How to Get Rid of Flies in Your House?

If there’s one thing that’ll have you questioning your sanity in the warmer months, it’s the constant buzz of flies. They swoop in like they own the place, and before you know it, they’ve made themselves right at home — usually in the kitchen, where you least want them. I know this all too well. Growing up in Melbourne, I’ve had my fair share of battles with flies, from the backyard BBQs turned into fly conventions to those moments when you’re just trying to enjoy a quiet meal. And it’s not just about the inconvenience. Knowing how to get rid of flies is crucial, as they can carry harmful bacteria, turning your home into a health risk zone.

But don’t worry, this isn’t a hopeless situation. With the right strategies, you can take control of your home and say goodbye to flies for good. Whether you’re tackling a sudden infestation or just trying to keep your home fly-free, this guide is packed with real solutions — from natural fly repellents to the best DIY traps that actually work. Let’s dive in and reclaim your space from these buzzing pests.

Why Getting Rid of Flies is Crucial

When you think of flies, you probably imagine them buzzing around food, landing on your kitchen counters, or making a nuisance of themselves while you’re enjoying a meal. But here’s the kicker: flies are actually carriers of disease. Over the years, I’ve come across numerous stories from friends and clients dealing with fly-related issues. From food poisoning after flies landed on food to the spread of infections from the tiniest overlooked fly in the kitchen, it’s clear that flies can do more than ruin a BBQ.

Flies spread bacteria through their saliva, excrement, and even by regurgitating food they’ve previously eaten. This can result in the spread of serious diseases like Salmonella, E. coli, and even Cholera. One particular time, I had a neighbour who suffered from gastrointestinal issues after a fly infestation in their kitchen. It wasn’t until they started to dig into where these flies had come from that they realised they were unintentionally bringing bacteria into their home.

Flies are also fast reproducers, and they don’t waste any time. A female fly can lay up to 500 eggs in her short lifetime, and if you don’t act fast, you can find yourself facing an infestation in just a few days. I remember a time when I went away for a weekend trip to the Mornington Peninsula, and upon returning, I found my home swarming with flies. Their life cycle can be as short as 7 days under ideal conditions, and let me tell you, that weekend trip felt like it had turned into a fly paradise by the time I got home. Preventing an infestation is all about swift action.

What Attracts Flies to Your Home? Identifying the Root Causes

Flies don’t just randomly appear in your house – they’re attracted to very specific things, and understanding what those are can help you tackle the problem. From food scraps to moisture in hidden corners of your home, here’s what brings them in:

• Decaying Organic Matter: It’s no secret that flies love food waste, and in my experience, keeping bins sealed and food packaging clean has made all the difference. Animal waste and compost heaps are also prime breeding grounds. I’ve had clients who lived near farms or had compost piles in their backyard, and they found that flies would breed around those areas and then make their way inside.
  
• Overripe/Rotting Fruits and Vegetables: Fruit flies, in particular, can be a real pain when they find their way into your home. I’ve had this happen at my own place when we left a few overripe peaches out on the kitchen counter. Within hours, the kitchen was buzzing.
  
• Moisture and Damp Areas: Dirty drains or standing water in places like the sink, bathtub, or garden can attract flies. I remember once, after a couple of rainy weeks, I discovered a breeding ground in a forgotten corner of my kitchen drain, and within days, I had flies.
  

How Flies Enter Your Home: Common Entry Points

While flies may be attracted to certain areas, they also know how to get inside. They’re not shy about finding cracks and openings in your home. Most homes have plenty of unsealed windows, doors, and even ventilation systems that act as entry points. In my experience, the kitchen tends to be a major hotspot. That’s why I always make sure my fly screens are intact, especially after a hot, dry spell in Melbourne, where flies seem to thrive.

How to Prevent Flies from Entering Your Home: The First Line of Defence

Sanitation Tips for Keeping Flies Out

There’s an old saying, “prevention is better than cure,” and when it comes to flies, this could not be truer. Keeping your home free of the things that attract flies is the most effective way to avoid an infestation.

Here’s a checklist that I personally follow and recommend to clients:

• Keep food areas clean: It’s simple, but wiping down countertops and cleaning up after meals is the best place to start. I’ve seen firsthand how quickly flies gather around a forgotten crumb.
  
• Proper waste management: Store garbage in sealed bins and empty them regularly. I’ve been guilty of letting a bin sit a little too long, only to find myself swarmed by flies later.
  
• Fix any moisture issues: Whether it’s a leaky tap or a damp drain, flies love these spots. I once had a drain issue in my bathroom that became a breeding ground, and once I took care of it, the problem was gone.
  

Seal All Entry Points (Exclusion)

Stopping flies from entering your home is key. Here are my tried-and-tested methods for keeping them out:

• Repair window and door screens: I make sure these are in top condition, especially during the warmer months when flies are more active.
  
• Seal cracks and holes: This one is often overlooked, but a small crack in your windowsill can be an invitation for flies to enter.
  
• Install pleated insect fly screens: I found these incredibly useful when living in Melbourne’s northern suburbs, where flies are more frequent. They allow airflow without inviting pests in.
  

Effective Fly Control: Natural and Homemade Remedies to Keep Your Home Fly-Free

Fly-Repellent Plants and Herbs

Over the years, I’ve found that the best way to deter flies naturally is to use what nature has already provided. Planting certain herbs and plants around your home can work wonders. The beauty of this method is that it not only keeps flies away but also enhances the ambience of your home. Here are some plants that have become staples in my garden and kitchen:

• Basil: Not only does basil add a fresh, earthy fragrance to your home, but it also acts as a natural fly repellent. I’ve kept a pot of basil on my kitchen windowsill for years, and it’s done wonders in keeping flies at bay, especially in summer when they’re most active.
  
• Bay Laurel: The bitter, aromatic smell of bay leaves is highly effective at repelling flies. In fact, I use dried bay leaves in some of my pantry drawers to ward off flies and other pests. It’s a simple and elegant solution that works well in both indoor and outdoor settings. Just a word of caution: bay leaves are toxic to dogs and cats if swallowed, so keep them out of reach of pets.
  
• Mint: Flies don’t like mint’s distinct, refreshing scent. I’ve got a pot of peppermint on my porch that not only looks great but helps keep flies away from the outdoor dining area
  
• Lavender: This classic scent isn’t just for relaxation—it’s also a fantastic fly deterrent. I’ve always had a few lavender sprigs in my kitchen, and it helps both with flies and the occasional mosquito that wanders inside.
  
• Rosemary: Another herb that flies dislike, rosemary works well as a deterrent when grown in pots or even as part of a garden. I’ve kept a few pots near entryways to discourage any flies from hanging around.
  

By planting these fly-repelling herbs near windows or doors, I’ve been able to reduce the number of flies getting in, and the bonus is that they also add a nice touch to my space.

DIY Fly Traps: Homemade Solutions for Fly Elimination

When you’ve got flies already buzzing around, there’s no time to waste. A homemade fly trap can be a life-saver, and I’ve tried a few over the years. Here are some of my favourite DIY traps that work like a charm:

• Apple Cider Vinegar and Dish Soap Traps: This is one of the easiest and most effective traps I’ve used. I’ve had success with apple cider vinegar, which flies find irresistible. Here’s how I set it up:
  
  1. Mix equal parts apple cider vinegar and water in a small bowl or jar.
     
  2. Add a couple of drops of dish soap (I use a fruity-scented one) to break the surface tension.
     
  3. Flies are drawn to the vinegar and, when they land, they get trapped by the soap.
     This method never fails me, and it’s a great way to trap flies without using any harsh chemicals. I place these traps near windows or food areas where flies tend to gather.
     
• Two-Litre Bottle Trap: Another tried-and-true method involves reusing an old plastic bottle. Here’s how it works:
  
  1. Cut off the top of a 2-litre plastic bottle to create a funnel shape.
     
  2. In the bottom, add a mixture of vinegar, dish soap, and sugar.
     
  3. Invert the cut-off top and place it into the bottle. The flies will be drawn in by the sweet smell and become trapped inside.
     I’ve used this method countless times, and it’s been especially effective in the kitchen, where the fruit flies seem to love hanging out.
     
• Rotting Fruit Trap: This one is perfect if you’ve got overripe fruit lying around. I’ve set up this trap more times than I can count, especially when I’ve forgotten about a fruit bowl on the kitchen counter:
  
  1. Place some rotting fruit (bananas work great) in a bowl or bag.
     
  2. Add a splash of white vinegar and a drop of dish soap to make the concoction irresistible.
     
  3. Poke small holes in the top of the bag and wait for the flies to be drawn in. They’ll get stuck in the sticky mixture.
     

I always make sure to place these traps away from living areas to avoid the smell becoming too overpowering. The rotting fruit trap has been particularly effective in the spring and summer months when fruit flies seem to appear out of nowhere.

Essential Oils and Natural Fly Deterrents

One thing I’ve always relied on for keeping flies at bay is essential oils. Not only do they smell fantastic, but they also serve as powerful natural repellents. Here’s how I’ve incorporated essential oils into my fly control routine:

• Peppermint Oil: Flies absolutely hate the smell of peppermint. I’ve made a quick peppermint oil spray by adding a few drops of oil to a spray bottle filled with water. It’s perfect for misting around windows, doors, or other fly-prone areas.
  
• Lavender Oil: Along with its calming effects, lavender is a great fly repellent. I’ve used it in a diffuser or mixed it with water in a spray bottle and applied it around the home.
  
• Lemongrass Oil: This one works wonders, especially during the warmer months. I’ve mixed lemongrass oil with water and a bit of rubbing alcohol for a natural fly repellent spray. The citrusy scent is refreshing and flies just don’t stand a chance.
  

A little goes a long way, and what I love about using essential oils is that it doesn’t just help with flies, but also makes the whole house smell lovely!

How to Trap and Kill Flies: Additional Solutions for a Fly-Free Home

Using Commercial Fly Traps and Fly Paper

When DIY methods aren’t enough, commercial fly traps are an excellent next step. I’ve found that they provide extra support when dealing with larger infestations or more persistent fly problems. There are a variety of traps out there, but I’ve personally found the following methods to be the most effective:

• UV Light Traps: These traps use ultraviolet (UV) light to attract flies, and I’ve had great success using them around my home. The light lures the flies in, and they get trapped in a glue board or a collection container. The best part? You don’t have to worry about chemicals, and they’re much cleaner than fly-killing sprays. I’ve placed these traps in areas where flies tend to hover, like near windows or doorways, and they’ve proven quite effective, especially during the warmer months when flies are most active.
  Pro Tip: Ensure you place your UV traps out of direct sunlight and away from competing light sources, so the flies are more attracted to them. I’ve made the mistake of having a bright lamp near the trap, which caused the flies to be drawn to it instead.
  
• Sticky Fly Paper (Fly Ribbons): Fly paper may seem old-fashioned, but it works. These sticky strips are covered in a special adhesive that captures flies when they land. I’ve used them in areas where flies tend to accumulate, such as near windows or near garbage bins. The one thing to be aware of is that they can get a bit messy. I try to place them in corners where they’re out of sight to avoid an eyesore in the middle of a room. They’re highly effective and non-toxic, making them safe around pets and children.
  

Quick Tip: If you’ve got pets running around, be cautious where you hang sticky fly paper. It’s all too easy for a playful dog to end up stuck to it! I’ve had to fish one out of a sticky situation once or twice.

Alternative Trap Methods for a DIY Approach

If you prefer a more hands-on approach, you can easily make your own fly traps at home. These traps can be a real game-changer if you’re dealing with a high volume of flies, and they’re both simple and cost-effective. Here are some alternatives I’ve used successfully:

• Syrup and Wine Trap: This one is especially effective because flies are drawn to the fermentation smell of wine. I usually set this trap in my kitchen:
  
  1. Take a bottle with some leftover wine.
     
  2. Add maple syrup or honey to the bottle to create a sweet scent.
     
  3. Place a paper funnel over the bottle neck (similar to the two-litre bottle trap method) and watch the flies get trapped.
     
• This trap is particularly handy when I have a leftover bottle of wine that’s been sitting around. Flies love the fermented scent, and the syrup adds the perfect touch to lure them in.
  
• Meat Scraps Trap: While not the most pleasant-smelling trap, this one is effective for attracting flies, especially when they’ve already made themselves at home in your garbage area or near decaying food.
  
  1. Take some rotten meat or fish scraps (I usually use cheap fish or leftover cooked meat).
     
  2. Place the scraps in a bowl or container with sugar or honey to make the trap more attractive.
     
  3. Cover the container with a plastic bag, poking small holes in it to let the flies enter.
     
• It’s definitely not the most pleasant of traps, but when the flies are drawn to the scent, they quickly get caught. If you’re sensitive to the smell, it’s best to set the trap away from living areas and let it work its magic.
  

When to Call in Professional Pest Control: Knowing When You Need Help

Despite all of these methods, there are times when the fly problem just won’t go away. If you’re dealing with an extensive fly infestation or one that seems to be breeding in hidden areas, it may be time to consider professional pest control.

Signs You Need Professional Help

• Persistent Infestation: If you’ve tried all the DIY solutions and the flies just keep coming back, a professional pest control service can assess the situation and treat it at every stage of the fly life cycle.
  
• Hidden Breeding Sites: Flies can breed in areas you might not even know about, such as wall voids, crawl spaces, or attic insulation. If you suspect this is the case, it’s best to call in the experts who have the equipment and knowledge to locate and eliminate these hidden breeding grounds.
  
• Severe Fly Problems: If you’re dealing with an infestation that’s beyond your control, it’s important to get the professionals involved. They can use specialised tools and treatments to target flies at every stage of their life, from egg to adult.
  

What to Expect from a Professional Pest Control Service

I’ve worked with pest control companies several times over the years, and here’s what I’ve learned. A good pest control service will:

1. Assess the Situation: They’ll inspect your home to identify entry points, breeding grounds, and problem areas.
   
2. Provide a Plan: After assessing the situation, they’ll provide a tailored treatment plan, which could include spraying, baiting, or using more advanced methods.
   
3. Treat and Prevent: They’ll not only deal with the current infestation but also work to prevent future problems by sealing entry points, treating breeding grounds, and offering advice on ongoing prevention.
   

In terms of cost, you’re looking at anywhere from $175 to $310 for a professional fly control service in Australia. It’s worth noting that in some rental properties, landlords are responsible for pest control, so if you’re renting, you might be able to get them to foot the bill.
