Sometimes it takes no more than the furnace to be turned on and thoroughly _ the inside of the structure to start activity

-
CLUSTER FLY - FIELD GUIDE
Once stimulated, cluster flies seek light.
Light
-
CLUSTER FLY - FIELD GUIDE
they usually come out around loose- fitting wall switches and outlets, ceiling fixtures, window and door frames, window pulleys, etc =
to seek light
-
CLUSTER FLY - FIELD GUIDE
Cluster flies can usually be found at windows crawling on the
panes or frames, or around lamps or lights.

CLUSTER FLY - FIELD GUIDE
They are _ in their movements in comparison to house flies.
Sluggish
-
CLUSTER FLY - FIELD GUIDE
They usually give off a _ _ odor and leave a greasy spot when crushed.
Buckwheat honey

CLUSTER FLY - FIELD GUIDE
No attempt should be made to kill these insects in wall voids because the bodies of dead insects attract
dermestid beetles

CLUSTER FLY - FIELD GUIDE
wait until _ when all live over-wintering adults are out of the wall voids.

-
CLUSTER FLY - FIELD GUIDE
temporary relief is possible by using a vacuum and/or space sprays, and carefully
sealing interior entrances such as cracks around window frames.
-
CLUSTER FLY - FIELD GUIDE
Control begins _.
Outside
-
CLUSTER FLY - FIELD GUIDE
Reducing outside population is impractical since
their larvae breed in earthworms.
-
CLUSTER FLY - FIELD GUIDE
use of _ is recommended.
preventative physical and chemical barriers
-
CLUSTER FLY - FIELD GUIDE
All vents (roof, overhang, weepholes, etc.) should be screened with at least NUMBER-mesh screening.
16 mesh
-
CLUSTER FLY - FIELD GUIDE
Caulk around cable entrances, windows, doors, and overhangs. These steps should be taken in MONTHS
June or July
-
CLUSTER FLY - FIELD GUIDE
Preventative chemical barriers =
applying a highly repellent, long-lasting residual to all outside vertical walls and the adjacent overhang;
-
CLUSTER FLY - FIELD GUIDE
formulations work best.
microencapsulated pyrethroids or pyrethrins, or pyrethroid wettable powder
-
CLUSTER FLY - FIELD GUIDE
Exterior pesticide application is made just before the
last seasonal generation of adults emerge
-
CLUSTER FLY - FIELD GUIDE
If adults have already begun to congregate and attempt entry into buildings,
it may be too late for preventative action.
-
CLUSTER FLY - FIELD GUIDE
The best solution is physical removal with a good shop-type vacuum. Then treat the
vertical walls
-
CLUSTER FLY - FIELD GUIDE
Temporary but immediate indoor relief can be achieved by
removal with a vacuum or by using space sprays in individual rooms.
-
CLUSTER FLY - FIELD GUIDE
To prevent entry of more flies, seal the possible routes of entry... use
Use silicone caulk and/or foam to seal.
-
CLUSTER FLY - FIELD GUIDE
If cluster flies are in a false ceiling, the population can be reduced by
an electrocutor insect light trap (ILT)
-
CLUSTER FLY - FIELD GUIDE
If cluster flies are in a false ceiling, install a continuously burning 60-watt bulb which attracts the flies, causes them to exhaust their stored food, and die right around the light; be sure to remove them with a vacuum.

CLUSTER FLY - FIELD GUIDE
Use old fashioned fly strips, glue boards, or other sticky surfaces that may be suspended from the uppermost surface of the false ceiling void near the _.

CLUSTER FLY - FIELD GUIDE
To reduce the number of flies coming into a room from a false ceiling, seal all cracks through which light enters. Use _
duct tape or caulk.
