How to Keep Flies Out of Your Home

Flies are not only annoying but can also be a carrier of diseases. Therefore, it is essential to keep them from entering your house.

In this article, well discuss how flies get into your house, the entry points for flies, the sources of attraction for them, and preventive measures to keep them from entering your house.

Understanding how flies get into your house

To keep flies out of your house, it is essential to understand how they get in. Flies are attracted to warm temperatures, food, and water, so any area in your house that provides these elements can attract flies.

Sources of attraction for flies

Warm temperatures: Flies thrive in warm temperatures, so they will be attracted to areas of your house that are warm, such as the kitchen, living room, and bathroom. Food: Flies are attracted to any source of food, including leftovers, fruits, and vegetables, and pet food.

If you leave these items uncovered, you will attract flies to your house. Water: Flies are also attracted to areas with water, such as drains, sinks, and pet water bowls.

Entry Points for flies

Flies can enter your house through various entry points, which includes:

Open windows: Flies can easily enter your house through open windows, especially if there are no screens. Unscreened doors: If your doors don’t have screens, flies can quickly enter your house.

Specific scenarios where flies can enter your house

Flies are common pests that can enter your home in several ways. Knowing where they are likely to come from can help you take preventative measures and keep your home free of these pests.

Flies attracted to water features

Swimming pools, ponds, fountains, and other water features that you have in your backyard can attract flies. These areas are where flies can lay their eggs, and also they can drink from the water source.

To prevent flies from entering your home from these water features, you can take several steps. For swimming pools, make sure that you cover them when not in use and use appropriate chemicals to keep the water clean.

If you have a pond or fountain in your yard, consider installing a pump to keep water moving and prevent it from becoming stagnant.

Flies in attics and crawl spaces

Flies can also enter your home through the vents in your attic or crawl space. They can find their way through any unsealed cracks in these areas and enter your home.

Moreover, if there are other pests in your attic, such as rodents, they can attract flies. To prevent flies from entering your home through your attic or crawl space, you can install screens on the vents to block their entry as well as seal any cracks through which they might enter.

Hire a professional to inspect and seal all potential entry points for pests as a preventative measure for future fly invasions.

Flies from messy garages

Garbage cans, debris, and stored items in garages can create a breeding ground for flies. Any food scraps, old containers, and other detritus you may have stored can attract flies.

To keep flies from entering your home through your garage, take measures to keep your garage clean and tidy. Keep your garbage cans properly sealed and empty them regularly.

Store your items properly in containers, to eliminate any potential breeding grounds for non-pest insects as well.

Flies potentially brought in through outdoor plants

Outdoor plants, including their clippings, can bring in flies. Flies are attracted to the moisture and nutrients in plant tissues and debris.

To prevent flies from entering your home through your outdoor plants, make sure your plants receive appropriate attention and care. Water your plants only as needed and maintain proper fertilization.

Ensure that any clippings or debris from pruning or watering removed from the plant area have been properly disposed of to avoid attracting flies or other pests.

Flies from pet mess

Dogs and cats can attract flies because of their poop and urine, which can attract them into the home. Flies are likely to enter your home through your doggie doors or any gaps in your attic or garage.

To prevent flies from entering your home through your pets’ messes, clean up after your pets regularly. Also, you can install a screen or door flap on your doggie doors to keep out flies and other insects.

Seal all potential entry points that lead from your home to attic, garage, or crawlspaces to keep unwanted pests out.

Solutions to removing flies from your house

If you already have a fly infestation in your home, there are several solutions you can use to get rid of the flies.

Professional pest control services

Hiring a professional to inspect and maintain your home regularly is the best course of action for keeping your home safe from infestations. Regular maintenance will ensure no entry points remain open, along with the opportunity to employ preventative measures to keep future fly invasions from happening.

Natural solutions to repel flies

Essential oils can be very effective in repelling flies. Scents such as lavender, peppermint, eucalyptus, and pine can help repel flies.

Place these scents in areas where flies are most likely to congregate. You can also use scented candles, which can give off a strong scent that flies dislike.

However, natural solutions are not as persistent as treatments provided by professional services.

Creating a less attractive environment for flies

Keeping your home clean and tidy is one of the best ways to prevent flies from entering and staying in your home. Clearing away food scraps, crumbs, and other waste that can attract flies is a critical preventative measure.

Keeping countertops, floors, and surfaces clean and free of clutter can also help discourage flies from congregating in these areas.


Flies can enter your home through various sources, including water features, attics, garages, plants, and pet mess. Preventative measures can be taken to lessen the likelihood of fly invasions, as well as solutions for ridding them from your home should they be present.

Hiring a professional pest control service can provide you peace of mind, while at-home remedies such as essential oils and keeping your home less attractive to flies can contribute to a more fly-free environment.

Additional Information About Flies

Flies are one of the most reviled invertebrate species that cause annoyance and potential health issues for homeowners. In this section, we will dive deeper into the biology and behavior of flies, research studies on fly control, and differentiating flies from other invertebrates.

Biology and behavior of flies

Flies are a diverse group of insects classified under the order Diptera. They have a wide range of sizes, shapes, and colors, with some species being only a few millimeters long while others may grow up to several centimeters.

Fly lifespan varies depending on the species and environmental conditions. Most flies live for one to two months, although some can live up to a year.

During their lifespan, flies spend most of their time searching for food and sources of water. They have a strong sense of smell, which aids them in locating potential food sources.

Flies are also known for their ability to transport pathogens, bacterias, and other microorganisms. They are capable of spreading several diseases, including cholera, typhoid fever, dysentery, and salmonella.

Their ability to carry and transmit diseases is what makes them a potential health hazard.

Research studies on fly control

Scientists have undertaken extensive research studies to understand the behavior of flies and develop effective control strategies. One area of study has focused on insecticidal properties of various chemical compounds and their lethal effects on the insect.

Pharmaceutical companies, among other industries, have produced insecticides to help control fly populations. Innovations in the development of more selective chemical treatments may help reduce environmental harm caused by unsystemic spraying of surroundings.

Moreover, genetic inheritance studies have also been conducted to better understand the morphology, physiology, and behavior of flies. This understanding provides insight into how best to develop targeted and selective treatments.

Differentiating flies from other invertebrates

Flies are often confused with similar-looking insects, such as beetles or true bugs. One key characteristic of flies is their anatomy.

Flies only have one pair of wings, which sets them apart from beetles, which have two pairs of wings. Also, flies have distinctive mouthparts that are modified for sucking, whereas beetles and other insects use their mandibles to bite and chew.

Another distinguishing characteristic is their long, thin legs. The combination of their wings, mouthparts, and leg structure gives them the ability to fly efficiently and makes their movement easy to distinguish.


Flies, like other invertebrates, are a critical part of any ecosystem. It is also important to remember that they can be a pesky nuisance to homes and businesses.

Understanding their biology, behavior, and control measures are critical to developing effective means to combat potential invasions. Scientific advancements in fly control treatments, such as studies of genetic inheritance and targeted insecticidal properties, can help offer alternatives to traditional means of pest control.

Proper identification of flies in comparison to other insects, and paying attention to the anatomy of these species, can ensure that homeowners are taking the best prevention measures possible. In conclusion, understanding and preventing flies from entering your home can greatly benefit your household’s health and hygiene.

Identifying typical entry points, reducing potential food and water sources, and applying preventive measures such as screening windows and doors or using fly-catching tools can be used to help avoid future infestations. For existing infestations, measures such as natural repellents or professional pest services can help decrease the fly population in your home.

This paired with a more in-depth understanding of the biology of flies and scientific research studies to develop different forms of control options, can help mitigate pest infestations within your home and promote a healthier environment for you and your family.
