In case anyone’s wondering where that’s from, it’s Earthbound.
So, apparently we have cluster flies:

(Don’t click the link if you don’t want to see a picture of a very small fly.)

… that looks right…
Brad @ Work says:
IDENTIFYING THE CLUSTER FLY
They average between 1/4 to 3/8 inch long. They are dark gray, never metallic blue or green. When crushed, they give off an odor like buckwheat honey. Cluster flies closely resemble house flies, but they are usually larger and have a yellowish sheen on the thorax.

If you have unseasonably warm weather in the late fall or winter, they may emerge thinking it is spring, going for the warmer air outside. They fly very slowly when they just wake up. They are strongly attracted to light, so they are usually found around windows. At night they are attracted to lamps.
Kit-Kat says:
Great! How do we get rid of them? >.>
Brad @ Work says:
Cluster fly problems can be partially prevented, but after the fall little can be done. All of those currently found within the home had infiltrated walls months ago.
A “mini-vac” is the best control of the individual flies that are currently present.
Brad @ Work says:
If this is not successful an aerosol like CB-80 pryethrum contact aerosol can be used. Spray lightly and repeat spray as needed.
An alternate would be electronic fly traps such as:
COMMERCIAL FLY TRAP-FT 30
INSECTALITE 18 WATT PROFESSIONAL FLY TRAP and the INSECTALITE 30 WATT PROFESSIONAL FLY TRAP
Brad @ Work says:
Late August and early September are the times to use a good residual spray like Suspend or Demon WP,spraying the outside walls of the building where cluster flies are likely to land and rest before entering the building.
These residual insecticides are applied outdoors to window frames, door frames, soffits and eaves as well as any other areas that are vulnerable to entry.
Brad @ Work says:
Application of to the surrounding soil may also help minimize Cluster Fly populations and later entry.
Recommended also would be a dust like Delta Dust, dusted into cracks that have not been sealed, allowing the dust to flow back into the void areas.Thoroughly caulking all exterior cracks on the sun-exposed sides (south and west) is very important.
So right now, there’s nothing we can do to get rid of them since they’re all adults. We’re going to try preventing it from happening again by putting insecticides outside, though…
