How To Get Rid Of Hover Flies On Patio
Hover flies, also called syrphid flies, are those little black-and-yellow insects that zip around your flowers and sometimes hang in the air like tiny helicopters. They’re usually harmless and even helpful in the garden, but I understand the frustration when they crowd your patio while you’re trying to relax or entertain. In this guide I’ll share practical, gardener-tested ways to reduce hover fly numbers on your patio while keeping balance in the garden.
Know Your Enemy: What Hover Flies Are and Why They’re Here
Hover flies look like bees or wasps but don’t sting. Adults feed on nectar and pollen; their larvae often eat aphids and other soft-bodied pests. So before you wage war, know that many hover flies are beneficial.
“I used to swat at them until I learned they were aphid-munching allies. Now I only take action when they become a nuisance on my patio.”
They’re attracted to: blooming plants, sugary drinks, compost, damp organic matter, and areas where aphids live. Removing those attractants is the most effective long‑term solution.
Immediate Steps to Reduce Hover Flies on the Patio
If you want quick relief so you can enjoy your outdoor space, try these immediate, non-lethal tactics I use on busy summer afternoons.
- Move food and sweet drinks indoors or cover them with lids. Hover flies love sweet liquids.
- Use a portable fan. A gentle breeze makes it hard for them to hover and they rarely stay where it’s breezy.
- Close doors and windows or use screens to prevent them from drifting inside.
- Provide an alternative feeding station a few yards away. Place a saucer of sugar water amid flowering plants to divert them from the patio.
Simple DIY Trap (If You Must)
I prefer to avoid killing beneficial insects, but if numbers are out of hand, a gentle trap helps reduce them without pesticides. Cut the top off a plastic bottle, invert it into the base, add a little sweet liquid with a drop of dish soap to break surface tension. Place it away from seating areas. It’s crude but effective, and you can release flies outside if you prefer.
Long-Term Solutions That Work
For a patio that stays pleasant season after season, focus on habitat and prevention. Here’s what has worked best in my yard.
- Tidy up aphid hotspots. Inspect roses, beans, and new growth. Treat severe infestations with a strong water spray, insecticidal soap, or introduce ladybugs. Fewer aphids means fewer hover fly larvae and fewer adults attracted to your patio.
- Manage compost. Keep compost bins closed, covered, well-aerated, and away from seating. Decomposing sugary residues attract flies.
- Prune and space plants. Improve airflow and reduce moist hiding spots where flies rest.
- Choose less-attractive plants near the patio. Replace overly fragrant or nectar-heavy pots right next to seating with non-scented foliage or herbs like rosemary and lavender—these can deter some flies while still looking nice.
- Introduce predators naturally. Encourage swifts, bats, and spiders by providing habitat; they’ll help keep flying insects in check.
Plant Choices and Landscaping Tips
It may sound counterintuitive, but limiting highly attractive nectar sources immediately adjacent to your patio makes a big difference. Move pollinator magnets (like buddleia and certain salvias) a few meters away. Planting savory, rosemary, or taller ornamental grasses closer to seating creates a less appealing zone for hover flies without harming garden biodiversity.
Non-Toxic Repellents and Barriers
I avoid aerosol or broad-spectrum insecticides on the patio because they kill pollinators and beneficials. Instead try these gentler options:
- Essential oil sprays: A mix of water and a few drops of eucalyptus, peppermint, or citronella can be misted around seating areas. Reapply frequently.
- Sticky traps placed away from flower beds: catch excessive numbers without spraying plants.
- Light management: hover flies are less active under certain lighting. Try warmer, lower-intensity outdoor lights rather than bright white floods.
When to Embrace Them Instead of Fighting
Here’s a gardener’s confession: I’ve learned to share my patio more. Hover flies are excellent pollinators and their larvae control aphids. If they’re not landing on my food or bothering guests, I tolerate them and enjoy the benefits in my vegetable patch.
Choosing tolerance over elimination can save time, protect the garden’s health, and maintain natural pest control. I only intervene when their numbers make the patio unpleasant.
Checklist: Quick Action Plan
- Clear food and drinks or cover them.
- Move nectar-rich pots away from seating.
- Set up a fan or move seating to a breezeier spot.
- Inspect and treat aphid sources in the garden.
- Manage compost and damp organic matter.
- Use gentle traps or essential oil sprays as a last resort.
Final Thoughts
Getting rid of hover flies on your patio is mostly about removing what attracts them and making the seating area less hospitable, not about chemical warfare. With a few smart changes—tidying aphid hotspots, covering sweet foods, adding airflow, and placing pollinator plants a short distance away—you can enjoy your patio without losing the ecological benefits hover flies bring.
Gardening is a constant lesson in balance. I hope these tips help you reclaim your patio while keeping the garden’s helpful helpers happy and healthy.
