Hundreds of infected ticks found in one yard in Canada

Four of the citizen scientists collectively recovered several hundred ticks over a 3-year period starting in 2014. The Saint John, New Brunswick collection process went beyond conventional flagging. “Ticks were obtained by flagging backyard vegetation with a white hand towel, removing ticks from flowers harvested in the backyard, and collecting ticks from the household cat,” according to the study, published in the journal Healthcare.

Ticks at multiple life stages, including larval, nymphal and adult ticks, were collected in the family’s backyard. The number of ticks sampled increased over the 3-year study period. Participants collected 47 larva, 372 nymphs, 15 female adult, and 1 male adults.

According to Lewis, 15% of the sampled ticks in the family’s backyard (the Saint John site) tested positive for B. burgdorferi by nested PCR. At other locations, such as the Nova Scotia site, 30% of the sampled ticks tested positive for the Lyme bacteria, while 7% were infected at the Hampton site. Some sites were completely free of ticks. At one site, none of the sampled ticks were infected.

The authors suggest the low rate of ticks collected at some sites may help counter what they refer to as “tickophobia” and may provide “an increased sense of personal security outdoors and empowerment that can lead to increased use of outdoor areas for recreation.”

The number of infected ticks found in other locations, however, is concerning.

    Why is this not being more public. Even scarier then covid 19.
    My wife suffers from Lyme disease and even when you know you have it, there is no treatment. Who wants to watch anyone in their family suffer from this. A remedy needs to be found. Eliminating the world of ticks is an impossible solution.
    A course of antibiotics if you catch it early is not enough.

    A lot of people are suffering their worst nightmare with this disease. They need to be helped.

  2. It’s Saint John NB – we do not abbreviate.

    Is this study from Saint John, New Brunswick or St. John’s, Newfoundland?

    1. Thanks for the question. “St. John region which includes the communities of St. John, Rothesay, Quispamsis, and Hampton in southwestern New Brunswick, a Canadian Atlantic province.” writes the author. I corrected the blog to read Saint John.

  4. I believe this is very important info. And it reinforces my belief that local Public Health Units should release to the public the specific results of their tick flags. This includes the location of each drag and the results; also the coinfections that were found. The public is paying for this and should be informed so they can protect themselves.
