In the Cape Fear region, mosquitoes are as much of a guarantee as the ocean.

But some local horticulture experts believe there are some herbs and plants that could offer a little relief for your backyard.

Although many wive's tales and legends tell that a variety of plants and herbs can help ward off mosquitoes, New Hanover County Cooperative Extension director Al Hight is skeptical of their true impact.

"A lot are touted to repel mosquitoes and insects, but I don't know how many are that effective," he said, citing many have to be touched to be effective. "None of them are going to give you the same protection you would put on yourself."

Still, Hight and Meg Shelton, owner of Shelton Herb Farm in Leland, agree that mosquitoes are an unavoidable consequence of coastal and Southern dwelling and every little but helps.

"It's certainly not going to hurt anything," Hight said.

For those who still want to explore possible landscaping additions that could provide an extra layer of protection, here are some suggestions:


Shelton suggested the native Southern wax myrtle, a small tree or scrub with small blue berries that can be a nice aesthetic addition.

She said the olive-green, aromatic foliage can provide protection from mosquitoes as long as it is rubbed, crushed or ground. She also said placing the leaves around your yard where they can be walked on and activated can be beneficial.

Similarly, pennyroyal, a flowering plant with purple blooms, can be used to deter insects when crushed.

"Place the pennyroyal around stepping stones so you can step on it and pick up the scent on your shoes," Shelton said.

Hight said lavender is often rumored to be good mosquito protection but the coastal climate is not kind to its growth.

Scented geraniums may also help keep mosquitoes away, Shelton said.


"A lot of the herbs have insect-repelling qualities," Shelton said. "Many of them are aromatic, so mosquitoes don't like them."

Among herbs commonly mentioned as deterrents are rosemary, lemon balm and mints like catnip (which Shelton said will also ward off cats).

However, Hight said herbs and any backyard plant aren't likely to help repel mosquitoes or other insects without being activated by touch to release the oils and scent.

"Just planting the plant or herb won't do the trick," he said.

Hight said one herb that does have a potent enough scent automatically that it could ward off mosquitoes: basil.

"Basil exudes such a scent by itself without having to be crushed or handled," he said.
