Conduct a Comprehensive Garage Cleanup

A clean garage is less likely to attract flies. Start by removing all trash, food particles, and standing water, as these can serve as breeding grounds for flies.

Close Off Access Points

Flies can enter your garage through small cracks and gaps. Inspect your garage for any openings, paying special attention to windows, doors, and vents.

Seal cracks or gaps with caulk or weatherstripping, and ensure your garage door closes tightly. Installing screens on windows and vents can also help prevent flies from entering while allowing proper ventilation.

Utilize Fly Deterrents

Various commercial fly repellents are available in the market, such as sprays and electronic devices. Apply these repellents around your garage, focusing on entry points and areas where flies tend to congregate.

You can also use natural deterrents like essential oils, including lavender, eucalyptus, and lemongrass, known to repel flies.

Invest in Improved Garbage Bins

Flies are attracted to the smell of garbage, so keeping your trash cans clean and tightly sealed is essential. Invest in garbage bins with secure lids and consider using trash bags that neutralize odors.

Remember to empty and clean your trash cans regularly to minimize fly attraction.

Create DIY Fly Catchers

Homemade fly traps can be an effective and budget-friendly solution to control flies in your garage. One popular DIY fly trap involves:

  • Using a plastic bottle.
  • Cutting off the top.
  • Inverting it.
  • Filling it with a sweet liquid like sugar water or fruit juice.

The flies will be attracted to the scent and trapped inside the bottle. Place these traps around your garage to catch flies and reduce their population.

Maintain Short Lawn and Distance Compost from Your Garage

Keeping your lawn well-trimmed and your compost pile away from your garage can help reduce the number of flies in the area.

Flies are attracted to tall grass and decomposing organic matter, so maintaining a short lawn and moving your compost pile to a location further from your garage will make it less appealing to flies.
