Elevated tick activity
Think thermometer, not calendar
Ticks can be active even in colder weather. They survive the winter, protected under snow, leaf litter, or brush. Blacklegged ticks can be active any time temperatures are 4°C and above, including mild days during the winter months.1
Ticks can have serious consequences
Ticks are not only unsightly, they can also transmit agents that cause disease, like Lyme disease. Ticks are expanding their range in parts of Canada.
Help protect your pet before exposure
Being aware of the risk in your local area is an important part of protecting your pet and yourself. In addition, tick control medications can be initiated prior to the start of tick activity to help optimize protection for your pet. Talk to your veterinarian for more information.
