japanese beetles

(Question)

for the past 3 years, my small garden has been infested and devoured by Japanese beetles comes end of July. I see them in many places around Toronto now and wonder whether the municipality can do something about spraying them so they do not reappear next year….They are pretty but tenacious and destructive and it is desolating to see how they destroy my beautiful roses and other leaves and flowers! Thank you

Thank you for your observation.  Given the pesticide ban in Ontario, it is unlikely that the municipality will spray to control Japanese Beetles.  Here is a link to a guide to natural controls prepared by the City of Toronto, if you want to try and control them yourself:

As well, here is a link to a detailed plan for control from Ask a Master Gardener:
