The cluster fly is a common fly that prefers to live outdoors. They commonly invade homes
during colder months seeking warmth. Cluster flies will cluster and swarm together inside
your home as temperatures drop, so it’s important to perform proper cluster fly control.

For proper control, you need to identify cluster fly activity. They are often mistaken for
other flies like house flies. They might look the same, but require different control techniques.
The cluster fly is typically around ⅜ of inch in length. They are usually light to
dark gray in color, with golden hairs covering their backs. When at rest, their wings overlap.
During Fall and Winter months, they can be found hibernating in attics, storage rooms,
or in wall voids. When Spring rolls around and temperatures rise, the cluster flies emerge
and cluster together around windows or other exit points.
To get control, first use Reclaim IT outside. This is a liquid insecticide that will repel
and kill any cluster flies around your home. Reclaim can also be used to treat a wide variety
of pests. Mix this with water in a pump sprayer, following label directions. Apply this outdoors
around windows, doors, eaves, and other entry points. This will create a protective barrier
that will keep cluster flies out come Fall.
Cluster flies do move slowly, so if you already have some inside, they can easily be swatted
or vacuumed up. You can also use Pyrid aerosol. This is a
pyrethrin aerosol that provides quick contact kills. Pyrid is also great for eliminating
many other pests.
You can also use D-Fense Dust. This is a waterproof insecticidal dust that is great to use for
hard to reach areas where cluster flies might be hiding. Use this with a duster and treat
under baseboards, behind electrical outlets, in attics, and in entry points.
You might also consider using a Mantis fly light trap. This is a light weight, ready
to use fly light that uses two, bright UV lights to attract flies. This fly light does
not zap the flies, but instead lures them to a glue board positioned behind the bulbs
where they will get stuck and unable to fly away.
Finally, prevent cluster flies from returning by frequently treating around your home with
Reclaim IT and D-Fense Dust, especially at the end of summer or early fall before temperatures
drop. And be sure to seal any voids and entry points.
