Do Flies Eat Aphids?

Do Flies Eat Aphids in their Diet?

Yes, flies do eat aphids. Flies are known to be voracious predators and feed on a wide range of insects, including aphids. In this article, we will explore the relationship between flies and aphids, their feeding habits, and the benefits of having flies as natural predators in your garden.

Flies as Aphid Predators

Flies, particularly hoverflies and syrphid flies, are natural enemies of aphids. These flies are attracted to the sweet honeydew secreted by aphids, which serves as their primary food source. However, they also consume aphids directly, making them effective predators in controlling aphid populations.

Hoverflies are often mistaken for bees due to their similar appearance, but they lack stingers and are harmless to humans. They are beneficial insects that play a crucial role in maintaining ecological balance by preying on aphids and other garden pests.

Hoverflies and Aphid Control

Hoverflies are highly effective aphid predators, and their larvae, known as maggots, are particularly voracious feeders. A single hoverfly larva can consume up to 400 aphids during its development stage. This makes them valuable allies in organic gardening, as they help control aphid infestations without the need for harmful pesticides.

Hoverflies are attracted to gardens with a diverse range of flowering plants, as they rely on nectar and pollen for energy. By planting a variety of flowers that bloom throughout the season, you can attract hoverflies and encourage them to stay in your garden, providing natural aphid control.

Benefits of Flies as Aphid Predators

Having flies as natural predators in your garden offers several benefits:

Organic Pest ControlFlies provide an eco-friendly solution to aphid control, reducing the need for chemical pesticides that can harm beneficial insects and the environment.
Cost-EffectiveBy relying on flies as natural predators, you can save money on expensive pest control products.
Low MaintenanceOnce flies are attracted to your garden, they will continue to control aphid populations without requiring any additional effort on your part.
BiodiversityEncouraging a diverse range of insects, including flies, promotes biodiversity and a healthy ecosystem in your garden.

Attracting Flies to Your Garden

If you want to attract flies to your garden to control aphids, consider the following tips:

  • Plant a variety of flowers that bloom at different times to provide a continuous food source for flies.
  • Include plants that produce nectar-rich flowers, such as marigolds, lavender, and sunflowers, to attract flies.
  • Avoid using chemical pesticides, as they can harm flies and other beneficial insects.
  • Provide a water source, such as a shallow dish with pebbles, for flies to drink from.
  • Minimize the use of artificial lighting at night, as it can disrupt the natural behavior of flies.

Creating Fly-Friendly Habitats

Creating fly-friendly habitats in your garden can further enhance the presence of flies as aphid predators. Consider the following:

  • Leave some areas of your garden undisturbed, allowing natural vegetation to grow and provide shelter for flies.
  • Install a small pond or water feature, as flies are attracted to water sources for breeding and drinking.
  • Introduce companion plants, such as dill, fennel, and yarrow, which attract flies and provide additional food sources.

By implementing these strategies, you can create an environment that attracts and supports flies, ensuring effective aphid control in your garden.


In conclusion, flies do eat aphids, and they play a vital role in controlling aphid populations in gardens. By attracting flies to your garden through the use of diverse flowering plants and creating fly-friendly habitats, you can harness the natural predatory abilities of flies to maintain a healthy and balanced ecosystem. Embracing flies as aphid predators offers organic pest control, cost savings, and promotes biodiversity, making it a win-win situation for both your garden and the environment.
