Known to be nocturnal, cockroaches tend to hide away in crevices during the day. They may also be found lurking near drains and sinks, among other places that provide the ideal conditions to survive. In cases of a large influx of this pest, often, a foul, almond-like scent can be smelt.
As for appearance, the German Cockroach is relatively small, with an average length of 1.6cm. This species has a light brown body and two dark lines starting from the cockroach’s head and ending at the bottom of the wings (it cannot fly, however). Oriental cockroaches However are 17-30mm in length. Dark brown to almost black in colour, shiny and have a flat body, the female has smaller wing buds than the males, the males wing buds almost reaching the end of the abdomen. These cockroaches have long flexible antennae. They cannot fly nor can it climb smooth surfaces like the German Cockroach but is very fast running.
Although, in warmer climates, this prominent type of cockroaches is likely to infest restaurants and nursing homes, among other properties, in colder areas of the globe, they tend to stay close to human residences.
A cockroach’s life is broken up into three stages. They start off as an egg and, once they hatch, they begin life as a nymph before developing into an adult insect.
Despite this, their transformation from egg to adult is relatively quick, taking roughly 100 days in most cases. In saying this, external variations can make a difference to their development, such as temperature and whether they are receiving adequate nutrition.
Throughout their lives, these cockroaches will breed incessantly, resulting in overlaps when it comes to life stages. Providing ideal living conditions are in place, cockroach numbers, when it comes to an infestation, can reach enormous heights. Typically speaking, cockroach populations will consist of roughly 20% adults and the remaining 80% will be developing nymphs.
Adults will usually survive for around three to six months, and they will moult anywhere from five to seven times during their lifespan.
Cockroach’s diet will comprise of anything from scraps on the floor to pet food, and the species may even result to feasting on the bindings of books as well.
Cockroaches can affect a property and its inhabitants in different ways, but arguably what’s most alarming is that they can carry harmful diseases and organisms.
These germs can be passed on through direct contact, either with the pest or through their droppings. This pest can also contaminate food, making cockroach control in big cities like Manchester crucial.
Cockroach control should only ever be carried out by professionals, as it can be complicated, and the pests are notoriously difficult to get rid of thanks to their breeding process and hiding places.
To begin with, the extent of the infestation should be monitored, and nightly assessments should be carried out, as this is when the pest is likely to be most active. For the latter to be successful, torches with red filters are most effective.
During treatment, all food and water sources should be cut off to direct the infestation towards insecticides.
As a number of egg cases are hidden away in crevices, insecticides need to be strategically placed and maintained throughout the life stages of this pest. Ideally, this method should be used routinely until all cases have hatched, and to control the infestation, frequent treatments are required. Treatments can be residual insecticidal spray, gel baits or traps. To achieve complete control of cockroaches, at least 3 treatments are required.
