Ottawa Public Health started tick dragging in city parks on Wednesday in order to test the bugs they catch for Lyme disease.
Large squares of fleecy cloth are taped to a pole and then brushed over grass and wooded areas. "The ticks will actually cling to the cloth as we drag it over the grass," said Kristen MacNeil, a public health inspector who volunteers with the Lyme disease monitoring and surveillance program.
