Visit Lyme disease in Quebec is no longer a rarity confined to a few isolated regions. Black-legged ticks, which can transmit the bacteria responsible for the infection, are gradually expanding their range and colonizing new areas of the province. This spread, observed by public health authorities, raises legitimate concerns among outdoor enthusiasts, families, and outdoor workers. Recognizing these ticks, understanding how they transmit the infection, and adopting the right preventive measures remain the best protections available to you.

Why Are Ticks Becoming More Prevalent in Quebec?
Visit geographic distribution The distribution of black-legged ticks changes from year to year. According to data from the Institut national de santé publique du Québec (INSPQ), the number of municipalities where these disease-carrying ticks are likely to be present continues to rise, particularly in the Capitale-Nationale and Chaudière-Appalaches regions. The Estrie and Mauricie regions remain the most affected, but the trend is clear: the at-risk area is expanding.
Public health experts point primarily to climate change. Milder winters and longer warm seasons create conditions favorable to the survival and spread of these ticks into new habitats. The movement of migratory birds and deer, which carry ticks over long distances, also accelerates this colonization.
Factors that promote expansion
- Shorter and milder winters, which reduce tick mortality
- The tick season has been extended, from spring to fall
- Passive transport of ticks by migratory birds and large mammals
- Urban sprawl along the edges of wooded areas, which increases contact
- Increase in the white-tailed deer population, the primary hosts of adult ticks
| Region | Risk level | Observed trend |
|---|---|---|
| Eastern Townships | High (epicenter) | Well-established risk |
| Mauricie | Raised | Well-established risk |
| Chaudière-Appalaches | On the rise | New sectors added |
| Capital National Region | On the rise | New sectors added |
How to Identify the Black-Legged Tick
Visit black-legged tick (Ixodes scapularis) is small and often harder to spot than one might think. When unfed, an adult tick measures 3 to 5 millimeters—roughly the size of a sesame seed. After feeding on blood, it can swell to the size of a pea. Nymphs, in their immature stage, are even smaller—about the size of a poppy seed—which makes them particularly easy to miss during a quick inspection.
Where do they live?
- Forests and Wooded Edges
- Tall grass and brush
- A pile of fallen leaves on the ground
- Hiking trails lined with vegetation
- Gardens and Lots Adjacent to Wooded Areas
Contrary to popular belief, ticks do not jump or fall from trees. They wait on the tip of a blade of grass or a leaf, legs outstretched, for a host to brush past so they can latch on. That’s why the legs and lower body are the first points of contact during a walk in nature.
Key Takeaways
- The black-legged tick is small: ranging in size from a sesame seed to a pea when engorged
- Nymphs are tiny and easily go unnoticed
- They live in tall grass, brush, and fallen leaves
- They don't jump or fall out of trees
- The lower body is the first point of contact
- Not all ticks carry the bacteria that causes Lyme disease
How Lyme Disease Is Transmitted
Lyme disease is caused by a bacterium of the genus Borrelia, transmitted to humans through the bite of an infected black-legged tick. Not all ticks carry this bacterium, so not all bites lead to infection. One factor, however, is crucial: how long the tick remains attached.
In general, the risk of transmission increases when a tick remains attached to the skin for an extended period of time—often described as ranging from several hours to more than a day. This is precisely why it is so important to remove a tick as quickly as possible. A thorough check after returning from an outdoor activity allows you to spot and remove ticks before they have time to transmit an infection.
| Factor | Effect on Risk |
|---|---|
| Uninfected tick | No transmission possible |
| Quick Removal of a Tick | Reduced risk |
| Prolonged attachment | Increased risk |
| Activity in an area known to be at risk | Increased vigilance is recommended |
Signs and symptoms to watch for
The symptoms of Lyme disease vary from person to person and change over time. The most characteristic sign is a red rash that gradually spreads around the bite site, sometimes described as a target or a ring. This rash, called erythema migrans, does not always appear and may go unnoticed depending on its location.
Symptoms sometimes reported in the early stages
- Redness spreading around the bite
- Unusual fatigue
- Fever or chills
- Headaches
- Muscle or joint pain
- Swollen Lymph Nodes
These symptoms are not specific to Lyme disease and may resemble those of other common conditions. That is why it is important to mention any recent exposure to a high-risk area or any tick bites during a medical consultation. Only a healthcare professional can assess the situation and determine the appropriate course of action.
Key Takeaways
- Erythema migrans is the most characteristic sign, but it does not always appear
- Early symptoms often resemble those of the flu
- Symptoms vary greatly from person to person
- Tell a healthcare professional about any recent injections or exposure
- The earlier the evaluation, the better the situation can be managed
- Self-diagnosis is never recommended for this condition

Preventing Tick Bites
Visit prevention is based on simple steps that are easy to incorporate into any outdoor outing. The goal is twofold: to reduce the chances of a tick attaching itself, and to maximize the chances of spotting it quickly if it has.
Before and During the Activity
- Wear long, light-colored clothing so you can spot ticks more easily
- Tuck the bottoms of your pants into your socks
- Stay in the middle of the trails, avoiding tall grass and brush
- Use an appropriate mosquito repellent, following the product instructions
- Check your pets when you return home
On the way home
- Check your entire body, paying special attention to the folds: armpits, behind the knees, scalp, nape of the neck, and waist
- Take a shower within a few hours after exercising
- Put your clothes in the dryer on a high heat setting to kill any remaining ticks
- Also check your backpack and gear
| Body area | Why Should We Pay Attention to This? |
|---|---|
| Scalp and Nape of the Neck | Hard to see, often forgotten |
| Armpits | A warm, sheltered area favored by ticks |
| Behind the knees | A skin fold that is frequently affected |
| Waist and Belly Button | A skin fold that's easy to miss |
| Groin | Areas to Be Inspected Routinely |
Key Takeaways
- Covering your skin and staying in the center of the trails limits contact
- Light-colored clothing makes it easier to spot ticks
- A thorough inspection upon return is the key step
- Skin folds are the areas most likely to be overlooked
- The high-temperature dryer removes any ticks that remain on clothing
- Pets must also be inspected
What to Do If You Get Stung
If you find a tick attached to your skin, the golden rule is to remove quickly and properly. Early and proper withdrawal reduces the risk of transmission. Here are the steps generally recommended by health authorities.
- Use a pair of fine-tipped tweezers or a tick remover—never your fingers
- Grasp the tick as close to the skin as possible, by the head
- Pull gently and steadily, without twisting or crushing the tick's body
- Then clean the area with soap and water or a disinfectant
- Write down the date of the bite and watch for symptoms
After removing the tick, it is advisable to consult a pharmacist or healthcare professional to determine whether preventive treatment is necessary, depending on the circumstances and region. Do not crush the tick between your fingers, and avoid questionable methods (nail polish, matches, oil) that may actually increase the risk.
Key Takeaways
- Remove the tick quickly using fine-tipped tweezers or a tick remover
- Grab it close to the skin and pull without twisting
- Never use your fingers, nail polish, oil, or a match
- Disinfect the area after removal
- Write down the date of the injection
- Contact a pharmacist or healthcare professional to discuss next steps
Myths and Misconceptions
«Ticks fall from trees onto their victims.»
False. Ticks do not jump or fall from trees. They wait, clinging to low vegetation, for a host to brush past them. Contact most often occurs on the legs and lower body.
«Every tick bite causes Lyme disease»
False. Not all ticks carry the bacteria, and even when they do, transmission depends largely on how long the tick remains attached. Removing the tick quickly significantly reduces the risk.
«You have to burn the tick or smother it with oil to get it to let go.»
False. These methods are not recommended. They can stress the tick and cause it to regurgitate, which would increase the risk. Mechanical removal with fine-tipped tweezers remains the only recommended method.
«Lyme disease affects only certain remote areas.»
Nuanced. While certain regions have a higher concentration of cases, the at-risk area is gradually expanding across Quebec. It’s best to adopt the right preventive measures as soon as you’re in a wooded or grassy area, no matter where you are.
«There's nothing you can do once you've been stung.»
False. On the contrary, there are several helpful steps you can take: stop using the product immediately, monitor your symptoms, and consult a pharmacist or healthcare professional to determine whether preventive measures are necessary.
Frequently asked questions
At what time of year are ticks active?
Black-legged ticks are most active during the warm season, from spring to fall, when temperatures are mild. As the seasons become longer, their active period tends to extend. It’s important to be vigilant as soon as the snow melts and the ground warms up.
How long does a tick have to remain attached to transmit the infection?
The risk of transmission increases with the duration of contact, which is often described as ranging from several hours to more than a day. That is why prompt removal is so important. A routine inspection upon returning from an activity allows for action to be taken before that time elapses.
Should you see a doctor after every tick bite?
After removing the tick, it is generally recommended to contact a pharmacist or healthcare professional, who can assess the situation based on the region and circumstances. A consultation is necessary if symptoms develop in the days or weeks that follow.
Can pets bring ticks home?
Yes. Dogs and cats that spend time in grassy or wooded areas may carry ticks. It is recommended that you check them when you return home and talk to a veterinarian about appropriate preventive measures.
Can you get stung in your own backyard?
This is possible, especially if the yard borders a wooded area or has tall grass and piles of fallen leaves. Mowing the lawn regularly, clearing away leaves, and creating a border between the lawn and the woods can help reduce the number of ticks.
Can Lyme disease be treated?
When diagnosed early, Lyme disease is generally treatable. Prompt evaluation by a healthcare professional plays an important role. If you have any questions about treatment, only a doctor or pharmacist can advise you based on your specific situation.
