Are your Plants Attracting Flies? Plants That Attract Flies
You have just learned about plants that repel flies. But do you know that a few plants attract flies too? Flies and pests love the lack of air circulation and can get attracted to houseplants. Here are a few plants that attract flies that you might need to remove from your house or garden:
People typically fall in love with the aromatic seeds and leaves of this ornamental plant. But dill also attracts ladybugs, wasps as well as hoverflies. But these flies eat harmful pests like aphids, so consider growing dill in the garden instead of in the house.

The big, yellow sunflowers get the attention of hoverflies and wasps apart from the onlookers. You might need to get rid of them in case of an infestation.
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 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.
