![]() ![]() Mating on or off a host, the female then takes a final and large blood meal over 7-14 days from a third host.The nymph also quests for a host from which it feeds for 5-8 days before dropping off to moult into an adult.After feeding for 3-5 days they drop off the host, digest the blood and moult (shed their skin) developing into the next growth stage, an 8-legged nymph. The larvae climb onto grass to wait for (quest) and ambush a passing host that they attach to and take a blood meal.Their eggs hatch producing 6-legged larvae. punctata are exophilic ticks living on top of the ground, albeit in humid undergrowth. Although not indigenous to the UK it has been identified on occasion on pets and in kennels and dwellings after import from mainland Europe and elsewhere and is a risk to pets being taken abroad under PETS to Southern Europe.It can reach high numbers in southern Europe with activity mainly between March and October.It is a tropical/subtropical tick, but can survive in temperate climates (central and northern Europe) when protected within domestic environments such as homes and kennels.Known as the brown dog tick, will utilise species such as cats, foxes and cattle as hosts but the dog is its preferred host.Can be brought by wild animals to drop off in gardens and parks near its habitats so that ticks and tick-borne diseases have been observed even in suburban gardens.There is then very little activity in winter, though occasional ticks can be found on an animal. Some ticks become active in the cooler autumn (August to October). In hotter areas of the UK tick activity can almost cease during summer, although larvae and nymphs may be active, and ticks remain active in cooler, damp locations. Activates in spring/early summer (March to May/June).ricinus maybe found in woodland even in drier areas such as East Anglia and in some East Anglian and South-Eastern coastal areas. The primary requirement is a thick basal vegetation layer that often occurs where there is poor drainage or poor soil and thick bedrock increases the level of moisture.Requires high humidity (almost saturation) to prevent dehydration on the ground so it tends to be found in wetter areas, particularly in the West and Northern England and Scotland.Feeds once at each developmental stage and, as the tick often feeds only once a year in the UK, the whole cycle from egg to adult can take three years.The higher frequency on pets compared with other ticks is related to its exophilic habits of searching for a host above ground meaning that passing pets easily become infected. Most common tick feeding on dogs and humans where nymphs and adults in particular are found.Ticks are normally inactive in winter, and become active to feed in the spring and early summer, then markedly reduce activity in the summer though, depending on species, stage and habitat, some ticks can be active throughout summer finally there is a second peak of activity in the cooler autumn. The habitat of these ticks varies with genus and species from very rural fields and woods, through rural and urban nests/lairs/burrows, to kennels and houses. sanguineus are occasionally found on pets. The ticks most commonly found on dogs and cats in the UK belong to the genus Ixodes ( I. All these are 3-host ticks, each stage feeding on a different host, although the 3 hosts could be of the same host species, or the tick may prefer very different host species for each feed. Rhipicephalus sanguineus, a tropical/subtropical tick, might be identified after importation on pets from Continental Europe and elsewhere. Dermacentor reticulatus and Haemaphysalis punctata also are indigenous and found occasionally on pets but only in specific areas. Other Ixodes species are only very occasionally seen. The ticks most commonly found on pets in the UK are Ixodes ricinus and Ixodes hexagonus and then Ixodes canisuga. Infections can be transmitted in saliva as the ticks feed or, more rarely, after the tick is accidently ingested.īoth hard (Ixodidae) and soft (Argasidae) ticks occur in the UK but it is the hard ticks that occur on dogs and cats. Generally, ticks are of most importance as vectors of bacteria, viruses, protozoa and nematodes, affecting both companion animals and humans. Ticks are temporary blood feeding parasites which spend a variable time on their hosts in the case of ixodid ticks, each stage feeds for only a short period of one to two weeks. ![]()
