I can be sitting outside without a fly in sight and the second I open a drink or food there is a swarm. How the heck to they find good sources so quickly?

What you do is put something out that will attract them not far from where you’ll be sitting. Do it before you sit down. They’ll all congregate there and be less annoying where you are. Works for us when we eat lunch outside.
