I see Yellow!

All the sudden there are these little flies all over the place. They are where I am, where my food is, where my coffee is.
It is January - where do they come from? No new plants, all fruits and vegetables covered. I checked all plants etc.

I've been catching them by hand and now I'm trying a glue trap.
When this one was caught while I was sitting on the table I had my blip.
And when it first walked and then flew away from the glue strip my face would have been blipworthy...
Only one thing left to say: No fly was harmed in the making of this blip.

Wish me luck for tomorrow.
