Cluster flies, known for their sluggish demeanor and tendency to congregate in large groups, can quickly become a nuisance in outdoor environments, especially during warmer months. Whether they’re infiltrating your patio, garden, or backyard, their presence can turn an enjoyable outdoor experience into a constant struggle against swarms of unwelcome guests. But fear not – with the right strategies and natural remedies, you can regain control of your outdoor space and bid farewell to cluster flies for good.

How to Identify Cluster Flies

Identifying cluster flies is crucial in effectively managing infestations. These flies resemble common houseflies but are typically larger and slower in movement. They often gather in clusters on surfaces such as windows, walls, and ceilings, particularly in sunny areas. Additionally, cluster flies have distinct golden hairs on their thorax, which differentiate them from other fly species.

To further confirm their presence, observe their behavior – cluster flies tend to seek warmth indoors during cooler months and may congregate around light sources. Regular inspections of potential entry points, such as gaps around windows and doors, can also aid in identification. By familiarizing yourself with the characteristics and habits of cluster flies, you can take proactive measures to prevent and control infestations effectively.

Spray an Approved Indoor Pesticide

When combating cluster flies indoors, using an approved indoor pesticide can be an effective solution. Opt for pesticides specifically formulated for flying insects and labeled safe for indoor use. Thoroughly spray infested areas such as window sills, door frames, and other entry points. Ensure proper ventilation during application and follow manufacturer instructions carefully to maximize effectiveness while minimizing risks to pets and humans.

Seal Interior Cracks and Gaps

Preventing cluster flies from entering your home starts with sealing interior cracks and gaps. Inspect walls, windows, doors, and utility penetrations for any openings that may serve as entry points for flies. Use caulking or weather-stripping to seal these gaps effectively and prevent further infestations. By addressing potential entryways, you can create a barrier that limits the access of cluster flies to your indoor spaces.

Apply Pesticide Dust behind Your Walls

For persistent cluster fly infestations, applying pesticide dust behind walls can provide long-lasting control. Utilize a hand duster to distribute the pesticide dust evenly in voids and spaces behind walls where flies may hide or breed. This method targets flies at their source, disrupting their lifecycle and preventing future infestations.

Exercise caution when handling and applying pesticide dust, following safety guidelines to minimize risks to yourself and others. With strategic application, pesticide dust can be a valuable tool in your battle against cluster flies indoors.

Make a Homemade Vinegar Fly Trap

Crafting a homemade vinegar fly trap is a simple yet effective way to combat cluster flies. Start by filling a shallow dish with apple cider vinegar – the strong scent attracts flies, drawing them towards the trap. Add a few drops of dish soap to break the surface tension, causing flies to drown upon contact.

Place the vinegar trap in areas where cluster flies are prevalent, such as near windows or entryways. Regularly empty and refill the trap to maintain its efficacy. With this DIY solution, you can significantly reduce the population of cluster flies in your home without resorting to harsh chemicals.

Vacuum Cleaner

Using a vacuum cleaner is a practical method for removing cluster flies from indoor spaces. Equip your vacuum with a nozzle attachment to reach crevices and tight spaces where flies may hide. Simply vacuum up any visible flies, ensuring to dispose of the vacuum bag or empty the canister promptly to prevent flies from escaping.

Vacuuming not only eliminates adult flies but also removes eggs and larvae, helping to interrupt the fly lifecycle and prevent future infestations. Regular vacuuming, especially in areas prone to cluster fly activity, can significantly reduce their numbers and keep your home fly-free

Cluster Flies vs. House Flies

Understanding the differences between cluster flies and house flies is essential for effective pest management. While both species share similar appearances, cluster flies are larger and slower-moving than house flies. Cluster flies also tend to congregate in groups, often seeking warmth indoors during cooler months.

In contrast, house flies are more agile and active, frequently buzzing around food sources and waste. Additionally, cluster flies have distinct golden hairs on their thorax, while house flies lack this feature. By recognizing these distinctions, you can tailor your pest control strategies to target the specific behaviors and preferences of each fly species, improving your chances of successful eradication.

Light Traps

Light traps are an effective tool for capturing cluster flies indoors. These devices utilize ultraviolet light to attract flies, luring them into a trap where they become trapped and unable to escape. Place light traps in areas where cluster flies are commonly found, such as near windows or light fixtures. Regularly clean and empty the traps to maintain their effectiveness.

Light traps offer a non-toxic and chemical-free method of controlling cluster fly populations indoors, making them an environmentally friendly option for pest management.


Vinegar is a versatile and natural solution for repelling cluster flies. The strong odor of vinegar acts as a deterrent, discouraging flies from entering treated areas. Create a vinegar spray by mixing equal parts vinegar and water in a spray bottle and apply it to surfaces where flies are present. Additionally, setting out bowls of vinegar can attract and trap flies, effectively reducing their numbers.

Vinegar is safe to use around pets and children, making it a popular choice for eco-conscious homeowners seeking non-toxic pest control methods.

Diatomaceous Earth

Diatomaceous earth is a natural and non-toxic substance derived from fossilized algae. It is commonly used as a pesticide for controlling various pests, including cluster flies. Diatomaceous earth works by absorbing the oils and fats from the outer layer of insects, causing them to dehydrate and die. Apply diatomaceous earth in areas where cluster flies are active, such as entry points and hiding spots.

Be sure to use food-grade diatomaceous earth, which is safe for use around humans and pets. With regular application, diatomaceous earth can effectively reduce cluster fly populations without the need for harsh chemicals or pesticides.

What are the Risks/Diseases of Cluster Flies?

While cluster flies are primarily a nuisance pest, they can pose certain risks to human health. These flies do not bite or sting, but their presence in large numbers can trigger allergies and asthma symptoms in sensitive individuals. Additionally, cluster flies have been known to carry and spread bacteria and pathogens, potentially contaminating surfaces and food sources in homes.

To mitigate these risks, it is essential to promptly address cluster fly infestations and implement effective pest control measures. By understanding the potential health hazards associated with cluster flies, homeowners can take proactive steps to protect themselves and their families from harm.

Battling Cluster Flies Naturally

To tackle cluster flies head-on, start by identifying their entry points and breeding grounds. Seal cracks, gaps, and openings around windows, doors, and vents to prevent their infiltration. Additionally, DE cluttering and maintaining cleanliness in outdoor spaces can deter flies from settling in.

Now, let’s delve into the magic of vinegar – a natural enemy of cluster flies. Simply mix equal parts vinegar and water in a spray bottle and liberally apply it to fly-infested areas. The acidic scent repels flies without harming plants or pets, making it a safe and eco-friendly option.

But wait, there’s more! Other natural remedies like essential oils can also work wonders in warding off cluster flies. Peppermint, eucalyptus, and citronella oils emit fragrances that flies despise, effectively keeping them at bay.
