Ottawa to set up deer baiting to fight ticks
HRM spokesman says such stations have reduced black-legged tick populations in the U.S.

By JOHN McPHEE Staff Reporter

White-tailed deer will be getting a dose of pesticides along with their treats as part of an effort to fight Lyme disease in the province.

Deer bait stations are expected to be installed as part of a federal study in Bedford and outside Lunenburg next month, an official with Halifax Regional Municipality said Monday.

Similar stations have been very effective in reducing black-legged tick populations in the United States, said Richard MacLellan, manager of HRM’s sustainable environment management office.

"We’re hoping obviously to have the same sort of results up here," MacLellan said. "This will have a tremendous impact in reducing the (deer) tick population in Nova Scotia."

Black-legged ticks carry the bacteria that cause Lyme disease. These insects are smaller than the more common wood tick, also called the dog tick, which do not carry the disease.

From four to six bait stations will be placed in Admirals Cove in Bedford for two years, MacLellan said. Food placed in the stations lure the deer, and after the animal sticks its head in, rollers coated with "tickicide" rub against its neck.

It’s believed that two bait stations will be placed in Lunenburg County as part of the study, which is being conducted by the Public Health Agency of Canada. Researchers want to know how effective the bait stations are in reducing the black-legged tick population.

The researchers doing the work could not be contacted Monday.

"Initially the project was happening in Lunenburg," MacLellan said. "After our issues (in Bedford) came to a head in the last six months, I begged, pleaded, pushed and prodded to get us included and we were."

Besides Admirals Cove, the black-legged tick is known to be established in Gunning Cove, Shelburne County; Melmerby Beach, Kings Head, Pine Tree and Egerton in Pictou County; and Heckmans Island, Blue Rocks, Garden Lots and First Peninsula in Lunenburg County.

Lyme disease is an inflammatory illness causing swelling of the joints, fever, fatigue, headache and muscle aches. It can lead to heart problems, chronic joint trouble and a type of facial paralysis called Bell’s palsy if left untreated.

Common antibiotics are usually effective in treating the disease.

Fifty cases of Lyme disease have been treated in N.S. since 2002.

Pesticide not approved in Canada for use on park ticks

Pesticide not approved in Canada for use on park ticks

By CHRIS LAMBIE Business Reporter

The head of the company that’s about to spray a Bedford park for ticks fears Health Canada may nix the proposal.

The pesticide Dragnet is not approved for use in this country against blacklegged ticks, which can carry Lyme disease. But that’s the same substance Halifax Regional Municipality plans to pay a pest control firm $15,000 to spray in Admirals Cove Park next month.

"It’s a strange situation. There’s no ifs, ands or buts about it," said Don McCarthy, president of Braemar Pest Control Services.

The labels on Dragnet say it can be used in Canada against brown dog ticks and a whole host of other insects, he said.

"It doesn’t mention the 15 other kinds of ticks that there are," McCarthy said.

Every use of an insecticide wouldn’t likely fit on a label, he said.

"The label would be the size of an encyclopedia."

He has asked Health Canada’s Pest Management Regulatory Agency for permission to use Dragnet in Bedford.

"We’re still waiting on that decision. I’m not 100 per cent sure which way they’re going to go."

If the regulator refuses to grant permission, he plans to ask for an "emergency" approval because this is a human health issue.

Four people who live near the park have contracted Lyme disease. The serious inflammatory condition produces flu-like symptoms and joint pain.

"If they do come back and say, ‘No, we don’t want you doing this,’ then we’ll have to look at other alternative," McCarthy said, noting a garlic-based spay is a possible option.

Dragnet is registered for outdoor tick control in the United States, he said.

"On the 49th parallel, things don’t just change. If they’ve got the testing done by the (Environmental Protection Agency in the U.S.), why wouldn’t Canada accept them?"

A Kentville employee with the Pest Management Regulatory Agency referred questions about the problem to Ottawa.

More than 24 hours after fielding a reporter’s query about Dragnet, Health Canada was unable to provide someone to discuss the situation in an interview.

"The proposed use of Dragnet is not currently on the product label," department spokeswoman Ashley Lemire said late Wednesday in an email.

"However, Health Canada can grant an emergency registration for use of a pesticide to control pest infestations that can cause significant economic, environmental or health problems. Health Canada will be providing the municipality with information on how to submit an emergency registration application for this proposed use."

Dragnet is "clearly effective in the United States" for use against blacklegged ticks, which are also known as deer ticks, said Richard MacLellan, manager of Halifax Regional Municipality’s sustainable environment management office.

"There is no product in Canada that’s approved for deer ticks," MacLellan said. "That’s why we’re looking for anything."

The problem is there’s a "very small market for it in Canada because the problem with the ticks is relatively new and there’s probably only a couple of thousand dollars worth of product sales in Canada for a year."

Testing to get approval to use a pesticide on the ticks in Canada could cost hundreds of thousands of dollars, he said.

"So it just doesn’t make sense for a registrant to bring a new product in specifically for deer ticks," MacLellan said.

The pesticide contains permethrin, a chemical used in flea treatments for dogs and even in the uniforms of Canadian soldiers in Afghanistan.

MacLellan is hoping regulators allow the municipality to spray Dragnet to kill blacklegged ticks.

"It’s approved for a bazillion things up here, and it’s used in Canada on a bazillion things up here. Common sense and logic would tell you that it’s an appropriate use."

Dragnet is permethrin. It doesn't seem to have the piperonyl butoxide synergist with it (but it is something to ask about) - it is not listed on this MSDS. Instead, it contains a lot of some alkyl biphenyl mixture and aromatic hydrocarbons - those are pretty toxic! Hard to understand why the biphenyls would be "not classified" - that is willful blindness.

Chemical Name CAS# Wt.% EC No. EC Class
Permethrin 52645-53-1 36.8 258-067-9 Xn-N; R20/22-43-50/53
Alkyl biphenyl mixture 69009-90-1 <27 273-683-8 Not classified
Aromatic Hydrocarbons 64742-47-8 <14.1 265-149-8 Xn; R65
Surfactant Blend <7.6 None Not classified
