So, what other option is there? Well, believe it or not, there are many plants and herbs that will repel flies and insects away from your backyard. Let’s get to it.

Plants That Repel Flies

Here is a list of the plants that will help you enjoy a life free from annoying flies and insects. Many plants are easy to grow and will help you repel your backyard insects for a long time.

1) Basil

Basil thrives both indoors and outdoors. Fresh basil is proven by many to be an effective insect repellent.

You can crush its leaves and rub it directly onto your skin, but it doesn’t work for too long. However, here is another way to prepare a basil spray that will last awhile:

  • Boil 4 ounces of water into a container.  (Be sure to use only the amount of water recommended for the recipe.) Too much water weakens the mixture’s potency.
  • Add 4-6 ounces of freshly washed basil leaves. (Leaves can stay attached.)
  • Let it steep for several hours, then remove leaves and squeeze all the moisture of basil leaves into the mixture. Let it cool. The infused liquid should strongly smell of basil.
  • Add 4 ounces of vodka into the infused mixture, (vodka will use as a carrier for the mixture) mix thoroughly and voila! You can now enjoy an affordable homemade insect repellent you can spray when going outdoors.

Reminder: Keep the spray out of your children’s reach, and when you spray, keep away from your eyes, nose, and mouth as it can be harmful.

Aside from basil adding flavor to different types of soups, salads, and various pork and chicken recipes, it can also be of great aid to improve the taste of vegetables like asparagus, tomatoes, and peppers.

2) Bay Leaf

Dried bay leaf is an effective natural insect repellent. It wards off annoying insects like cockroaches, ants, and also fleas when sprinkled around your home.

It can act just like insecticide sprays sold commercially. Unlike commercial insect killers, they are best and safe for home use where your children and pets play around.

The pungent scent of bay leaf is what deters insects. Others believe that essential oils (myrcene and eugenol) commonly extracted from bay leaves play a vital role in discouraging these insects.

How to use bay leaves to repel insects:

Place leaves in the areas where you often spot insects. It can be under your cabinets, counter-tops, around trashcans, and even along your baseboards.

However, the pungent odor from the leaves wears off after a few days, and it loses its effectiveness too. With that being said, replace bay leaves once a week to keep insects from coming back.

Type of insects bay leaves can repel:

  • Cockroaches
  • Fleas
  • Wasps and flies
  • Sugar ants (one of the common household pests)
  • Spiders
  • Moths

How to use Lavender for bug prevention:
  • You can do so by putting a small amount onto your skin. If your skin is sensitive and lavender is too strong for you, diluting it with other essential oils like jojoba, sweet apricot, almond, or sesame oil is also a great idea.
  • However, if you prefer not to put anything directly onto your skin, another way to enjoy its benefits is to get lavender sachets, pillows, or another form of dried lavender.
  • A small amount of lavender oil is also efficient if mixed with your regular body lotions or moisturizer.
