Make DIY Fly Traps Using Soda Bottles
If you’d rather use home remedies for flies in the garage, you can make DIY fly traps to remove the pests from your garage. Old soda bottles make the ideal tool for killing off those pesky flies in your garage. Follow this method to setting up this trap. This is the old school answer to how to get rid of flies in your garage that still works today.

Step 3 – Replace the top part of the soda bottle with the opening facing the bottom of the bottle base.
Step 4 – Place these soda bottle fly traps on the floor around your garage and keep them away from kids and pets.
The flies are attracted to the liquid in the bottle. They’ll enter through the opening to get at the liquid, but they won’t be able to escape, eventually drowning in the liquid. Replace the traps as they start to fill with flies. Remember, the scent of dead flies attracts more of them.
Proper Lawn Maintenance & Composting to Prevent Flies
Flies breed in compost bins and in long grass in your yard. Keep the lawn trimmed and ensure the compost heap is as far away from the garage as possible to stop flies from entering your garage. A decomposing compost heap doesn’t attract flies, provided you use the correct waste.
Don’t place kitchen scraps like dairy or meat waste in the compost heap. Stick to only using organic matter from the garden in your compost heap. Animal feces and cooking oils also attract flies to the compost heap.
Don’t let your compost heap get too wet for extended periods. This effect causes rotting, which attracts flies. It also stops the composting process, turning the compost into sludge unsuitable for your garden; it just stinks.

The citrusy scent of this product keeps flies and mosquitoes away from the area. They’re available in deodorizers and candles to help keep flying pests away from your garage and other locations around your home.
Eucalyptus, lavender, cloves, basil, and white vinegar are other options. Pick up some herbs and essential oils from the store and leave them around the garage. They’ll stop the flies from entering the area.
