Cockroaches

The facts

That allowing any type of insect or rodent within your premises or home will obviously be a nuisance and in some cases serious illness, loss of business and in extreme circumstances, legal and civil prosecution. There are 2 main types of Cockroach one been German Cockroach the other is Oriental or Common Cockroach. The German Cockroach is 12 to 15mm, mid brown, with a yellow brown thorax having two dark brown stripes. long antennae. wings full length in male but 2/3 length in the female. The female carries the ootheca and deposits it, nymphs hatch after one to two days. Four to eight ootheca are produced each containing 30 to 40 eggs. There are six to seven nymphal stages to adulthood. The longevity of the insect is 128 days for male and 153 for the female. The Common Cockroach is 17 to 30mm, dark brown to black, very shiny and very flattened, the female has very reduced wing buds and the male wings are longer to almost the end of the abdomen. Colonies are often established in drains or services but sometimes in cladding and dead spaces inside processing equipment. Ootheca produced five to ten per female each containing 16 to 18 eggs, incubation takes 48 to 80 days at 20c to 25c preferred temperature. Nymphal stages seven to ten to adult, life span 60 to 250 days depending on temperature.

Where do Cockroaches live?

Cockroaches live in a wide range of environments around the world. Pest species of cockroaches adapt readily to a variety of environments, but prefer warm conditions found within buildings, dustbin areas, boiler houses, inside tray wash plants, inside switch boxes, motor housings, panels inside machines, fridge motors and conduits etc.

Why keep Cockroaches under control?

Cockroaches are one of the most commonly noted household pest insects. They feed on human and pet food, and can leave an offensive odour. They can also passively transport microbes on their body surfaces including those that are potentially dangerous to humans, particularly in environments such as hospitals. Cockroaches have been shown to be linked with allergic reactions in humans. One of the proteins that triggers allergic reactions has been identified as tropomyosin. These allergens have also been found to be linked with asthma.

Prevention & Control

The use of crawling insect monitors or cockroach traps will help on this initial inspection. Their sitting will give an indication to the size of the problem. Treat wall and floor junctions plus cracks and crevices especially pipe chases with an insecticide to create a barrier. Emergence of immature stages will be controlled on hatching depending on the integrity of the barrier left. Cleaning, washing down and high temperatures will affect the life of the selected pesticide. Voids and known harbourages must be reached with the insecticide formulation with injection equipment. Baits can be used in inaccessible areas but treatment with a wettable powder and emulsion concentrate preparations are more effective with dust in ductings. Night inspections must be planned-in in a serious infestation and these should be carried out from midnight to 3am.
