A single, pinhead-sized blacklegged tick can carry a pathogen that alters your health for years. As summer temperatures climb and outdoor activity peaks, the risk of encountering these vectors in the Sudbury and Manitoulin districts is at its highest point of the year.

Public Health Sudbury & Districts (PHSD) issued a fresh advisory this week, emphasizing that Lyme disease is no longer a distant threat but a local reality. While the outdoors remains a primary destination for residents, the agency is urging a shift in behavior: treating every hike, garden session, and walk through tall grass as a potential exposure event.

The Simple Defense Against Tick Bites

Prevention is largely a matter of visibility and barriers. Because blacklegged ticks—often called deer ticks—are small and often painless when they bite, they can remain attached for hours without the host noticing.

PHSD recommends a multi-layered approach to minimize exposure:

  • Strategic Dressing: Wear light-colored clothing to make dark ticks stand out. Tucking pants into socks creates a physical barrier that prevents ticks from crawling up legs.
  • Chemical Barriers: Use Health Canada-approved insect repellents, strictly following the application instructions on the label.
  • Post-Activity Hygiene: Showering shortly after returning indoors can wash away unattached ticks.
  • Heat Treatment: Placing outdoor clothing in a dryer on high heat for at least 10 minutes is an effective way to kill ticks that might be clinging to fabric.

How to Safely Remove a Tick

If you find a tick attached to your skin, the speed of removal is the most critical factor in preventing the transmission of Lyme disease. The bacteria responsible for the illness typically require a period of attachment—often 24 to 48 hours—to migrate from the tick to the human host.

To remove a tick, use fine-tipped tweezers to grasp the insect as close to the skin as possible. Pull straight up with steady pressure; avoid twisting, which can cause the tick’s mouthparts to break off and remain in the skin. Once removed, disinfect the bite site and your hands with rubbing alcohol or iodine.

"People enjoying the outdoors need to check for ticks immediately after activities like gardening or hiking," said Ashley DeRocchis, an environmental support officer with PHSD. "This is one of the simplest ways you can protect yourself from Lyme disease."

Identifying the Threat

Not every tick carries the bacteria that causes Lyme disease, but identification is key to assessing risk. PHSD encourages residents to place removed ticks in a dry container for official identification at a public health office. Alternatively, high-quality photos can be submitted to etick.ca for expert review.

Key Takeaways

  • Check immediately: Perform a full-body tick check as soon as you return from any outdoor activity, especially in wooded or grassy areas.
  • Heat is effective: A 10-minute cycle in a high-heat dryer is sufficient to kill ticks on clothing that might otherwise survive a standard wash.
  • Watch for symptoms: Monitor your health for fever, headache, joint pain, or the characteristic "bullseye" rash in the weeks following a potential exposure.

What Experts Say

Public health officials emphasize that while the risk of Lyme disease is real, it is manageable through vigilance. The focus remains on early detection—both of the tick itself and of the early clinical signs of infection. If you develop a fever or the telltale expanding circular rash, seek medical attention promptly, as early antibiotic intervention is highly effective at preventing long-term complications.

As the season progresses, PHSD will continue to monitor tick populations across the region. The next major update on local infection rates is expected in late August, when the agency will evaluate whether current prevention efforts have successfully curbed the number of reported cases compared to last year.
