Pest Summary

Termites

TermitesFeatures

  • Body is flat and soft;
  • Possess very strong jawbones;
  • Color vary by species from white, yellow, brown to dark brown;
  • All termites eat cellulose in its various forms as plant fibre.

Termites are almost living in the humid environments, particularly in the subtropical and tropical regions. They can destroy wood furniture, house furnishings, bone dry wood, wood door, plant and farm. Termites are difficult to detect because of cryptic nature and are a destructive force when left unchecked. If termites are found, do not try to eliminate the termite nest by yourself. It would make the termites spread widely and more difficult to control.

Our professional technicians investigate circumstance, termite species and erosion and take the most suitable solution by drilling and injecting all termite target areas to prevent recurrence and infestation.

Rodents

RodentsRat and mouse are rodents. The common species of commensal rodent in Hong Kong are:

  1. Rattus norvegicus (Rn), sewer rat; also known as norway rat.
  2. Rattus rattus (R2), house rat; also known as roof rat.
  3. Mus musculus (Mm), mouse.

Features

  • social animal and nocturnal
  • good climber, especially for Rattus rattus.
  • good jumper and swimmer
  • range of movement: 30-50m for rats, 5-10 m for mice
  • Rats are omnivorous, eating a wide variety of foods.
  • rat takes 15-30 gm food and consumes about 30 gm water daily,
  • mouse takes only 3 gm of food and small amount of water everyday.
  • 5-8 litters per year, 5-14 per litter

Rodents are carriers of viral, rickettsial and bacterial diseases. The causative agents could enter our body by four different ways:

  • through the ectoparasites of rat like fleas, ticks and mites
  • by food or water contaminated by rodent excreta
  • through direct contact with rodent excreta
  • by rat bite

Our professional technicians use poisonous bait or traps to eliminate harbourages for rodents and confine the rodent activity area for enhancing the rodent disinfestations work.

Mosquitoes

CulicidaeFeatures

  • slender and long mouth parts, scaly wings and complete head for larvae
  • a pair of spiracles on the dorsal part of the 8th abdominal segment of the larvae

Among the more than 1600 species found around the World, 72 species have been found locally. 11 species of these locally found mosquitoes are Anopheles. The common local mosquito-borne disease vectors are:

  • Anopheles jeyporiensis
  • Anopheles minimus
  • Aedes togoi
  • Aedes albopictus
  • Culex quinquefasciatus
  • Culex tritaeniorhynchus

Mosquitoes raise a public health concern. Mosquitoes are estimated to transmit disease to more than 700 million people annually in Africa, South America, Central America, Mexico, Russia and much of Asia with millions of resulting deaths. At least 2 million people annually die of these diseases. The principal mosquito borne diseases are the viral diseases like Malaria, yellow fever, dengue fever, Japanese encephalitis and so on.

Our professional technicians use mosquito trap and aerosol to kill the mosquito directly for mosquito control and prevention.

Fleas

Fleas

Fleas are pests of humans as well as ectoparasites of domestic animals and rodents.

Features

  • Small wingless insects with bodies laterally compressed
  • Their mouthparts can pierce the skin of their hosts
  • Long and powerful legs

All fleas are terrestrial. Adults of both sexes feed readily and repeatedly on blood of animals, humans and birds, but they may survive a long period of starvation. Fleas are attracted to their hosts by warmth and odor. The nests of the hosts are the normal breeding places of all stages of fleas.

Our professional technicians use insecticides to eliminate fleas and also reduce eggs and larvae.

Cockroaches

CockroachesCockroaches are the most common pests in many homes. Common types of cockroaches in Hong Kong include Periplaneta americana (American cockroach), Periplaneta australiasiae (Australian cockroach) and Blattella germanica (German cockroach).

Features

  • Cockroaches pass through three stages in their life cycle, i.e. eggs, nymphs and adults. Nymphs look like adults except that they are smaller in size, do not have wings and cannot reproduce;
  • Cockroaches can be found both indoors and outdoors ubiquitously where food is present;
  • They prefer dark, warm and moist environment and love to hide in cracks and crevices;
  • They are most active at night; and
  • They are omnivorous but prefer starchy food.

Hazards Caused by Cockroaches

  • Produce odorous secretions and have adverse effect on food quality;
  • Carry pathogens on their surfaces which can cause disease including food poisoning, nausea, vomiting and diarrhea;
  • Carry a wide variety of harmful microorganisms inside their body; and
  • Contain a number of allergens, in their excrement and their cast-off skins, which can cause rashes, watery eyes and sneezing.

Our professional technicians use insecticides and set poisonous bait to kill cockroaches.
