A house fly problem can be frustrating, but an infestation of the pesky cluster fly can be problematic to a much larger extent. Here at Key West Pest Control, cluster flies are a pest we face regularly during the cooler months.

Chances are, if you spot any number of cluster flies around the house, there are many more lurking.

Attracted to light, they spend the daytime clustering (as their name would suggest) in huge numbers, around the windows, doors, and even the sunny, south east-facing walls of our homes.

A particularly stubborn species of fly, these pests release a pheromone, calling to others to join the cluster, widening the scale of the infestation.

Our warm and sheltered homes have become the new, hot, hibernation destination of these squatting flies, replacing the hollow trees and other naturally sheltered areas in our surrounding environment which they historically preferred.

As the temperate drops in the evening, they retreat to our loft spaces, wall voids, crevices and eaves, seeking warm, undisturbed areas.

It’s the central heating in our homes, that tricks these hibernating pests into thinking that spring is here, prompting them to infest our living quarters.

Whilst cluster flies don’t pose a health risk to your family, these non-biting insects are unsightly and certainly a nuisance. Capable of damaging the aesthetic appeal of your home, cluster flies leave black spots of excrement on walls and windows that even considerable amounts of elbow grease can fall short of cleaning.

While the adults will leave in the summer to lay their eggs in soil, their young will emerge as fully-grown adults, flying straight back to the homes they can gain access to, to hibernate for the winter.

For homeowners tormented by buzzing clouds of cluster flies, in order to reinstate the pest-free equilibrium of your home, you’ll need the help of pest control professionals like Key West

Cluster flies? Argh! How do I keep them out of the house?

The first rules of Pest Control, according to Key West, are the two P’s; prevention and protection.

In the autumn months, before the cluster flies’ winter hibernation period begins, strap on your tool belt; it’s time to protect and seal your home.

Before you begin, it’s important to inspect your loft space, if a nasty surprise awaits and an infestation has formed, pest control professionals will need to be called. Sealing up an infestation can only create bigger problems, attracting much larger, more dangerous and more stubborn pests to treat.

If your loft is clear of cluster flies, begin to seal any possible entry to loft spaces, eaves, wall spaces, roof voids, ceiling spaces and any gaps and crevices around doors and windows. Go back to your soil and hollow trees you little nasties!

Long-lasting surface insecticides and DIY, store-bought options should be applied around doorways, windows, gaps around pipes and cables and where the sealing of loft spaces and the other areas detailed above isn’t possible.

If one or two cluster flies are uncovered across your home, ensure they’re killed, collected, securely bagged, and placed in an outside bin. The pheromone released by these flies continues to function long after death, do this, and you should avoid the cluster this pheromone will lead to your home.

Store-bought sprays can also be applied to the outside walls of the home where cluster flies will land, as they seek entry into your home. You may also wish to invest in a DIY soil treatment, to cut the cluster flies off at their source, where they breed and where their young become adults. Minimise their numbers.

To deter them from the light and warmth your home can offer, draw curtains where possible, and keep doors and windows (without fly screens) closed. Give them no excuse to target your home.

What are the signs of an infestation of cluster flies in my home?

To spot the signs of this pest in our homes it’s important to know how to identify these buzzing little blighters.

Easily mistaken for the common house fly, these clustering pests are large, black and only uniquely identifiable by the golden hairs that line the thorax and the chequered pattern on their abdomen. Sluggish in flight, their wings overlap when they’re resting.

Also keep an eye out for the previously mentioned stubborn, dark spots of excrement that cluster flies leave around the windows, doors, and south-east facing walls they favour.

The discovery of a small number of lame or dead cluster flies is another tell-tale sign of an infestation across the home.

They’re already here – How do I get them out of the house?

If an infestation has already established itself in your home, you’re going to need the experience of, and tools only available to, pest control professionals.

The trick with cluster flies, is to protect the home before their winter hibernation. Once they’re inside, their numbers are too high to control alone, and without effective solutions.
