Strategic Planting: A Guide on How to Keep Flies Away Naturally

Just having these plants isn’t enough; where you put them matters. A little strategy can turn your collection of plants into a powerful, invisible shield. These are the keep flies away naturally best practices for placement.

Create a Patio Perimeter

Think of your patio or deck as a fortress. Arrange pots of rosemary, lavender, basil, and scented geraniums around the edges. This creates a perimeter of scents that flies are reluctant to cross. Place smaller pots of basil right on your outdoor dining table as a fragrant—and functional—centerpiece.

Guard Your Entrances

Flies often find their way indoors through open doors and windows. Position fly-repelling plants strategically at these entry points. Hanging baskets of petunias, tall pots of lemongrass, or a classic bay tree next to the door can significantly reduce the number of flies that venture inside.

Companion Planting in the Veggie Patch

Incorporate these plants directly into your vegetable and flower beds. Planting marigolds and basil among your tomatoes not only helps deter flies but can also repel other pests like tomato hornworms. It’s a win-win for a healthy, productive garden.

Beyond Plants: Sustainable Garden Habits to Deter Flies

A truly sustainable keep flies away naturally strategy involves more than just planting. Your everyday gardening habits play a huge role in making your yard less attractive to flies in the first place.

Master Your Compost Pile

Flies are attracted to decaying organic matter, and a poorly managed compost pile can become a breeding ground. Ensure your pile has a good balance of “greens” (kitchen scraps) and “browns” (leaves, cardboard). Keep it turned regularly and cover fresh food scraps with a layer of brown material to discourage flies.

Water Wisely and Eliminate Standing Water

While more of a mosquito issue, standing water can attract certain types of flies. Regularly empty saucers under pots, check for clogged gutters, and change the water in birdbaths frequently. A dry environment is less hospitable to pests.

Troubleshooting: Common Problems with Natural Fly Control

“My Plants Aren’t Working! What Now?”

If you feel your plants aren’t pulling their weight, first ensure they are healthy and getting the right amount of sun and water. A stressed plant is less potent. Second, get interactive! Gently rustle the leaves of your basil or rosemary when you walk by to release a fresh burst of their essential oils into the air.

“I Have a Sudden Infestation! Are Plants Enough?”

Remember, plants are primarily a deterrent. If you’re facing a sudden, large-scale fly problem, there’s likely a specific source attracting them (like a hidden spill or pet waste). Identify and remove the source. For immediate relief, you can supplement your plant barrier with simple, non-toxic fly traps made with sugar water and a drop of dish soap in a jar.

“What Does the ‘Care Guide’ for These Plants Look Like?”

The wonderful thing is that most of these plants are quite hardy! The general keep flies away naturally care guide is simple: provide plenty of sunlight (6+ hours for most), use well-draining soil (especially for Mediterranean herbs like lavender and rosemary), and avoid overwatering. A healthy plant is a potent pest-repeller.
