Cockroaches : are among one the filthiest germ spreading carriers
There are over 3,500 identified species of cockroaches, they are very good at adapting to the environment. Cockroaches are “Nocturnal”, they typically prefer warm, humid climate, especially near food sources such as kitchens, toilets and bathrooms. They are usually scattered around the cracks in the walls or floor, in the drains and sewers.
Cockroaches are relatively primitive, having only three stages in their life cycle: egg, nymph and adult. The female deposits its eggs in groups surrounded by a leathery, bean-shaped egg case or capsule called an ootheca. Oothecae are very distinctive and can frequently be used to determine the species.
Some species carry the ootheca for several weeks attached to the back end of the body until getting close to hatching time. Different species deposit their eggs differently, some of the species can be Asexual reproduction, some species deposit the eggs in the ground, in the wall or furniture. The number of the eggs in the ootheca also varies depending on the species, normally there are 16 to 18 eggs in one ootheca, some may deposit many groups, some deposit 4 – 6 groups, and some can deposit up to 90 groups. Depending on the species, temperature and humidity, the eggs take different period to hatch, the eggs hatch faster with warmer temperature.
The young cockroaches, or nymphs, are wingless, they are white on hatching. After 3 – 4 weeks, they grow in stages by repeatedly shedding the cuticle or skin until they are fully grown. The adults may or may not possess wings, the species with wings, small wings grow out of the second section and third section of the thorax then grow bigger when fully grown. Once the cockroaches are fully grown, they start to reproduce, and after depositing all the eggs, they live for several more days.เต็มวัย บางชนิดก็ไม่มีปีกเลย เมื่อเจริญ เป็นตัวเต็มวัยจะมีการผสมพันธ ุ์และการวางไข่เกิดขึ้น หลังจากวางไข่หมดก็จะมีอายุต่อไปได้อีกหลายวัน

Cockroaches move freely from buildings to buildings or from drains, gardens, sewers and toilets to human habitations when they crawl over food or dishes, they leave germs and filth behind which cause dangerous infectious diseases such as diphtheria, typhoid, hepatitis and gastroenteritis.
Damages & Problems : Cockroach
1. Baiting system – cockroach bait is used in the arear where infected
2. Powder System – powder chemical for preventing cuticle shedding is used to prevent the
growth of the cockroaches
3. Residue Chemical Spraying - chemical agent that effectively stops the nervous system of the
Standard Services : Cockroach
A thorough survey especially hidden area where there is food to identify the problem and to establish the appropriate treatments required. The treatment can be chemical powder where spraying is ineffective.
Placing cockroach bait, gel type or granular type, are also effective for the area that spraying or chemical powder are not suitable. Inspection and follow up are performed periodically.
Client’s cooperation is required upon providing the service. The treatments must be done thoroughly in all the hiding places and in every corner, inaccessible and locked up areas could be where the high concentration of the cockroach population, and that could cause ineffectiveness of the treatments.
Advices and information on sanitation or proper maintenance of the premises are good measure to reduce the cockroach’s outbreak.
