What You'll Learn
Citronella candles are toxic to pets
Citronella candles are insect-repellent products made from essential oils extracted from the leaves and stems of lemongrass plants. While these candles are popular for keeping mosquitoes and other bugs at bay, they can pose certain risks to pets.
Firstly, citronella candles can be a fire hazard and are not intended for indoor use. They should be placed on non-flammable surfaces and kept out of reach of pets to prevent burns.
Secondly, the essential oils in citronella candles can be toxic to pets if ingested. This can cause gastrointestinal irritation, including abdominal pain, vomiting, and diarrhoea. Ingesting large amounts can lead to more severe health issues, including liver damage. Pet owners should seek immediate veterinary advice if they suspect their pet has ingested citronella products.
Thirdly, the smoke from citronella candles can cause respiratory irritation in pets. It is recommended to use these candles in well-ventilated areas and to avoid placing them near water sources where pets may be tempted to drink.
Furthermore, some pets may experience skin irritation or allergic reactions to citronella. It is advised to introduce these products gradually and observe the pet's reaction. Discontinue use and consult a veterinarian if any signs of discomfort or sensitivity occur.
Overall, while citronella candles can be effective insect repellents, pet owners should be cautious and take necessary precautions to ensure the safety and well-being of their furry friends.

Candles produce carbon monoxide
Candles are a source of relaxation for many people, but they can also be a source of carbon monoxide, a toxic and potentially fatal gas. Carbon monoxide is formed when there is incomplete combustion of materials containing carbon, such as candle wax. This occurs when there is insufficient oxygen for the candle to burn properly, resulting in carbon monoxide formation instead of carbon dioxide.
The amount of carbon monoxide produced by a candle depends on various factors. The type of wax used in candle-making significantly affects its burning characteristics and the byproducts it emits. Candles made from paraffin wax, a petroleum derivative, tend to produce more soot and potentially more carbon monoxide compared to natural alternatives like beeswax or soy wax. Soy wax and coconut wax candles are believed to emit lower amounts of carbon monoxide.
The design and material of the candle wick also play a crucial role in combustion efficiency. Wicks that are too long or contain metal cores may burn unevenly, leading to erratic flames and increased soot and carbon monoxide production. Additionally, burning candles for extended periods can cause excessive carbon buildup on the wick, hindering oxygen from reaching the flame and increasing the risk of carbon monoxide formation.
The number of candles burning simultaneously also contributes to carbon monoxide levels. A single candle typically produces only trace amounts of carbon monoxide. However, when multiple candles are lit at once or consecutively, the amount of carbon monoxide in the air increases. In enclosed or poorly ventilated spaces, carbon monoxide can accumulate to dangerous levels, posing a serious health risk.
To minimize the risk of carbon monoxide poisoning, it is essential to ensure proper ventilation when burning candles. Keep windows and doors open to allow for adequate air circulation and the dissipation of carbon monoxide. It is also recommended to regularly extinguish candles after a few hours and let them cool before relighting to maintain optimal burning conditions.
While candles can produce carbon monoxide, the risk can be mitigated by following proper candle maintenance and placement guidelines. By taking these precautions, individuals can safely enjoy the ambiance and fragrance of candles while minimizing the potential hazards associated with carbon monoxide exposure.

The combustion process creates toxic compounds
While citronella candles are made from natural oils, there are still some dangers associated with their use. Inhalation of the smoke from citronella candles can cause breathing issues in pets. However, it is unclear whether the candles are harmful to humans. Citronella oil can be mildly irritating to the skin and eyes and may cause skin allergies in some individuals with prolonged or frequent exposure.
The combustion process involves burning a fuel (reductant) and an oxidant, usually atmospheric oxygen, to produce oxidized, often gaseous products, in a mixture called smoke. This process releases toxic compounds, especially when combustion is incomplete.
Complete combustion is challenging to achieve because the chemical equilibrium is not always reached, and there may be unburnt products, such as carbon monoxide, hydrogen, and carbon (soot or ash). The resulting smoke is typically toxic due to the presence of these unburnt or partially oxidized compounds.
Carbon monoxide, a poisonous gas, is formed during incomplete combustion when there is insufficient oxygen to completely burn the fuel. When inhaled, carbon monoxide displaces oxygen in the blood, impairing its ability to transport oxygen. This can have severe health consequences, including respiratory issues.
Additionally, combustion at high temperatures in atmospheric air, which contains nitrogen, can produce small amounts of nitrogen oxides (NOx). The combustion of nitrogen is more favorable at higher temperatures. NOx species, particularly nitrogen dioxide (NO2), are significant pollutants that contribute to the formation of smog and harm aquatic life and vegetation.
Therefore, the combustion process in citronella candles, especially when used indoors, can potentially release toxic compounds that may have adverse effects on respiratory health, similar to the impact of other combustion sources like motor vehicles and industrial processes.

Candles may cause breathing issues for pets
While candles can be a great way to set the mood or get rid of unpleasant smells, they may cause breathing issues for pets.
Scented candles, in particular, can trigger an allergic reaction or irritate existing breathing problems in dogs. For example, fragrances and scented oils containing naphthalene can affect a dog's lungs and eyes. Similarly, exposure to phthalates, often found in candles, has been linked to cancer in pets. If ingested, a candle can get stuck in a dog's gastrointestinal tract, leading to an upset stomach or intestinal blockage.
Citronella candles, a popular choice for repelling mosquitoes, can also be harmful to pets. When pets inhale the smoke from citronella candles, it can cause breathing issues. Additionally, if ingested, citronella can cause severe illness or even death in pets.
Other common household scents can also be dangerous to pets. For instance, while small amounts of spices like cinnamon and nutmeg added to foods are usually non-toxic, larger amounts can cause respiratory issues and even toxicity in pets. Essential oils, such as cinnamon oil, can be toxic even in small amounts.
To keep your pets safe, it is important to follow some precautions. Keep candles out of your pet's reach and opt for unscented, soy, coconut, or vegetable-based wax candles with a cotton wick. If you notice any breathing issues in your pet, contact a veterinarian immediately.
