Getting rid of flies in your garage can feel impossible, especially in warmer months. Flies are annoying and can spread germs. If you want a clean, safe garage, you need to take action. This guide will help you understand why flies come, how to get rid of them, and how to stop them from coming back.
The steps are simple and easy to follow, even if you are new to pest control.
Why Flies Invade Garages
Flies enter garages for three main reasons:
- Food sources: Trash, spills, pet food, and even dead insects attract them.
- Shelter: Garages offer shade and protection from weather.
- Breeding sites: Damp areas, rotting materials, and open containers are perfect for laying eggs.
Most garages provide these conditions without owners realizing it. Flies can smell food from far away—some species detect odors from over 1 mile. Once inside, they multiply quickly. One female can lay up to 500 eggs in her lifetime.
Identifying The Types Of Flies
Not all flies are the same. Knowing the type helps you find their source and remove them.
Common garage flies:
- House flies: Gray, about ¼ inch long. Attracted to garbage and food.
- Fruit flies: Tiny, reddish-brown. Like sweet spills and old fruits.
- Drain flies: Fuzzy, moth-like. Found near drains and moist areas.
Here’s a quick comparison:
| Fly Type | Size | Common Attraction | Breeding Site |
|---|---|---|---|
| House Fly | 6-7 mm | Garbage, food scraps | Rotting materials |
| Fruit Fly | 2-4 mm | Sweet liquids, fruits | Fermenting produce |
| Drain Fly | 3-5 mm | Damp, organic matter | Drains, moist corners |
Spotting the right type helps you target the right cleaning and prevention methods.

Many beginners forget the importance of drains. Flies often breed in hidden spots, especially floor drains. Using enzyme cleaners prevents drain flies.

Sealing Entry Points
Flies get inside through tiny gaps. Sealing the garage keeps them out.
Common Entry Points
- Doors: Gaps under or around doors.
- Windows: Cracks in frames or screens.
- Vents: Uncovered vents or broken grilles.
How To Seal
- Apply weather stripping to doors.
- Use caulk for cracks around windows.
- Install mesh screens on vents.
Here’s a comparison of sealing methods:
| Entry Point | Best Sealing Method | Estimated Cost | Difficulty |
|---|---|---|---|
| Door | Weather stripping | $10-$20 | Easy |
| Window | Caulking | $5-$15 | Moderate |
| Vent | Mesh screen | $8-$25 | Easy |
Beginners often miss vents. Even small vent holes can let in dozens of flies.
Fly Control Methods: What Works Best
You can use different tools to catch and kill flies. Some methods work better than others, depending on your garage size and fly type.
Mechanical Traps
- Sticky strips: Hang near doors or trash.
- Bug zappers: Good for bigger garages.
Chemical Sprays
- Insect sprays: Kill on contact. Use carefully and ventilate the area.
- Residual sprays: Last longer but may not be safe for pets.
Natural Remedies
- Vinegar traps: Mix apple cider vinegar with a drop of dish soap in a jar.
- Essential oils: Flies dislike peppermint, eucalyptus, and lemongrass.
Professional Products
- Fly bait stations: Used for heavy infestations. These can be bought online or from hardware stores.
Comparison of trap effectiveness:
| Trap Type | Effectiveness | Cost Range | Safe for Pets? |
|---|---|---|---|
| Sticky Trap | Moderate | $2-$8 | Yes |
| Bug Zapper | High | $20-$60 | Yes |
| Chemical Spray | Very High | $5-$15 | No |
| Vinegar Trap | Low | $1-$3 | Yes |
For most beginners, start with sticky traps and vinegar traps. They are cheap and safe.
Preventing Flies: Long-term Strategies
Once you remove flies, keep them away with these habits.
Regular Cleaning
- Sweep and mop the garage weekly.
- Empty trash bins twice a week.
- Clean up pet food and spills daily.
Manage Moisture

- Fix leaks quickly.
Proper Storage
- Store food and pet supplies in sealed containers.

When To Call A Professional
If flies keep coming back after you clean and seal, you may need help.
- Infestation lasts more than 2 weeks.
- You see hundreds of flies daily.
- Flies are coming from unknown sources.
Pest control experts use strong treatments and identify hidden breeding sites. The cost ranges from $100-$300 for most garages.
Professional help is needed if you have allergies, pets, or children who could be harmed by sprays.
Common Mistakes Beginners Make
- Ignoring hidden sources: Flies breed in drains, under boxes, and inside bins.
- Using too much spray: Chemical sprays can cause health problems if used often.
- Not sealing entry points: Flies enter through tiny gaps you may not notice.
- Leaving food out: Even small crumbs attract flies.
- Forgetting outdoor cleanup: Flies start outside and move indoors.
Avoid these mistakes for faster results.
Practical Tips For Fast Results
- Pick a cleaning day and stick to it every week.
- Use two types of traps at once for better results.
- Check drains and corners for hidden eggs.
- Keep a fly swatter handy for quick action.
- Record what works and what doesn’t. Adjust your methods.
Example: A garage owner in Florida saw almost zero flies after sealing the door, cleaning drains, and using peppermint oil near entry points.
Real Data: How Effective Are These Methods?
Studies show that:
- Cleaning and sealing entry points reduces flies by 70% in most garages.
- Sticky traps catch about 50 flies per week in an average 2-car garage.
- Vinegar traps work best for fruit flies, but only catch 10-15 flies weekly.
- Professional pest treatments can reduce flies by 90% in one week.
