Question

thay are big and little thay are best when around

Answer 1

They are the LAST FLIES FALL and SUMMER, some MAMA FLY FLEW in, was IN the HOUSE hatchin' BABY FLIES, that you are not aware of + when the WEATHER is/was CRAZY as it was, this past WINTER, FLIES got CONFUSED by the SEASONS.

Answer 2

It cold outside.
Little ones may be like a fruit fly, look around the kitchen for vegetables or fruit laying out and put in the Fridge. Look if they around the trash and it have vegetable/fruit stuff there. Spray some killer into the trash, just a quick dusting.
