Does vanilla extract repel mosquitoes? Our entomologists explore the benefits and drawbacks of this all-natural alternative

Spending time outdoors, be it on your deck, patio or whilst busy gardening is a joy but one snag remains an irritation – mosquitoes. And, they can end up bothering you both outside and inside as early as February in some regions.

With nasty, itchy bites, mosquitoes emerge in spring and peak during summer, drawn out by the increasing temperature. While repellents are an effective way to keep bugs and bites at bay, the majority contain a whole host of harsh chemicals, leaving many hoping for a more natural alternative that works.

Vanilla extract is often touted as a great way to get rid of mosquitoes, and the good news is, it actually works. Here, entomologists share their expertise.

Does vanilla extract repel mosquitoes?

When it comes to scents that deter mosquitoes, vanilla extract can be used as a natural pest control method. The theory behind its success is that much like other potent plant derivatives, the strong smell of vanilla covers the scent of humans, eliminating the attraction for mosquitoes.

Shannon Harlow-Ellis, associate certified entomologist at Mosquito Joe, explains, 'Vanilla extract (such as Great Value Pure Vanilla Extract available at Walmart) will mask the odor mosquitoes are searching for when looking for a blood meal. It has a natural appealing scent,' which is far less offensive than other, deet-based repellents such as Repel 100 Insect Repellent available at Amazon, which provides 10-hour protection, but is 98% deet. It can also help extend the efficacy of other DIY repellents.

Kyle Sebach, director of operations at All U Need Pest Control, adds, 'Like citronella, vanilla extract portrays a very strong smell that mosquitoes typically do not like.'

The drawbacks of this method

So, while vanilla extract can be used as a natural way to repel mosquitoes, it's not a flawless solution. For starters, says entomologist Shannon, it's expensive.

'It must be pure vanilla extract,' she advises, such as Watkins Pure Vanilla Extract available at Amazon. 'Vanilla with other additives (which is usually cheaper) can attract insects with the sugary smell,' resulting in an entirely adverse effect. You will also need to use a considerable amount.

The scent of vanilla is also not ever-lasting, with entomologist Shannon saying it will only last between 30 and 45 minutes when used alone. But, this can be extended when combined with other repellent scents, like a citronella candle, such as the Mosquito Repellent Candle available at Amazon.

Additionally, vanilla extract won't work to tame infestations when trying to get rid of mosquitoes in the kitchen, for example. Dr. Jim Fredericks, board certified entomologist and senior vice president of public affairs at the National Pest Management Association (NPMA), warns, 'We do not recommend trying any DIY treatment methods for pest infestations, as they typically do not provide a long-term solution.

'Those who suspect an infestation should call in the pros immediately. Pros are trained to identify the species of pest infesting a building and tailor their control efforts to that pest’s biology and behaviors.'

Our experts also warn that just like any repellent products, natural or not, allergic reactions are a risk.

Shannon adds, 'With any product applied to the skin, there is always a risk of reactions.' For that reason, if you do want to use vanilla extract as a repellent, test it on a small area of your skin first, or set it out in shallow dishes rather than rubbing it directly on your body.'

Alternative mosquito repellents solutions

1. Limit the amount of stagnant water in your garden

Mosquitoes are attracted to the smell of stagnant water, so reducing sources of it in and around your home will help fight numbers.

Pest expert Kyle advises, ‘Overturn buckets that have water in them, and contraptions that may hold water. This will ensure that no mosquitoes are using this water to lay in and hatch eggs,’ which will worsen the problem.

2. Use apple cider vinegar

Apple cider vinegar is an effective solution to repelling mosquitoes, particularly when mixed with peppermint oil, another scent garden pests hate, like this 100% pure one from Walmart. This will also helps to mask the acidity of the vinegar.

Entomologist Shannon directs, 'Mix two ounces of apple cider vinegar with two ounces of distilled water and 40 drops of peppermint oil in a small spray bottle and shake the mixture.

This can then be sprayed onto your skin (patch test first) or used to mist the air.

3. Light citronella candles

Can citronella repel mosquitoes? As well as being a relatively cheap option, citronella candles really do work.

Pest expert Kyle recommends, 'I would suggest lighting citronella candles in your outside area to reduce mosquitoes,' which can also double-up as part of your table-scaping for an al fresco candle-lit dinner.

This will also work to repel ladybugs, and, if you choose to grow citronella, it's one of the best wasp repellent plants, too. You can also use citronella in your home to keep mosquitoes away from the front door.

4. Use coconut oil

You can also use coconut oil, such as this bestselling coconut oil from Amazon, to repel mosquitoes, which entomologist Shannon particularly recommends if you have children.

‘Mix 2.5 oz of coconut oil and 15 drops of lavender or rosemary oil in a small jar (such as the Mainstays Clear Glass Airtight with Lid Storage Jar available at Walmart) and shake,’ she says. ‘This mixture is applied by hand,’ and will soften skin, too.

5. Sweep away food

If you regularly enjoy cookouts, chances are your backyard is filled with food crumbs.

Pest expert Kyle says, ‘A lot of people have grills and other food sources that are typically in back patios where you find mosquitoes. Limiting these food particles would slightly help.’

Simply sweep away crumbs with an outdoor brush, such as the Yocada 18 Inch Push Broom available at Amazon, and pop them directly into a trash bag. If you have a trash can outdoors, ensure you empty it regularly to avoid attracting both warm weather and winter garden pests.
