Harrier Pest Control
Harrier Pest Control deal with cockroach infestations which are still remarkably common despite improved hugiene and housing standards over recent years.
Although there are several species of cockroach in the UK Harrier Pest Control largely find that there are two main pest species, the oriental cockroach (Blatta orientalis) is a large species of cockroach, measuring about 1 in (2.5 cm) in length at maturity, and the German cockroach (Blattella germanica), a smaller species of cockroach, measuring about 1.3 to 1.6 cm (0.51 to 0.63 in) long.
In order to thrive, cockroaches need a place to hide. They prefer warm places and a relatively high humidity if possible; they also need a source of food/liquid. Cockroaches are mainly nocturnal. Oriental cockroaches can be elusive in that a casual inspection of an infested dwelling during the day may show no signs of roach activity.
Signs of cockroaches are their oothecae, which are “egg cases” containing up to 16 individual eggs in the case of oriental cockroaches. These oothecae are dropped by females and hatch on their own in about two months. Oriental cockroaches can be harder to get rid of than other roaches as their oothecae can lay dormant for many months after being laid.
The German cockroach can be seen in the day occasionally, especially if the population is large or they have been disturbed. However, sightings are most commonly reported in the evening hours, as they are most active at night. This type of cockroach can emit an unpleasant odor when excited or frightened.
Professional cockroach control
The German cockroach in particular (also known as a “hood” in the US) is very successful at establishing an ecological niche in buildings, and is very hardy and resilient against attempts at pest control. This is because of the large number of nymphs produced from each egg case, the short period between birth and sexual maturity, and their ability to easily hide due to their small size. The mother also carries the egg case (ootheca) with her during the germination period, rather than depositing it like other species, a practice which would leave them vulnerable in a human habitat to zealous attempts to wipe them out. This cockroach is also smaller than many other species, so it can more easily hide and fit into very small cracks and crevices to evade humans.
That is also the main reason they can most effectively be controlled with bait in cracks and crevices near harborages. These pest control methods must kill 95% of the overall population to be effective in a property due to the fast reproductive cycles. Gel products, such as Advion and Max Force, are very effective against cockroaches.
The German cockroach, discounting the presence of pets, has few natural predators inside a human habitat. Its thigmotactic nature compounds the difficulty of pest control treatment. The immature cockroaches will live off excretions and moults from the adult cockroaches, so can remain hidden away from most surface treatments.
It is vital to get professional advice to eradicate cockroaches, your pest controller will have knowledge, not only of the of the most effective products to use, but also the best places and techniques for baiting.
More about cockroaches
The Oriental cockroach is dark brown to black in colour and has a glossy body. The female Oriental cockroach has a somewhat different appearance to the male, appearing to be wingless at casual glance but has two very short and useless wings just below her head. She has a wider body than the male. The male has long wings, which cover a majority of his body and are brown in colour, and has a more narrow body. The odd male is capable of very short flights, ranging about 2 to 3 meters. The optimum temperature for oriental cockroaches is between 20 °C (68 °F) to 29 °C (84 °F). Female oriental cockroaches have vestigial tegmina (reduced forewings) and males have longer tegmina.
The German cockroach (Blattella germanica) is a small species of cockroach, measuring about 1.3 to 1.6 cm (0.51 to 0.63 in) long; however, larger individuals have been recorded. It can be tan through brown to almost black, and has two dark parallel streaks running from the head to the base of the wings. Although it has wings, it is unable to sustain flight. Found throughout many human settlements. These insects are particularly associated with restaurants, food processing facilities, hotels, and nursing homes. In colder climates, they are found only near human habitats, since they are not very tolerant to cold. However, German cockroaches have been found as far north as Alert, Nunavut, and as far south as southern Patagonia.The German cockroach is originally from Africa. It is very closely related to the Asian cockroach, and to the casual observer they appear nearly identical and may be mistaken for each other.
