Wasps and hornets can turn a beautiful Cornwall, Ontario summer into a nightmare, and unfortunately, we see plenty of both here. The moderate pest prevalence in Cornwall means you're likely to encounter wasps and hornets during the warmer months, especially from spring through fall. Our cold winters with an average temperature of 6°C actually give us a bit of a break, but the warm summers create ideal conditions for these stinging insects to thrive. If you've spotted a nest or had a close encounter with wasps or hornets in Cornwall, it's time to call in the professionals.
