Cluster flies, often misidentified as house flies, are those really annoying flies that get inside in the fall and pester us through autumn, a bit in the winter, and come out in droves in the spring as it starts to warm up outside. They don't bite, but they buzz and buzz and buzz, then they land on your plate, then they buzz some more, then they're on your coffee cup, then back to buzzing around your face. They are ridiculously hard to swat because their hind wings are modified into halteres, a characteristic shared by all true flies to improve balance. There are 6 species of cluster fly, all with halteres that look like little white flaps behind the one set of wings. This basically makes them air ninjas who can avoid our hands or swatters, all the while laughing their buzzy little laugh. Did we mention they buzz?
Cluster flies parasitize earth worms as larvae, or maggots, and pupate in the soil. There are no earthworms native to Canada - ours were all wiped out about 13 000 years ago during the last ice age - so cluster flies provide an ecological service, when they are outside. When they are inside, they simply pester us.
Treating for cluster flies is easy. In late summer or early fall, we complete an interior and exterior treatment, focusing on the areas where they tend to gain access to the building. This prevents them from getting in, which offers relief through winter and spring. We can also treat in the spring if you read this too late for a fall treatment and they're already driving you crazy. This service starts around $185 plus HST and typically is guaranteed for 60 days.
We can treat for any type of fly, not just cluster flies.
