Moose are bringing ticks into Prince George resident's yards

'These ticks do not pose any health risks to humans'.

Spring may officially be here, but Prince George residents have been reporting finding winter ticks outside and in their yards.

These ticks can often be found in the fur of moose, which is not an uncommon animal to find roaming around the Northern Interior city.

"I have been receiving a number of emails concerning winter ticks on cattle and horses and especially moose," said Courtney Jones, program co-ordinator for the winter tick survey program.

The province has an online winter tick survey program, so the public can report any moose they see affected by the parasites.

The reports of ticks in the area are not too surprising, said Jones.

"There are 32 species of ticks in Canada, and they don't discriminate between what animal they are found on," she told Daybreak North host Carolina de Ryk.

While ticks are a threat to moose, Jones said the public doesn't need to be too concerned for their own health.

"These ticks do not pose any health risks to humans in terms of championing disease to humans or domestic animals."

In high numbers, winter ticks can be a concern for some pets like cats or animals, but in low numbers they can be removed from their fur, like any other tick, said Jones.

Winter ticks do not transmit diseases like Lyme disease the way some others do, she added.

Risk to moose When ticks accumulate, it causes moose to scratch their fur, which makes them lose some of their fur.

"[This removes] a lot of their outer coat and guard hairs, which they need to keep them warm in this still kind of transitional cold period," said Jones.

Winter ticks often accumulate around the shoulders, and in bad cases, they will move down to the rear, haunches and belly of the moose, she added.

"It's really weakening them ... all this time spent grooming and itching is taking time away from foraging for the moose."


Moose are particularly affected by winter ticks because they are more solitary animals. Animals in herds usually will remove ticks from each other, said Jones.

Moose-killing ticks draw close attention of researchers "Moose are stimulus groomers, so other animals will consistently remove ticks from fall all the way up till now," she said.

"However, moose allow ticks to accumulate, because they only really start itching and scratching and removing them in response to the ticks biting them, which is right about now."
