How bad are the blackflies in mid july
The black flies should be mostly gone by mid July. You'll still have mosquitos at dawn and dusk, and you might be bothered by deer flies or horse flies.
Will there be black flys around the 23 june
When are they at their worst?
As noted in post #1 ... they are gone by mid-July ... often earlier. Usually at their peak in early June. They will then be replaced by mosquitoes ... equally hungry & ferocious. They tend to die down by mid-August, although still present through to September.Edited: 25 June 2018, 01:25
