Eucalyptus

The eucalyptus is popular for its silver foliage and offers a host of health benefits from the oils of its leaves.

It was registered as an insecticide and miticide in 1948 in the U.S.

Extracting Plant Oils and Using Them to Repel Flies

You can use the essential oils from a host of plants as discussed above to create a fly-repellent spray for use around the house as well as for your body. The strong scent of these plants typically deters flies.

To make a basic insect repellent from any of these plants, you should have a cup of fresh or dried leaves. Dried leaves are more potent because of their stronger scent. One cup of fresh leaves is equivalent to ⅓ cup of dried ones.

Place the leaves in a 2-quart heatproof container (of any plant you want to use like lavender, catnip, etc.) and boil a quart of water in a kettle simultaneously. Pour the boiling water on top of the leaves and cover it with a lid. Let it brew and cool. Keep in mind that you shouldn’t be drinking this tea before knowing properly about its ingestive properties.

You then have to strain the leaves. Line a strainer with a coffee filter and pour the tea into another container. Remove all the debris to avoid any clogs in your sprayer.

You can also add a teaspoon of oil soap to the liquid before adding it to the sprayer. That would help kill some insects like aphids too.

Other Ways to Repel Flies Naturally

It’s usually preferable to find natural methods to repel flies. Store-bought insecticides can have various side effects when you breathe them in and getting proper pest control can be too expensive when your problem is just flies. Here are a few natural methods apart from using repellent plants:

Vinegar and Dish Soap Trap

You can use a mixture of household vinegar along with some dish soap to trap flies. To do this, mix a cup of apple cider vinegar along with a few drops of dish soap. Pour the mixture into a tall glass and leave it on the kitchen counter. The dish soap will help in drowning any of the flies that land in this mixture.

Cayenne Pepper and Water Spray

Everybody has cayenne pepper at home. So if you want an instant solution for the pests in your garden, instead of getting a separate plant, you can make a quick solution by mixing the two ingredients. Spray this mixture on the upper and lower parts of the infested plants.

Venus Flytraps

Venus Flytraps are carnivorous plants that have been long known to ingest houseflies. It does take a while, but this method is quite effective. As soon as the fly lands on it, the plant closes and kills it with its digestive juices.

Are Flies a Health Hazard?

Flies typically seem harmless creatures that don’t bite humans. So you would usually ignore these little buzzing insects. But these little insects can be a serious hazard to your health because they walk on every nasty thing out there. And their feet have sticky pads which allow them to collect a host of germs from the surfaces they sit on.

And these flies constantly keep sitting on various surfaces and attract a lot of germs. Perhaps their major food supplies are dirt and feces which contain disease-inducing bacteria which can cause typhoid, cholera, dysentery, and so on.

They typically sit on rotten food, garbage, human waste, and more. Moreover, they tend to vomit most of what they eat. Studies have shown that houseflies can carry as many as 200 bacteria with them. Most of these are disease-causing and hence it’s important to get rid of them quickly if they have caused an infestation.

Apart from causing cholera, typhoid, and dysentery, houseflies can even carry parasitic worms and spread leprosy. These diseases can be seriously hazardous and hence houseflies aren’t a typical annoyance. They are much more dangerous than that. If these flies find their way to your food, they can cause serious damage.

Houseflies are present everywhere but you can prevent their infestation by planting one or several of the plants that we have listed here. You can also prevent the invasion of insects, mosquitoes, and more in your yard if you plant these fly-repellent plants in and around your house. They offer a natural yet effective solution to your flies issue.
