The odd mosquito has been out the last couple of weekends already. You should be good for blackflies but I would pack the bug shirt just in case. 

Last year I had a portage trip, the 13-15th.  No issues with mosquitoes and the black flies were flying around but not biting.  They still weren't out in full either.  My father and I were fine without any bug protection and my son (4) was fine with just a head net (bugs flying into his face were bothering him).

We didn't have to worry about any bugs the 14th as it rained which turned to snow and the 15th was still cool When we left so no bugs.


I'm heading up for a backpacking trip next weekend.  I may bring a headset as precaution but I'm not expecting to have to use it.

Ya they shouldnt be too bad for you.  I was just up in Haliburton and there was the odd mosquito.  It has been very warm this spring with lots of rain so I would pack bug jackets anyways just to be safe.  I bring one every trip into algonquin.  Saved my sanity many times.
My buddies and I are heading in for 3 nights on May 26th...I am expecting black flies and mosquitos in biblical proportions lol.

Of course, you can always camp in the "bug free" zones all across Algonquin Park.

Can I ask how one might find these zones?
