How to get rid of flies in roof air vents
If you've ever had flies buzzing around your home, you know how annoying they can be. But when they start sneaking in through your roof air vents, it’s a whole new level of frustration. One minute your house is peaceful, the next you’ve got a swarm of tiny intruders dive-bombing your dinner. So, let’s talk about how to get rid of these little pests before they turn your vents into a fly hotel.
Why are flies getting into my roof air vents?
Flies, like all unwelcome guests, are opportunists. They love dark, cozy spaces, and if your roof air vents are open or don’t have proper mesh, they’ll see it as an invitation. Many standard vents, especially the old mushroom-style ones, don’t come with proper pest guards or ember mesh, making them the perfect entry point for flies, mosquitoes, and even the occasional adventurous cockroach. Once inside, they can find their way down into your home through rangehoods or bathroom exhaust fans.
How to stop flies from using your roof air vents as a doorway
1. Install a vent with built-in pest protection
This is the easiest and most effective solution. Dragon Vents Australia has designed a range of vents that come with enclosed mesh to stop flies, insects, and even embers during bushfire season. If your vent has gaps or is just an open pathway to your home, it’s time for an upgrade. The Dragon Vent range is made to fit all 150mm outlet rangehoods, and for other sizes like 120mm or 200mm, you can use a y-piece adaptor to keep that maximum airflow. Flies won’t stand a chance.
2. Check for existing gaps and seal them
Flies are small, sneaky, and determined. If your roof air vents have any small cracks or open sections around them, it’s basically an all-you-can-eat buffet invitation. Use silicone sealant or weatherproof tape to close up any openings they might be using.
3. Clean your vents regularly
Ever wondered why flies seem to love certain areas of your home? It’s usually because they’ve found something they like – food, moisture, or a nice little hiding spot. Dust, grease, and debris can collect in roof air vents, making them more attractive to insects. A good clean every few months can make a big difference. A vacuum with a nozzle attachment or even a pressure washer (gently, of course) can clear out unwanted gunk.
4. Use natural repellents
If you’re not keen on chemical sprays, there are plenty of natural ways to deter flies. Essential oils like eucalyptus, peppermint, and citronella are like kryptonite to these little pests. Try mixing a few drops with water and spraying it around your vents. Not only will it keep the flies away, but your house will smell fresh too.
5. Keep an eye on rangehood and bathroom exhaust vents
Flies don’t just get in through roof air vents, they also sneak in through rangehoods and bathroom exhaust fans. If you’ve noticed more flies than usual, it’s worth checking those areas too. The Dragon Vent range is designed to work with rangehoods and will help stop flies from creeping in through those openings. Plus, it’ll make your rangehood quieter by increasing airflow and reducing motor noise. Two problems solved at once!
The best vent colours for your roof
If you’re worried about your vent standing out, you shouldn't. The Dragon Vent range comes in many colours to match your roof. Got a tin roof? You can pick from Surf Mist, Monument, Shale Grey, or Dune. If you’ve got a tiled roof, there’s black and terracotta too. So, not only do you get a vent that keeps the flies out, but it also looks like it was always meant to be there.
Flies in your home are a nightmare, but stopping them from sneaking in through your roof air vents is pretty simple. Swap out old vents for ones with built-in mesh, seal any gaps, keep them clean, and use natural deterrents when needed. And if you want an easy, long-term fix, order from Dragon Vents Australia, because no one wants to share their kitchen with a swarm of flies!
