas.

The female lives up to 6 months; incubation period of eggs 40 days. An infestation can rapidly expand in ideal conditions. Chronic household infestations usually emanate from the roof void, attic or sub-floor areas of the building.
