Cluster Fly Control
The cost to spray cluster flies can differ by a lot for each pest control company. Our price
ran around $175.00 for a small house and as much as $300.00 for a large home. Prevention is always the best control and will
probably save you some money.
The first and most important step in cluster Fly elimination is to seal or eliminate all possible entry points using caulk
or wire mesh to seal all cracks and crevices. Doors, (including garage door) and windows should never be left open unless
they are screened.
2. The key to preventing cluster flies is to use a good residual (lasting
three months) surface spray such as the one listed below. It should be sprayed on all areas of the exterior of your
house where cluster flies enter such as cracks in your siding,eaves, overhangs, and around windows and doors. This should
be done from mid August to mid September where cluster flies congregate, hibernate or enter a structure. A power sprayer works
best and is the fastest spraying method, but a hand pump sprayer will also work. Most flies will be seen entering small openings
of your siding on the sunny sides of your house. You may notice tiny brown fly spots in areas where flies are entering.
If flies have already gotten into your home setting off fly bombs may help. Be sure to bomb the attic. A thin line of residual
insecticide may also be sprayed on your window sills to kill the flies that are clustering around that area. Be sure to follow
insecticide directions carefully.
hibernating in the warmth of your home you will notice most fly activity on sunny days. When spring arrives cluster flies
in your walls and attic will resume their normal activity and try to exit you home with the attentions of laying eggs in the
grassy areas of your property. This is also a good time to spray the outside of your house.

Cluster flies hatch out of fertile areas where earthworms are prevalent such as large lawns. They can
hatch out 3 or 4 generations per summer.
Female cluster flies lay eggs in your lawn in the vicinity of the earthworm. Eggs hatch in three days and the larvae penetrate
and develop in the bodies of earthworms. This larval stage lasts 13 to 22 days, and the pupal stage, 11 to 14. The life cycle
is completed in 27 to 39 days. There are about four generations during the summer. Populations vary from year to year, sometimes
worse after wet summers.Most likely if you have a large yard and live in a rural area you will have problems with cluster

shorten in mid-August through October. Flies cluster on the warm sides of buildings in late summer during the day. This is

be completed in about two weeks during warm weather. House flies breed in a variety of organic materials
such as manure, garbage, sewage, food wastes, lawn clippings, septic tanks and silage. In warmer climates they breed
throughout the year. In most areas they overwinter as a fly larvae or pupae under manure piles or other
breeding areas that attracts them.
In milk barns, hog houses, or confined feeding units that are closed and warm, flies may continue to develop during

Answer To Cluster Flies in Lawn
I don't think that treating your lawn for cluster flies would help because in most cases the flies are coming from neighboring
properties. They usually hatch out of fertile areas where earthworms are prevelent such as large lawns. Cluster flies can
hatch out 3 or 4 generations per summer. As far as I know there isn't any insecticide that is labeled for spraying cluster
flies in a yard.
