Cluster fly control is the inspection, sealing and cleanup of an older farmhouse where cluster flies gather and later show up indoors. The technician looks at the attic, the wall voids and the outside of the house to find where the flies are getting in, then closes those openings. The plan is built on what the building shows.
Cluster flies are slow, sluggish flies that often turn up in the upper rooms of older farmhouses in the cooler months. They can be a steady nuisance in a house with an attic and wall voids, but they are a nuisance rather than a biting pest. The houses around Montpelier that tend to get them are the older farmhouses, many with attics, wall voids and gaps where the siding meets the frame. That is the setting this page is written for.
The work in a farmhouse with cluster flies is the same kind of work as for other autumn invaders: find the openings, close them, and clear what is already inside. The plan starts in the attic and the wall voids, because that is where the flies are most often found, and then moves to the outside of the house. A technician does not open walls or insulation without a reason, and the openings are chosen by what the inspection finds.
Cluster flies are often confused with boxelder bugs and house flies, and the work for each is different. Boxelder bugs have their own page, Boxelder Bug Control, which covers the sealing and the warm-day return. For the rodent openings that let other pests in as well, see Rodent Exclusion and Sealing, and for the seasonal plan that ties these together, see General Pest Control.
Do not fog or spray an attic or wall void, because the product can settle where people, pets and wiring are. Do not climb into a low or dark attic alone, and watch for loose insulation and exposed nails. Do not open a wall to chase flies, since you can disturb wiring or insulation. Empty vacuum bags and canisters outdoors. A technician plans any opening and any product use on site.
The technician identifies the flies on site, since a sluggish fly in a sunny room or an attic can be one of several kinds. The identification decides which openings matter and which control is useful. A sample is checked before anything is planned.
The attic, the upper rooms and the wall spaces that are accessible are checked for flies, droppings and dead insects. The technician notes where the flies collect and which rooms are most affected. Walls are not opened without a reason, and insulation is moved only where the inspection needs it.
The outside of the house is checked for gaps at the siding, the frame, the soffits, the attic vents and the window frames. The technician notes which gaps line up with the places where flies were found. This is the step that finds the way in.
Gaps are closed with materials suited to each opening. Vents are screened rather than blocked, and window and door frames are sealed where they meet the wall. The repairs are finished before the cooler months where possible, so the house is less likely to collect new flies.
Flies already inside are removed by vacuum, and the technician advises on how to empty the vacuum outdoors. The next visit is set for when a technician is free, and it checks for new flies and for any opening that has not been closed.
A technician identifies the insect on site. Sluggish flies that collect in a sunny room or an attic can point toward cluster flies, but a closer look is needed to be sure.
Other flies are quicker and tend to gather around food, garbage or drains, while the sluggish flies in an upper room are often seen near windows or ceilings. The technician checks the insect before deciding on the work.
Identification matters because the openings and the cleanup depend on the insect. A boxelder bug, a house fly and a cluster fly can all be found in the same farmhouse, and each one is handled on its own terms.
They are most often found in the attic, in wall voids and in the upper rooms of older farmhouses, where the building holds heat and the flies gather.
The attic is usually the first place to look, because it is warm, sheltered and often has gaps at the eaves and vents. Upper rooms next to the attic or the outside walls are often where the flies are seen first.
Wall voids are harder to reach, and the technician looks at the gaps that lead into them rather than opening the wall. The aim is to find the way in, not to chase each fly to its last hiding place.
The inspection looks at gaps where the siding meets the frame, around windows, at vent openings and the attic access, and at the cracks in the foundation that let other insects in too.
The siding and frame joints are the most common gaps on older farmhouses, because the boards have moved and the trim has pulled away over the years. A technician checks each joint on the sunny sides first and then the others.
Vents and the attic access are sealed or screened so that air still moves through them. Window frames and the foundation are checked where they meet the wall, since those joints let in other pests too.
Yes, a vacuum can remove flies that are already inside. It does not close the way in, so the work is not finished until the openings are repaired.
A vacuum is a quick way to clear the flies from a window or ceiling. The bag or canister should be emptied outdoors so the flies do not come back into the house.
The technician advises on both steps: the cleanup inside and the repairs outside. Doing only the cleanup tends to leave the route open for the next group.
The size of the house, how many rooms, attics and wall areas are involved, how many openings need sealing and whether follow-up visits are needed all change the price. The price is explained and approved before work starts.
A small house with one attic and a few gaps is a short job. A large farmhouse with several attic spaces, many window frames and siding on every side takes longer, and the time spent reaching each opening shows up in the price.
Insulation that has to be moved, or a wall that has to be opened, adds time and is priced separately. No figure is given in advance, and no work starts until the homeowner has seen the price and agreed to it.
Older farmhouses with a large attic and little insulation tend to collect flies in the upper rooms. The work centers on the attic and the gaps at the eaves, the vents and the attic access. The repairs are usually done from the outside and the attic, and the upper rooms are cleared last.
When flies collect in wall voids, the technician looks for the gap that lets them in, often at the siding, a window frame or a utility line. Opening the wall is not the first step. The repair is made at the gap, and the cleanup inside is limited to what can be reached without damaging the wall.
Some farmhouses have cluster flies and boxelder bugs in the same rooms, and both come through the same gaps under the siding and around the frames. The plan covers the shared openings first, then deals with each insect on its own terms.
Old farmhouses on the section roads around Montpelier are the buildings where cluster flies are most often mentioned. Many have large attics, wood siding and gaps at the frame, and those features shape the work. The attic is checked before the walls, and the outbuildings are checked for the same kinds of gaps.
Gas and oil boom houses in the town core of Montpelier, Dunkirk, Redkey, Eaton and Albany often have attics and older frame walls. The sealing there focuses on the siding joints and the vents, since those are the openings most often found on houses of that age.
Large farmhouses in the Geneva area and around Berne are part of the same pattern, with large attics and older frames. The work is the same, and the plan is set by the building in front of the technician.
Most cluster fly control calls are scheduled the same day when a technician is free, and you approve the price before any work starts.

Boxelder bugs and brown marmorated stink bugs are the fall invaders that Purdue University Extension material names for Indiana.
They are a nuisance rather than a biting pest. Their numbers in an attic or upper room are what make them a problem for homeowners. The work is finding the openings they use and closing them.

Upper rooms and the attic are often warm and sheltered, and they sit next to the gaps at the eaves and vents. The technician checks those gaps first, since they are where flies tend to get in.
Usually not. The technician finds the way in from the attic and the outside, and opens a wall only if the inspection needs it. Opening a wall can disturb wiring and insulation, so it is kept to a minimum.
The sealing overlaps, because both insects get in through the siding and frame joints. The cleanup and the timing differ, and the technician handles each one on its own terms. A separate page covers boxelder bugs in more detail.
Sealing reduces the routes into the house and tends to lower the numbers that collect. A technician cannot promise a result, but the openings found on the inspection are the ones that matter most.
The price is set after the inspection and explained on site. It depends on the house size, the attic and wall areas, the number of openings and the number of visits. The homeowner approves it before any work starts.
