Reasons to Repel Gnats

Reasons to Repel Gnats1

Gnats are a group of tiny and harmless but highly annoying flying insects you can often find inside your home and in the backyard. They fly in clouds and typically don’t bite but can be highly aggressive. The additional problem is that they multiply rapidly.

It sounds unbelievable, but some species can lay a few hundred eggs on one piece of fruit. You can expect to see them in moist areas and around rot fruit and compost. Besides, they find human sweat incredibly attractive, making it difficult for people to work in the fields and orchards.

Pour a solution into a spray bottle and sprinkle it throughout your house. Since only 7 to 8 drops of tea tree essential oil applied to the cat’s or dog’s skin can be fatal to these pets, you should be careful when using it.

8. Rosemary

You can use this beautiful plant in three ways to effectively deter gnats. Grow a bush in your yard or make a spray from essential oil and apply it over the house. The final option is to soak the crushed rosemary twigs in water and let them sit for a few hours before spraying the area with this fragrant liquid.

9. Lemon thyme

11. Citronella

Citronella grass is well-known as an excellent repellent against mosquitoes and gnats. You can plant citronella grass in your yard, use aromatic sticks, or make DIY candles.

One of the most popular options is to make an efficient water solution of citronella essential oil or its crushed leaves and a few drops of dish soap. Avoid using these products inside your home, but they are helpful outdoors, particularly during hot summer days.

This proven repellent for gnats disrupts laying eggs and larvae development. The best thing is that neem oil is harmless to your pets and plants.

Make a spray by combining one tablespoon of Castile soap with two tablespoons of neem oil and pour them into a cup of warm water. After applying it inside your home, you can do the same in the yard. It efficiently eliminates eggs laid around the plant roots, under mulch piles, and in compost. 

17. No Natz

No Natz is a natural, hypoallergenic, DEET-free spray made of several essential oils, including:

  • Rosemary essential oil
  • Citronella essential oil
  • Lemongrass essential oil
  • Geranium essential oil

Its advantage is that you don’t need to make an efficient repellent yourself. Spritz No Natz on your body and clothes, or light a candle to enjoy a gnat-free yard.

18. DEET

DEET is not an all-natural product, but it is an excellent repellent worth mentioning. It efficiently deters mosquitoes, gnats, and ticks, protecting people and animals from Lyme disease, Zika virus, and West Nile virus. Be careful with this commercial product since it can cause skin irritation and rash in direct contact.

19. Softener sheets

Softener sheets1

Dryer sheets are a convenient way to keep gnats away from your surroundings. Since they often smell like lavender, geranium, or lemon balm, you can efficiently use them instead of essential oils. On the other hand, these sheets contain chemicals that also deter bees, butterflies, and hummingbirds from your backyard.

Summary

Numerous scents keep gnats away, and you should pick out the one you like. The best way to protect your yard is to plant some aromatic flowers, while essential oils are ideal for homes. Experiment and discover which choice is the best for you and base it on your preferences and each repellent’s feature.
