Flies are more likely to infest your garage than even your home. It is easier for them to get in, because of the big garage door that opens several times and may even remain open for long periods. Flies are more than an irritation, they are disease carriers! So how to get rid of flies from your garage?

Your war against flies in your garage is a two step process. KILL & STOP.

To get rid of flies from your garage you can use fly killer sprays or traps. Traps can be homemade, sticky strips or use UV light to attract the flies. To keep them out of your garage you need to keep your garage and its surroundings clean and create entry barriers such as screens.

How to Get Rid of Flies from Your Garage?

If you are dealing with one fly, you may be able to swat it down, after several failed attempts. But if your garage has been infested with flies, a swatter is not going to be much use. You need more help!

By the way, by getting rid of flies in your garage, you are also taking a step towards getting rid of spiders in your garage. Because flies are food for spiders. If spiders do not find flies they may give your garage a miss.

Homemade Fly Traps are an Easy Solution to Killing Flies

Making & using homemade fly traps is a cheap and easy way to get rid of flies from your garage.

Vinegar & Dish Soap Trap

Mix 2-3 spoons of apple cider vinegar with a few drops of dishwashing detergent in a glass. Cover with cellophane, securing it to the glass with a rubber band. Make a few holes in the cellophane, large enough for the flies to get in.

The flies will be attracted to the vinegar. Soap reduces the surface tension of the vinegar. The flies are not able to stay on top of the vinegar and will sink.

Make a Fly Trap from a PET Bottle

It’s so simple a kid could make one. Take an empty PET bottle and cut off the top quarter. Invert it and place it in the bottom part of the bottle. Seal the joint with an adhesive or tape. 

Pour in a bit of sweet liquid to lure the flies and your trap is ready. The flies will get in but will not know how to get out. Place a few, if you like, in different locations in your garage.

Hang Sticky Fly Traps in your Garage

Sticky Fly Traps are essentially strips which will attract the flies and trap them using an adhesive. The fly will be attracted, land on the strip, get stuck and will not be able to fly away.

You can check out Catchmaster Sticky Fly Trap Ribbon – Indoor/Outdoor Fly Catcher Insect Killer- Pack of 20 Rolls at Amazon.

UV Light Fly Traps are an Efficient way to get rid of Flies

Light Traps use UV light bulbs to attract many types of flying insects including flies. Once the fly enters the trap, some models will zap them, others will trap them with a piece of sticky disposable paper.

Take your pick, but I prefer the silent version. Throw away the stick paper after enough flies have been trapped. Hopefully your garage will have got rid of most of the flies in a few days. 

I like the Faicuk WS108 Wall Sconce Fly Light Trap for Capturing Flies, Moths, Gnats, Mosquitos and Other Flying Insects – 13″x7.5″x5.5″ from Amazon. It looks beautiful too!

This Fly Light Trap will get rid of Flies, quietly.

You can get rid of common pests like flies, mosquitoes, spiders, moths and roaches from your garage. I have a blog post on each of these pests that you can check out at

Alternatively you can try out Atomic Zapper. It is multipurpose.

I recommend the Atomic Zapper from BulbHead. This powerful device is a 2-in-1 ultrasonic pest repeller and bug zapper. It uses ultrasonic soundwaves to drive rodents crazy but doesn’t bother you and your pets. Atomic Zapper™’s blue light technology attracts and zaps flying insects. Order it by clicking on the link below:

Why is your Garage Infested with Flies?

House flies are not born inside your home. They are born outside your home in some dirty spot like a garbage bin, an open drain or rotting fruit. 

They can fly long distances to find food. They find it difficult to enter your house because you rarely open the doors and windows. Your house is climate controlled. 

You have an HVAC (Heating, Ventilation & Air Conditioning) system installed and working. In addition, your doors & windows likely have insect screens too!

The big wide garage door, on the other hand, opens at least a few times a day. It is an open invitation for flies to walk in (sorry, I mean fly in!). 

Add to it the fact that, quite often, your garage is not as clean as your home. Flies will find lots of food there. Open soda cans and partially eaten burgers. Garbage bags and dead cockroaches.

Your garage also provides them with a cooler & darker place than the hot outdoors.

How to Stop Flies from Infesting Your Garage?

Now that you have got rid of the flies you must stop them from infesting your garage in the future.

You must take action on two fronts:

  1. Keep the garage & surroundings clean
  2. Create “entry barriers” to the garage

Keeping the Garage Clean

You must treat your garage as a part of the living space of your home. So you must apply all the practices of good housekeeping to your garage as well. 

Basically this means that you must

  • declutter your garage regularly
  • organize your garage storage
  • use airtight plastic storage containers as far as possible
  • not keep sweet beverages or snacks in open cans or plates

You must also regularly and frequently clean up your garage. If you like having beverages and snacks in the garage, clean up immediately. It is a good idea to have a small refrigerator in the garage

Be extra careful about spills & waste disposal of beverages, snacks, especially sweet items like donuts & ice creams. If your garage has a bad smell, you are sending an open invitation to the flies outside.

Storage of unclean gardening equipment, outdoor activity or camping gear and sports equipment such as hockey gear, golf bags & clubs can also be a source of food for flies in the garage.

Clean them properly before storage. Cleaning will also increase the life of the equipment.

Keeping the Garage Surroundings Clean

The female flies lay 75-150 eggs at a time or around 500 eggs in their very short life. They lay these eggs, known as maggots, in dirty places so that they have access to food immediately. 

Flies love to lay their eggs in garbage bins, open or leaking sewer lines, pet waste, rotting food, especially fruits.

To stop flies from infesting your garage, you have to deprive them of all their breeding grounds around the garage. Keep the surroundings clean!

Creating “Entry Barriers” in your Garage for the Flies

There are at least two ways in which you can deter flies from entering your garage.

Use Smell Flies Hate (but we like!)

Flies hate the smell of certain plants. There are 8 herbs that repel flies: 

  1. Basil
  2. Lavender
  3. Rosemary
  4. Mint
  5. Catnip
  6. Pennyroyal
  7. Tansy
  8. Bayleaf

That is super convenient. Plant some of these herbs near your garage door. Not only do you keep the flies away, you get a fresh supply of aromatic herbs for your kitchen too!

Use Garage Door Screens

The size of an adult housefly is about ¼-inch. So screens can be used to block their entry. Keeping the doors & windows of the house shut is not that difficult. If you do like to open them on summer evenings to get a bit of fresh air, you should have the door and window screen in place.

All this is a little bit more difficult, when it comes to the garage door. Nonetheless, you must use garage door screens whenever the door is open for long periods.

Of course, the ultimate and the best option for you is to make your garage climate controlled. It has a lot more benefits than just keeping flies out of your garage.

A few Basic Facts about Flies (Interesting!)

Flies are insects. Believe it or not there are over 110,000 species of flies around the world, Of these 18,000 species are found throughout North America. Many of them may not even be of much interest to us as homeowners. 

It’s the house flies and mosquitoes that invade our homes. (Yes mosquitoes are flies too!). Both are annoying. Worse, both can carry and spread diseases.

“House flies are typically gray in color and have four black stripes on their thorax. Adult house flies are about 1/8-1/4” long. They have slightly hairy bodies, a pair of wings and compound red eyes that contain thousands of individual lenses, giving them wider vision. House flies do not have teeth or a stinger.”

Flies live for just 30 days, but females can lay upto 500 eggs in that short time. Needless to mention they can proliferate and swarm an area at an alarming pace. As you would have guessed, they lay their eggs in really dirty places such as garbage bins, rotting food, compost piles and excrement.

Some fun (and annoying) facts about flies.

  1. They can taste food with their feet and suck on liquid food as they do not have teeth.
  2. They eat all the time, sh*t all the time and spread harmful bacteria as they fly around.
  3. You can’t swat a fly because they can see behind them and can process images 4 times faster than us.

Bottom Line

The bottom line is that flies infesting your garage is not just annoying. Flies are filthy, unhygienic and can spread several diseases including 

“enteric infections (such as dysen- tery, diarrhoea, typhoid, cholera and certain helminth infections), eye infections (such as trachoma and epidemic conjunctivitis)”

Flies have a place in the ecosystem, just not in your home or garage.

True flies fill ecological niches as predators, parasites and prey. Some true flies, particularly when in their larval stages, also act as decomposers.

You must and can get rid of flies in your garage by using sprays or traps. Even more important is to prevent future infestation of flies in your garage. You can do this by keeping your garage and it’s surroundings clean and putting “entry barriers” such as screens.
