This weekend marks the unofficial start to summer, and that means Canadians are about to start spending a lot of time outdoors. Unfortunately, a reality of outdoor Canadian life is blackflies and mosquitoes, and the annoying bites they leave on us.Canadians hate bugs so much, in fact, that a recent survey by Vision Critical found that more than half of Canadians (53 per cent) have stayed indoors to avoid being bitten during the summer season, losing almost two days in total of relaxing outdoor time.
