Ridiculous insects

I can't take it anymore!! We've got like a dozen flies in our dining room. We were down to about 3 day before yesterday because Lori is phenomenal at killing them without a fly swatter (which apparently we don't have). But they're multiplying. Quickly. And they're much more aggressive than typical flies... slight movements do not frighten them and they have a tendency to land on our heads and just stay there. I have to wave my arms around like some standing-on-the-corner-religious-nut-case to get them to fly off and then they come right back again anyway. And what are they doing in here in November??? This is not the right season. Annoying :|
