How is Lyme disease spread? Lyme disease is an infectious disease spread through the bite of infected ticks. There are two types of ticks that can spread Lyme disease in Canada: blacklegged tick (or deer tick, Ixodes scapularis) in southeastern and south-central regions of Canada western blacklegged tick (Ixodes pacificus) in British Columbia Ticks need blood to survive, so they attach on animals and humans to feed. Ticks become infected with Lyme disease bacteria by feeding on infected wild animals, such as: birds rodents Once infected, ticks can spread the bacteria to humans and pets, particularly dogs. In most cases, the infected tick must attach and feed for at least 24 hours before the bacteria can be transmitted. Most humans are infected through the bite of immature ticks that are approximately the size of a poppy seed, called nymphs. Adult ticks, approximately the size of a sesame seed, can also spread Lyme disease. Ticks are very small and their bites are usually painless, so you may not know that you have been bitten. Blacklegged ticks are most often found in wooded or forested areas, in leaf litter or on shrubs and tall grass in some parts of Canada. Blacklegged ticks in at risk areas of southeastern and south-central Canada are more commonly infected.

This figure shows the size and colour of female blacklegged ticks in various stages of feeding.

How is Lyme disease spread?

Lyme disease is an infectious disease spread through the bite of infected ticks. There are two types of ticks that can spread Lyme disease in Canada:

blacklegged tick (or deer tick, Ixodes scapularis) in southeastern and south-central regions of Canada
western blacklegged tick (Ixodes pacificus) in British Columbia

Ticks need blood to survive, so they attach on animals and humans to feed. Ticks become infected with Lyme disease bacteria by feeding on infected wild animals, such as:

birds
rodents

Once infected, ticks can spread the bacteria to humans and pets, particularly dogs. In most cases, the infected tick must attach and feed for at least 24 hours before the bacteria can be transmitted. Most humans are infected through the bite of immature ticks that are approximately the size of a poppy seed, called nymphs. Adult ticks, approximately the size of a sesame seed, can also spread Lyme disease. Ticks are very small and their bites are usually painless, so you may not know that you have been bitten.
