Common ticks found in HK includes Rhipicephalus sanguineous (Brown dog tick) and Boophilus microplus and they belong to the family IXODIDAE with size around 1/8″ (dark brown to black color). Ticks are efficient vectors of number of serious dieases of humans and domestic animals i.e. Q fever and boutonneuse fever etc. Ticks are arthropods, like spiders. Ticks occur in two basic forms and are thus divided into two famialies: Ixodidae (Hard tick), and Argasidae (Soft tick). Hard and soft, when describing ticks, refers to presence or absence of a hard plate on their back, called scutum. Ticks are bloodsucking ectoparasites of mammals, reptiles and birds.

Life Cycle

All ticks have four life stages: the egg and three parasitic stages that feed on the blood of vertebrates, two immature stages (larva and nymph), and the adult stage. Brown dog tick female lays from a few hundred to more than 5000 eggs in cracks and crevices. The six-legged larvae hatch after the eggs have incubated for 40-60 days. To moult to the next stage, the larval tick must obtain a blood meal (eight-legged nymphal stages, and an eight-legged adult stage).

Once a suitable host is found, the larvae will blood feed for 4-6 days, drop from the host and moult to the eight-legged nymphal stage. Nymphs require a further blood meal for 4-8 days before moulting to the adult stage. After feeding once more, the adult female hard ticks lay one batch of thousands of eggs and then die.

The time to completion of the entire life cycle may vary from less than a year in tropical regions to over three years in cold climates, where certain stages may enter diapause until hosts are again available. Many hard ticks can go for several months without feeding if not unduly duressed by environmental conditions.

Problems associated with ticks

Ticks are blood feeding external parasites of mammals, birds, and reptiles throughout the world. Approximately 850 species have been described worldwide (Furman and Loomis 1984). There are two well established families of ticks, the Ixodidae (hard ticks), and Argasidae (soft ticks). Both are important vectors of disease causing agents to humans and animals throughout the world. Ticks transmit the widest variety of pathogens of any blood sucking arthropod, including bacteria, rickettsiae, protozoa, and viruses. Some human diseases of current interest in the United States caused by tick-borne pathogens include Lyme disease, ehrlichiosis, babesiosis, rocky mountain spotted fever, tularemia, and tick-borne relapsing fever.

Dogs are susceptible to Lyme disease and may develop arthritis or lameness, lethargy, loss of appetite, disease of the lymph nodes, or other clinical conditions after being infected. Other animals including cats, horses, and livestock can become infected with Borrelia burgdorferi, but rarely develop clinical signs. Consult a veterinarian if you suspect that your dog has Lyme disease, or if you wish to consider protecting your dog(s) with one of the commercially available canine Lyme disease vaccines. Highly effective pesticide-impregnated tick collars also are available to protect dogs that are exposed to tick-infested environments.

Preventing Ticks

The best method of avoiding ticks is to stay away from known tick infested areas. If visiting such areas, wears light coloured clothing, as ticks will be much easier to detect. Trousers should be tucked into socks and shirts into pants. Natural repellent likes SmellGREEN® solution can be applied, with this repellent applied to the footwear and clothing.

All clothing should be removed on returning home and placed into a hot dryer for 20 minutes, which will kill any ticks that may still be on the clothing. Note that ticks can wander on the body for some two hours before attaching, make sure you search well for ticks, especially behind the ears and on the back of the head. Children and pets should be examined for ticks after visiting bushland/infested areas.


The Paralysis tick is very susceptible to dry conditions and so decreasing moisture can lessen their impact. Turn on dehumidifier or air-conditioner especially in Spring and Summer.

Thoroughly and regularly clean areas where adult ticks, tick larvae, and tick eggs are found. Vacuum floors, rugs, carpets, upholstered furniture, and crevices around baseboards and cabinets daily. Use a small pair of curved forceps or tweezers.

If possible, wear some sort of hand protection such as gloves so you don’t spread bacteria from the tick to your hands. Using the tweezers, carefully flip the tick over onto its back. Grasp the tick firmly with the tweezers as close to the skin as possible. Apply gentle pulling until the tick comes free. Twisting or turning the tick does not make removal easier because the mouthparts are barbed, not spiraled. Once removed, don’t crush the tick because you may transmit disease. Rinse it down a sink or flush it down a toilet.
