Understanding Hoverflies
What are Hoverflies?
Hoverflies are insects that belong to the Syrphidae family. They are often mistaken for bees or wasps due to their similar appearance, but they are harmless and do not sting. Hoverflies are important pollinators and help to control pests in gardens and outdoor spaces.
Why are Hoverflies a Problem?
Hoverflies can be a problem for gardeners and outdoor enthusiasts because they can damage plants and flowers. The larvae of hoverflies feed on aphids, which can be beneficial, but they can also damage the leaves of plants. Additionally, adult hoverflies can be a nuisance when they swarm around people or food.
Identifying Hoverflies
Hoverflies can be identified by their distinctive markings and behavior. They have black and yellow stripes on their bodies, and they hover in place when they fly. Unlike bees and wasps, hoverflies have two wings instead of four, and they have large, compound eyes.
Preventing Hoverflies
Removing Hoverfly Attractants
One way to prevent hoverflies from infesting your garden or outdoor space is to eliminate conditions that attract them. This can include removing overripe fruit, cleaning up spilled food or drink, and keeping garbage cans tightly sealed. Additionally, you can avoid planting flowers that are particularly attractive to hoverflies, such as marigolds and sunflowers.
Using Natural Repellents
Another way to prevent hoverflies is to use natural repellents. These can include planting herbs such as mint, lavender, and basil, which are known to repel hoverflies. You can also make a natural repellent spray by mixing water and vinegar in a spray bottle and spraying it around your garden or outdoor space.
Controlling Hoverflies
Using Insecticides
If you have a severe infestation of hoverflies, you may need to use insecticides to control their population. The best insecticides for hoverflies are those that contain pyrethroids, which are a type of synthetic insecticide. However, it is important to use these insecticides carefully and according to the instructions on the label.
Trapping Hoverflies
You can also use traps to capture and eliminate hoverflies. One effective trap is a yellow sticky trap, which can be hung near plants or flowers that are infested with hoverflies. The yellow color of the trap attracts the hoverflies, and they become stuck to the sticky surface.
Using Beneficial Insects
Another way to control the population of hoverflies is to introduce predators that feed on them. One effective predator is the lacewing, which feeds on the larvae of hoverflies. You can attract lacewings to your garden by planting flowers such as dill, fennel, and yarrow.
Conclusion
In conclusion, there are several methods to get rid of hoverflies outside. Preventative measures such as removing attractants and using natural repellents can be effective in keeping hoverflies at bay. If you have a severe infestation, you may need to use insecticides or traps to control their population. Introducing beneficial insects such as lacewings can also be an effective way to control the population of hoverflies. By following these methods, you can enjoy your outdoor space without the nuisance of hoverflies.
