Unfortunately, with the description of "annoying little flying insects," I don't have anything to go on.  Ask an Expert staff are not located in your county or close to the Grand River so anything is going to be a guess.

These could be anything from mosquitoes to black flies to some kind of small fish fly.  I have no information to even make a guess from.

What an unbelievably stupid answer!!! Any three-year old in this country knows what a mosquito looks and feels like! What do you take me for?? If you are paid for this level of incompetence, you should be fired! I hope your supervisor has a quality control program in place to discover you!  W.A.Palutke, M.D. I have a high quality photo but I would obviously wasting my time to send it to you.

Thank you for your time.  It's been a pleasure getting to meet you.
