The saying goes that an ounce of prevention is worth a pound of cure. So, the first thing you can do to get rid of nuisance flies outside instantly is to take away the things that are attracting them to your property. Getting rid of their reason for coming to your patio could solve the problem before it starts.

So, what reasons do flies have for coming to your lawn and patio area? Flies are attracted to fresh food, drinks, decaying foods, feces, and more. Simply put, they’re trying to eat.

Reducing flies in your yard could be a matter of:

  • Moving your trash cans farther away from the patio
  • Cleaning up pet feces instead of letting them sit
  • Moving bird feeders farther away from your home
  • Frequently cutting your grass and trimming brush to reduce hiding spots
  • Removing sources of standing water

Performing these tasks can give flies fewer reasons to stay around your home, cutting down on the number of flies that stick around.

Many methods exist to help you get rid of flies outside instantly. Other ways to cut down on these pests may take some time. Your best bet is to use a combination of approaches along with preventative measures to reduce the number of flies around your patio. Use these techniques to quickly rid your area of flies.

1. Put Up Sticky Fly Traps

Sticky fly traps are unpleasant because they have a powerful scent. Yet, few things attract the flies in your yard to one area faster than these. Once they flock to these sticky traps, the flies will get stuck to them, resulting in their demise. While unpleasant, these traps can clear a patio area very quickly.

2. Use Flying Insect Spray to Instantly Kill Flies

If you have a concentration of flies that are particularly interested in your outdoor trashcan, you can always spray them with flying insect killers. Commercial varieties of flying insect killers typically affect the creature’s body via a neurotoxin. Once sprayed, the flies will not be able to move their muscles and will pass away. Oftentimes, this happens in seconds. The only downside is that you’ll have to keep interrupting your activities to spray the flies.

3. Use Insect Foggers to Wipe Out Pests

Another chemical option to get rid of flies outside instantly is a fogger. Outdoor foggers for flying insects use the same principle as indoor roach foggers. The main difference is that a person applies these via a spray, and they can only be used on calm days or the mist will blow away. Once you spray an area with the fogger, flies will stay away for hours, days, or weeks according to some brands. The spray will immediately kill or drive away any flies in the area.

4. Implement Light-Based Fly Traps

Flies are naturally attracted to bright lights. So, if you are sitting on your patio at night, using a light-based fly trap can be a great way to clear the yard. Of course, these light traps do not instantly kill a dozen flies. However, they will leave you and your guests alone to focus on the light and slowly dwindle in numbers. Once they strike the trap, they’re zapped by electricity and die.

You can leave the light on after you go inside to let the trap do its work all night, so you wake up to fewer flies in the morning.

5. Use Strong-Smelling Cleaners to Ward Off Flies

Flies dislike the scent of pine oil. Naturally, it is smart to use their dislikes against them to make them leave your backyard. While it is not a good idea to spray undiluted pine oil around your backyard, you can use a diluted mixture in some areas.

Try mixing a cleaner with pine oil or pine oil itself in a 50/50 mixture with water. Use that to wipe down tables and chairs or to spray in places where flies congregate. They should disperse soon after.

6. Put Down Fly Bait and Wait for the Bugs to Eat

Severe fly infestations can warrant the use of fly bait. However, fly bait is harmful to humans and animals that consume it. That means you should only put this down in places where you have problems with flies that children and pets cannot access.

Once you scatter this bait, flies will consume it believing that they have stumbled upon a tasty morsel. After they eat it, the flies will start rapidly dying off. This type of fly bait is often criticized for its indiscriminate killing of wildlife, though. It is best to use this as a last resort.

7. Use Citronella Candles

The smell of a citronella candle will temporarily drive off flies.


Burning a citronella candle is a good way to get flies to leave an area. These are simple tools that work with various levels of efficacy. However, if you want to get rid of flies outside instantly, light a few of these types of candles or torches. The biggest problem is that the flies will return to whatever food or scent attracted them to your yard after the scent dissipates. Citronella candles are best used in conjunction with other tools to remove flies from your patio.

Getting rid of flies outside can be a challenge. However, several preventative and proactive measures can be used together to reduce their populations outside your home. Of course, getting rid of flies inside your home is another challenge altogether, but the process can use similar measures. Be ready to change some elements of your life, like where you store your garbage, to stop flies from disrupting a nice barbeque.
