As Canadians spend more time outdoors during the summer months, the risk of tick bites continues to grow. Warmer temperatures have helped ticks expand their range across many parts of Canada, including regions where they were once considered uncommon. Public health experts are seeing increasing numbers of Lyme disease cases and other tick-borne illnesses, making prevention more important than ever.
For farmers, homesteaders, gardeners, and rural residents, understanding how to avoid tick bites and what to do after one occurs can help reduce the risk of serious illness.
Tick-Borne Diseases Are Increasing in Canada
While Lyme disease remains the most well-known tick-borne illness in Canada, blacklegged ticks can also transmit anaplasmosis, babesiosis, Powassan virus disease, and several other infections. Not every tick carries disease, and not every bite leads to illness, but awareness and prompt action are essential.
The Public Health Agency of Canada reports that tick-borne diseases have increased in recent years as tick habitats expand. Ticks are generally most active from spring through fall, but they can be found whenever temperatures rise above freezing.
Where Are You Most Likely to Encounter Ticks?
Ticks thrive in:
- Wooded areas
- Tall grass
- Brush and shrubs
- Overgrown fence lines
- Leaf litter
- Pastures bordering forests
- Gardens and parks
Although wooded trails are commonly associated with ticks, they can also be found around farmyards, field edges, and rural properties.
Public health officials note that infected ticks may be encountered almost anywhere in Ontario, Southern Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and southern Manitoba. Saskatchewan has seen the tick risk rise recently. BC is home to the western blacklegged tick, which can carry Lyme disease, although infection rates are generally lower than in eastern Canada. Alberta is considered a lower-risk province compared to Ontario and the Maritimes, but ticks can still be found,
How to Prevent Tick Bites
The best protection is to avoid being bitten in the first place.
Experts recommend:
Cover Up
Wear:
- Long-sleeved shirts
- Long pants
- Closed-toe footwear
- Light-coloured clothing that makes ticks easier to spot
Tucking pant legs into socks can provide additional protection when walking through tall vegetation.
Use Tick Repellent
Apply insect repellents containing DEET or icaridin according to label directions. These products can be applied to exposed skin and clothing and are effective at reducing tick bites.
Stay on Cleared Paths
When hiking or walking fields, avoid brushing against tall grass, brush, and dense vegetation where ticks commonly wait for hosts.
Check Yourself Daily
After spending time outdoors:
- Examine your body carefully
- Check children and pets
- Pay attention to the scalp, behind the knees, underarms, groin, waistline, and around the ears
- Shower soon after coming indoors
Prompt detection can significantly reduce disease risk.
Manage Tick Habitat Around the Farm
Reduce tick-friendly environments by:
- Mowing grass regularly
- Removing leaf litter
- Trimming brush near buildings
- Keeping frequently used areas clear and well maintained
These measures can help reduce tick populations around homes and farmyards.
What to Do If You Find a Tick
Finding an attached tick can be unsettling, but removing it properly is important.
Health Canada recommends:
- Use clean, fine-point tweezers.
- Grasp the tick as close to the skin as possible.
- Pull straight out with slow, steady pressure.
- Avoid twisting, crushing, or jerking the tick.
- Clean the bite area with soap and water or an alcohol-based sanitizer.
Do not attempt to remove a tick by:
- Burning it
- Covering it with petroleum jelly
- Applying nail polish
- Using essential oils
These methods may increase the chance of disease transmission.
After removal, you may wish to photograph the tick and submit the image to eTick, a Canadian tick identification platform. If you plan to consult a healthcare provider, placing the tick in a sealed container can be helpful.
Watch for Symptoms
Early symptoms of Lyme disease and other tick-borne illnesses may include:
- Fever
- Chills
- Headache
- Fatigue
- Muscle aches
- Joint pain
- Swollen lymph nodes
- An expanding red rash, often described as a "bull's-eye" rash
Symptoms can appear days or weeks after a bite. Some illnesses may progress if left untreated, making early medical assessment important.
When Should You Seek Medical Attention?
Contact a healthcare provider if:
- You develop symptoms after a tick bite
- You cannot completely remove the tick
- The tick was attached for an extended period
- You are concerned about possible exposure
In some situations, preventive antibiotic treatment may be considered when specific risk factors are present, including a blacklegged tick bite in a higher-risk area and prompt medical assessment following removal.
A Growing Concern for Rural Canadians
For many small farm families, ticks have become a routine part of working outdoors. While the risk of infection remains relatively low after any individual tick bite, awareness, prevention, and prompt removal are the best defences against serious illness.
As tick populations continue to expand across Canada, taking a few simple precautions can help keep you, your family, and your livestock safer throughout the outdoor season.
