Ticks are spreading north in Canada as climate change warms habitats
Tick spread in Canada is rising as warmer weather opens new regions Protect yourself outdoors with expert prevention tips that help lower Lyme risk
Climate change is allowing ticks to move into new areas across southern Canada, and researchers say their spread is likely to continue. Scientists say the pests are advancing north from the United States and are now found in more parts of the country than in past decades.
Experts interviewed by CBC say blacklegged ticks, which can spread Lyme disease, have become a growing concern in places that previously saw few ticks. They note that warmer springs and longer summers help ticks survive and reproduce, while birds and other animals also carry them into new regions.
Researchers say Canadians should keep spending time outdoors, but with more precautions. They recommend wearing protective clothing, using insect repellent, checking for ticks after being outside, and taking steps to reduce tickfriendly areas around homes.
