Problem is there is no mentioning of deer ticks (Ixodes)!
Revolution is supposed to be also good against dog ticks, but unfortunately my dog picked up plenty of ticks. In retrospect, this is not surprising:
Lyme disease is an infection caused by the corkscrew-shaped bacteria, Borrelia burgdorferi. In Ontario, these bacteria are spread by the bite of blacklegged ticks (formerly called deer ticks), Ixodes scapularis. The blacklegged tick can be found sporadically throughout the province....
In Ontario, blacklegged ticks are more commonly found in rural areas along the north shores of Lake Erie, Lake Ontario, and the St. Lawrence River. Locations with established blacklegged tick populations infected with Lyme disease include: Long Point Provincial Park, Turkey Point Provincial Park, Rondeau Provincial Park, Pinery Provincial Park, Rouge Valley, Point Pelee National Park, Prince Edward Point National Wildlife Area, Wainfleet Bog Conservation Area, and the Thousand Islands National Park area. The precise boundaries of these established tick populations are difficult to define but it is anticipated that some of these populations will continue to expand into neighbouring areas. Blacklegged ticks are also known to feed on migratory birds and as a result, they can be transported throughout the province. Therefore, while the potential is low, it is possible for people to encounter blacklegged ticks, or to be infected with Lyme disease from the bite of an infected blacklegged tick, almost anywhere in the province.
