How to Keep Flies Away From Your Patio or Backyard BBQ

There’s nothing worse than trying to enjoy a beautiful evening on the patio — grilled food ready, drinks poured — only to be bombarded by buzzing, bothersome flies. They’re more than just a nuisance. Flies can carry bacteria, disrupt meals, and make guests uncomfortable. But here’s the good news: with a little knowledge and the right tactics, you can take back your patio.

This guide walks you through the reasons flies target outdoor spaces, what attracts them to your backyard in the first place, and what you can do to keep your next cookout fly-free.

Why Do Flies Love Patios and BBQs?

Flies are drawn to areas that offer two key things: food and favorable conditions. Unfortunately, patios provide both:

• Food waste: Leftover food scraps, sugary drinks, grease, and fruit attract house flies, fruit flies, and blowflies.

• Standing water: Pet bowls, plant trays, or clogged gutters offer breeding grounds for flies, especially in summer.

• Shelter: Patios with overhangs, umbrellas, and shaded areas offer cool resting spots.

• Organic material: Mulch, compost, and lawn clippings can attract flies as they decompose.

So when you fire up the grill, set out snacks, and gather with friends — you’re basically rolling out the welcome mat for winged intruders.

Most Common Flies You’ll Encounter Outdoors

Knowing what you’re dealing with helps you plan your defense. Here are the usual suspects:

• House Flies: Attracted to food, garbage, and animal waste. They’re fast and frustrating.

• Fruit Flies: Drawn to sugary drinks, overripe fruit, and fermented beverages — think wine and beer.

• Blowflies (Blue/Green Bottle Flies): Often found near decaying organic matter, pet waste, or dead rodents.

• Drain Flies: Occasionally hover near moist soil, compost, or mulch beds.

How to Keep Flies Away From Your Outdoor Space

You don’t need harsh chemicals or industrial blowers. These proven, practical steps help eliminate attractants and reduce fly traffic:

1. Clean Up Food and Drinks Immediately

Wipe down tables, pick up dropped food, and cover serving trays. Keep trash bags sealed and disposed of quickly.

2. Use Sealed Trash Bins with Lids

Open garbage invites flies to breed. Use bins with tight-fitting lids and keep them away from gathering areas.

3. Eliminate Standing Water

Empty pet bowls, clean birdbaths weekly, and unclog gutters. Flies lay eggs in moist areas — especially during warm months.

4. Invest in Outdoor Fans

Flies are weak fliers. A fan directed over your seating or grill station can make it difficult for them to land.

5. Use Natural Repellents and Scents

Citronella candles, eucalyptus oil, basil plants, and cloves are known to repel flies. Place them strategically around tables.

6. Keep Compost and Yard Debris Contained

Turn compost regularly and don’t let grass clippings pile up. These create breeding grounds when left unmanaged.

Pro-Level Prevention Tips

For homeowners who want longer-term control, here are a few elevated strategies:

• Install screening around patios or add mesh netting to outdoor gazebos

• Add bug zappers or UV light traps placed away from seating areas

• Schedule regular garbage pickup during the warmer months

• Create distance between food prep zones and trash bins

• Seal cracks in outdoor siding or deck areas where flies may be nesting

When to Bring in the Pros

If flies are constantly invading your space no matter how clean you keep it, there could be a larger issue:

• Hidden nests in mulch or compost

• Decaying material in crawlspaces or gutters

• Drainage issues creating moist soil fly habitats
