The wood tick, also known as Dermacentor andersoni, is a species of tick found in the western regions of North America, including the province of Alberta, Canada. These ticks are ectoparasites that feed on the blood of mammals and birds, and are known to transmit several diseases, including Rocky Mountain spotted fever and tularemia. In Alberta, wood ticks are commonly found in wooded areas, grasslands, and along trails and pathways, particularly during the spring and summer months.
Identification and Life Cycle
Wood ticks in Alberta can be identified by their brownish-gray color, with a distinctive white or yellowish marking on their back. They have a hard outer shell, or exoskeleton, and are typically around 1⁄4 inch (6-8 mm) in length. The life cycle of a wood tick consists of four stages: egg, larva, nymph, and adult. Female wood ticks lay their eggs in the spring, which hatch into larvae after several weeks. The larvae then feed on the blood of small mammals, such as rodents, before molting into nymphs. The nymphs feed on larger mammals, including deer and humans, before molting into adults.
Habitat and Distribution
In Alberta, wood ticks are found in a variety of habitats, including wooded areas, grasslands, and along trails and pathways. They are typically found in areas with dense vegetation, such as shrubs and grasses, where they can easily attach to passing hosts. Wood ticks are also found in urban areas, particularly in parks and green spaces. According to data from the Government of Alberta, the majority of wood tick sightings in the province occur in the southern and central regions, particularly in the areas around Calgary and Edmonton.

|---|---|
| Southern Alberta | 425 |
| Central Alberta | 315 |
| Northern Alberta | 120 |
Disease Transmission and Prevention
Wood ticks in Alberta are capable of transmitting several diseases, including Rocky Mountain spotted fever, tularemia, and anaplasmosis. These diseases can be serious and even life-threatening if left untreated. To prevent tick bites and reduce the risk of disease transmission, it’s essential to take precautions when spending time outdoors in areas where wood ticks are common. This includes wearing protective clothing, such as long-sleeved shirts and pants, and using insect repellents that contain DEET or picaridin. It’s also important to conduct regular tick checks after spending time outdoors, and to remove any attached ticks promptly and correctly.
Tick Bite Prevention and Removal
To prevent tick bites, it’s essential to wear protective clothing and use insect repellents when spending time outdoors in areas where wood ticks are common. When removing an attached tick, it’s essential to use fine-tipped tweezers and to grasp the tick as close to the skin as possible. The tick should then be pulled upwards with steady, even pressure, without twisting or jerking. After removing the tick, the bite area should be cleaned with soap and water, and an antiseptic applied to reduce the risk of infection.
