Ticks in Ontario


Ticks are eight legged parasites that have highly developed mouthparts that pierce through the skin of animals and feed on their blood. Ticks feed on a range of animals, from cats, dogs, horses, squirrels, various birds, to humans as well. 

unfed ricks are flat, in a tear drop shape. Adult ticks have 6 legs and an antenna on their head. Depending on the species of tick, life stage, and sex, they can differ in color. After taking in blood, ticks grow and become bloated. 


Ticks have not only been increasing in number, but have also expanded across the country in the past five years. this is due to an increase in warmer temperatures and the dispersion of ticks on animal hosts. Because of this expansion, there has also been an increase in cases of disease transmission in many animals.

Most common species of ticks in Canada include:

  • deer ticks
  • american dog ticks
  • brown dog ticks
  • lone star ticks

These ticks carry different transmittable diseases if they bite and feed long enough.

Ticks can be found around the home, such as on the bed, carpets, floors, or sofas. In this case, it is important to take a close examination of your pets' fur and skin.

Tick bites usually do not hurt when they bite as they generally go unnoticed. Pets can have an allergic reaction to a bite, causing itchiness and or sensitivity at the site of the bite, but this is very rare.
