What are Citronella Candles & How to they work?

Summer is here, and that means relaxing evenings in the garden, ideally not interrupted by flying insects! 

We look at citronella candles, the candle offering a zesty burst of summer citrus for every garden gathering, and packs a punch in helping to deter mosquitos and flying insects, making those long summer nights in the garden, more enjoyable.

So, what are Citronella candles?

Citronella candles contain citronella oil, a natural ingredient extracted from certain species of lemongrass. Commonly used outdoors, the fragrance from Citronella candles can help to reduce the number of mosquitoes and other flying insects in the immediate area, whilst also creating a pleasant atmosphere.

Citronella candles work best in calmer conditions and within a relatively small area around the candle. That makes them perfect for a relaxed evening outside.

Citronella Oil, what is it & why is it used in candles?

Citronella is an essential oil obtained from varieties of lemongrass native to tropical regions.

It’s popular in candles for several reasons:

  • A fresh, citrus like cent, topped with herbal notes
  •  A distinct aroma that deters mosquitoes and other flying insects

How Do Citronella Candles Work?

As the candle burns, citronella is slowly released into the surrounding air. This distinct aroma helps to mask odours that may attract mosquitoes.

From a 200g candle, the scent of Citronella remains localised to the area, meaning citronella candles are most effective when placed close to where people are sitting.

How effective are citronella candles?

Citronella candles can be effective at deterring mosquitoes and other insects, but it’s key to remember that the 200g candles burn in a localised area. Citronella candles are designed to help reduce the presence of mosquitoes in the immediate area around the candle. They are not intended to eliminate insects completely or provide the same level of protection as insect repellents applied directly to the skin.

Their effectiveness depends on several factors, including:

  • Wind and air movement
  • The size of the outdoor space
  • The number of candles used
  • The distance between the candle and seating areas
  • The local insect population

On still summer evenings, they can be a useful addition to patios, balconies and garden dining areas.

Where Should You Use Citronella Candles?

Citronella candles are best suited to outdoor spaces such as:

  • Patios
  • Decking areas
  • Garden tables
  • Balconies
  • Outdoor dining areas
  • Camping pitches

How Many Citronella Candles Should You Use?

Citronella candles burn in localised areas, given that a breeze can disperse the fragrance, it is recommended to place the candles in sheltered locations in your home and garden. 

For larger garden gathering, using multiple candles can help to distribute the fragrance more evenly.

We recommend to position several candles around the edge of the seating area to create a more consistent fragrance.

Do Citronella Candles Smell Nice?

Yes, citronella has a fresh, lemon-like aroma with subtle grassy and herbal notes creating a clean outdoor scent that many people associate with summer evenings in the garden.
