An Unusual Fascination with Ticks

When Nicoletta Faraone, a chemistry professor at Acadia University, embarked on a walk in Wolfville, her disappointment at not finding any ticks was unexpected. However, during another stroll in New Minas, she discovered a staggering 300 ticks in just two hours, and that thrill made her day. "Ticks may gross people out, but I find them fascinating!" she declared.

Ticks on the Rise: The Impact of Climate Change

As global warming drives these pests northward, Nova Scotia is increasingly becoming a prime habitat for ticks. Faraone warns that we can expect their populations to grow, along with the potential introduction of new species like the Lone Star tick, which can trigger a red meat allergy in humans.

Know Your Ticks: The Species to Watch Out For

In Nova Scotia, the main offenders are the dog tick and the blacklegged tick. While both can carry harmful pathogens, the blacklegged tick, also known as the deer tick, is notorious for transmitting Lyme disease. These ticks, typically found in shaded, forested areas, prefer tall grass and have females about the size of a sesame seed.

Dog ticks thrive in sunnier, open locations and can carry dangerous diseases such as Rocky Mountain spotted fever and tularemia.

Stay Calm: Understanding Tick Transmission Risks

Health Canada reassures that ticks need to be attached for 24-48 hours before they can transmit pathogens. This means that if you find a tick shortly after returning from a walk, there’s a good chance you’re in the clear.

Faraone stresses the importance of regular tick checks after your outdoor adventures. "If you remove a tick within 24 hours, you're likely safe," she advises.

Tick Habits: Where They Like to Hide

Ticks favor warm, moist spots on the body, such as behind the ears, in the armpits, and in the hair. If you do find one, especially if it’s been attached for a longer duration, seek advice from local pharmacies where antibiotics may be prescribed.

Understanding the Tick Life Cycle

Blacklegged ticks begin their life cycle as tiny nymphs and often latch on to migratory birds or small mammals to feed. It’s during this initial feeding that they can contract pathogens like Lyme disease. After feeding, they molt and mature over time, eventually finding larger mammals for their next meal and possibly transmitting diseases.

Prevention is Key: Tips to Avoid Tick Encounters

Ticks rely on scent and vibrations to latch onto us while we’re outdoors. Thus, maintaining a well-mowed lawn can significantly decrease their presence around your home. Interestingly, recent research by Faraone’s team indicates that lemongrass essential oil hampers ticks’ ability to smell, but Health Canada has yet to endorse it for commercial repellent products. Eucalyptus oil and DEET remain effective options.

Ultimately, Faraone advises, "Just remember to wear repellent—don’t let ticks keep you from enjoying the great outdoors this spring!"
