In Ontario, the blacklegged tick (deer tick) is of particular concern, as it can transmit Lyme disease. These ticks are most active in the spring and summer but can be found year-round when temperatures are above freezing. To prevent tick bites, wear light-colored clothing, use insect repellent, and check for ticks after being outdoors.
