Cockroach Control

Common Name:German Cockroach

Scientific Name: Blatta germanica

Introduction: The German cockroach, (Blattella germanica) is a small species of cockroach, measuring about 1.3 cm (0.51 in) to 1.6 cm (0.63 in) long; however, they are known to get bigger. 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. The German cockroach is one of the most common and prominent household cockroaches in the world, and can be found throughout many human settlements. These insects are particularly fond of inhabiting 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. The German cockroach is originally from Asia, it is very closely related to the Asian cockroach, and to the casual observer they appear nearly identical and may be mistaken for the other. This cockroach can be seen in the day occasionally, especially if there is a large population or if 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.

Pest Control: The German cockroach 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 (called an 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.

Diet: The German cockroach is omnivorous and a scavenger. They particularly like starch, sugary foods, grease and meats. In certain situations where there is a shortage of foodstuffs, they may eat household items such as soap, glue and toothpaste or they may even turn cannibalistic, often chewing on the wings and legs of each other.

Control Of German Cockroach: German cockroaches are treated with insecticide, dust or gel. Approved insecticide's are used, in order to obtain elimination. Pestcatcher have to ensure that every infested location is treated. We Incorporat insect growth regulators (IGR) and monitoring into the services helping with long term control.

Common Name:Oriental Cockroach

Scientific Name: Blatta Orientalis

Introduction: The oriental cockroach (Blatta orientalis) is a large species of cockroach, measuring about 1 in (2.5 cm) in length at maturity. It 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.

Habitat: The oriental cockroach tends to travel somewhat more slowly than other species. They are often called "waterbugs" since they prefer dark, moist places. They can often be found around decaying organic matter, and in sewers, drains, damp basements, porches, and other damp locations. They can be found outside in bushes, under leaf groundcover, under mulch, and around other damp places outdoors.

Adaption: 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. 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. 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: 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. Although adults can be fairly easily killed by the application of residual insecticide, the insecticides can get washed away, and two months later females can hatch new nymphs.

Control: Oriental cockroaches are controlled by pestcatcher using insecticide or our Pest Shield Programme. We seal gaps in foundation walls, garages, basements, around gas, water lines and waste pipes. Ensure garage and front doors in homes and buildings are fitted properly.
