How to Repel Mosquoitoes Naturally

We hope we are soon moving to beautiful acreage - where mosquitoes are more prevalent than they are where we currently live. I really don't love the idea of spraying my family with DEET on a daily basis, so I've been researching some more gentle, natural ways to deter mosquitoes from biting us.

I have not yet tried any of these remedies (because we haven't moved yet), so the information I'm sharing here is strictly from researching trusted herbal sites, university pages, and the like. Experiment with me, and please let me know what works for you!



Plants that Repel Mosquitoes

In my research, I found many sources that claimed simply having these plants growing in your yard would repel mosquitoes. I am skeptical. It's believed these plants work by having a strong scent - a scent that covers up the smell of you to mosquitoes passing by. But most of these plants have a far stronger scent when the leaves are crushed (which is why they work in homemade mosquito sprays; more on that later.).

Nevertheless, I think it's probably worth placing these plants in areas where you are most likely to be troubled by mosquitoes - like a picnic table or grill. Just know that these plants will all work far better when crushed and rubbed on your skin. (But do use common sense; before you cover your whole body, it's a great idea to rub a little over a small area of your body and wait to see if you have any type of reaction.)

Lemon Balm (Melissa officinalis)
This is an easy to grow herb that has many medicinal uses, too. It likes sun or part shade, and can grow to 2 feet high. Like most herbs, it can take over the garden if left to it's own devices, so I recommend putting it in pots. Zones 4 -9. Learn more here.

Catnip (Nepeta faassenii)
In  a 2010 study by the Iowa State University Department of Entomology, scientists discovered that oil from catnip is 10 times more effective than DEET in repelling mosquitoes. This is another easy to grow herb that needs to be potted or it will take over your garden. Use with caution if you have one or more cats. Not only will kitties eat and roll in this plant, but it acts as a hard drug for them and, much like LSD, will give them flashbacks. Zones 4 - 8. Learn more here.

Pyrethrum (Tinacetum cinerariifolium)
Pyrethrum is said to be excellent not just for repelling mosquitoes, but also many other insects, including aphids, bed bugs, leaf hoppers, cabbage worms, spider mites, and ticks. Zones 3 - 7. Learn more here.
Pyrethrum.
Peppermint (Mentha x piperita)
Another easy to grow herb that should be potted, but which is thought excellent at keeping mosquitoes at bay. It grows in full sun or part shade and can get up to 18 inches high. Zones 3 - 7. Learn more here.

French Marigold (Tagetes patula)
French marigolds contain pyrethrum, which is used in many natural commercial insect repellents. Marigolds are very easy to grow, and gardeners often plant them near vegetables to repel aphids, too. Zones 1 - 10. Learn more here.

Lavender (Lavandula angustifolia)
Lavender is an attractive herb with some medicinal uses. It's also said to repel mosquitoes. There are about a gazillion different types of lavender, so choose one that has a strong scent and fits your growing requirements. Zones 4- 9. Learn more here.

Basil (Ocimum americanum)
This herb is best known for it's important role in the kitchen, but it also acts as a mosquito repellent. Zones 4 and up. Learn more here.

Garlic (Allium sativum)
Eating garlic may repel mosquitoes - but only if you eat enormous quantities. However, the plants themselves are said to keep mosquitoes at bay - and garlic is not only a healthy addition to your diet, but medicinal, too. Zones 3 - 9. Learn more here.

Floss Flower (Ageratum)
This pretty flowering plant grows between 6 and 20 inches tall, depending upon the variety. Choose a variety with a strong scent. Zones 3 - 9. Learn more here.

Rosemary (rosmarinus officinalis) 
Rosemary is an excellent cooking herb, has medicinal properties, and is said to repel mosquitoes. It loves a warm spot and will grow up to 5 feet tall. Zones 6 to 10. Learn more here.

Snowbrush (Ceonothus velutinus)

This old timey flower is a great ground cover, and is said to repel mosquitoes while attracting butterflies. It's also medicinal. Zones 5 - 9. Learn more here.

Lemon Thyme (Thymus vulgaris)
Some people say any thyme will repel mosquitoes; others say only lemon thyme will. Regardless, thyme is an easy to grow herb that I recommend putting in pots so it doesn't spread. Thyme is also an excellent kitchen herb, and medicinal. Zones 4 -11. Learn more here.

Lemon Verbena (Aloysia triphylla)
Another excellent kitchen and medicinal herb said to repel mosquitoes. Zones 9 - 10. Learn more here.

Citronella (Cymbopogon nardus)
Most likely you've heard of this plant, because it's the main ingredient in many mosquito repelling products sold in stores. Yet despite citronella's reputation, some people who've tried growing the plant to repel mosquitoes say citronella doesn't work at all, even when the strong-scented leaves are crushed. I include it here because plenty of others disagree. Citronella grows to be about 5 feet tall, but can be grown in containers, as well as directly in the soil. Zones 9 - 11. Learn more here.

DIY Natural Mosquito Repellent Sprays

I've looked at a lot of homemade mosquito sprays, but these three (or variations on them) appear to be the most effective.

Four Thieves Herbal Mosquito Repellent Recipe

Place 2 quarts of apple cider vinegar in a glass jar. Add 12 tablespoons of The Bulk Herb Store's Vinegar of the Four Thieves mixture. Put the lid on the jar and store in a cool, dark location, shaking once a day. After 2 weeks, strain, reserving the liquid. Pour the liquid into a clean jar; crush a few cloves of garlic and add to the jar. Allow to soak for 3 days in a cool, dark location, then strain again, reserving the liquid. Store in the refrigerator. Shake before every use.

Herbal Mosquito Repellent Recipe

Coarsely chop mosquito repelling herbs like lemon balm, catnip, lemon verbena, and lavender. (See the list of plants, above, for more ideas on what you could include.) Chop enough to fill a glass jar. Pour rubbing alcohol, witch hazel, or vodka over the herbs, leaving 1/2 inch headspace. Place a lid on the jar and put it in a sunny location for 2 weeks, shaking the jar every day. Strain, reserving the liquid. Pour liquid into a spray bottle. Shake before every use.


Essential Oil Mosquito Repellent Recipe

Fill a spray bottle 3/4 full with either witch hazel, rubbing alcohol, or vodka. Add the following essential oils:
  • 10 drops mint
  • 10 drops citronella
  • 5 drops rosemary
  • 5 drops eucalyptus
  • 5 drops lavender
  • 5 drops cloves
Add distilled water until the bottle is full. Shake before every use. (If desired, you can experiment with the essential oils of other plants mentioned above.)


Homemade Mosquito Trap

This DIY trap is all over the internet. All you need is a 2 liter plastic bottle, 1 cup brown sugar, 1 cup warm water, and 1 teaspoon of active dry yeast. See the complete instructions over at DIY & Crafts.
