Guarding Your Whiskered Companions: Navigating Cat-Safe Mosquito Repellents in Australia


As the weather heats up, mosquitoes make their inevitable appearance, posing a nuisance and potential health risks to both humans and our furry feline friends. In many parts of Australia, including Queensland where our company is based, mosquitoes are incredibly common, making it all the more important to learn and discuss the topic of mosquito repellents for cat owners. However, not all mosquito repellent products are safe for cats. In this blog post, we will explore the common mosquito repellents available in the market and provide insights on which ones are suitable for households with cats in Australia. Let's dive in and discover the dos and don'ts of mosquito control while keeping our beloved cats safe and sound.

Understanding the Dangers

Cats possess unique physiological differences that make them more vulnerable to certain substances, including some mosquito repellents. One category of mosquito repellents to be cautious of is pyrethroids, which include natural pyrethrins derived from chrysanthemum flowers and synthetic pyrethroids such as cypermethrin, permethrin, and deltamethrin. These substances are widely used in various mosquito repellent products, including coils, mats, and liquid vaporizers.

Pyrethroids are generally safe for humans and dogs but can be toxic to cats due to their reduced ability to metabolise and detoxify certain chemicals. Cats lack an essential liver enzyme called glucuronyl transferase, which plays a crucial role in metabolising pyrethroids. As a result, pyrethroids can accumulate in a cat's system, leading to potential poisoning.

According to reports from the Journal of Veterinary Emergency & Critical Care, even small doses of pyrethroids, such as direct skin contact with products containing 0.05-0.1% or higher concentrations, can cause toxic effects in cats. In fact, spraying just 1 millilitre of 45% cypermethrin on a 4.5-kilogram cat's skin can be life-threatening.

Given the potential risks associated with pyrethroids, it is essential to exercise caution when considering mosquito repellent products for a cat-friendly household. While cats can tolerate low concentrations of pyrethroids, it is strongly recommended to seek alternative options to protect your cat from mosquitoes.

The Good and the Bad: Reviewing Common Mosquito Repellent Products

Pyrethroids: The Risks and Recommendations for Use Pyrethroids, including natural pyrethrins and synthetic pyrethroids, are commonly found in mosquito repellent products

such as mosquito coils, mosquito mats, and liquid vaporizers. While these products are effective at repelling mosquitoes, they pose a significant risk to cats. It's crucial to avoid using pyrethroid-based mosquito repellents in households with cats due to the potential toxicity.

The toxic effects of pyrethroids on cats include tremors, hypersalivation, incoordination, muscle tremors, and even seizures. If you suspect your cat has come into contact with pyrethroid-based mosquito repellents or is exhibiting any of these symptoms, seek immediate veterinary attention.

As an alternative, consider using cat-safe mosquito repellent options, which we will discuss in detail later in this blog post.

Plant-Based Repellents: Are They Safe for Cats? Plant-based mosquito repellents often utilise essential oils from plants such as citronella, eucalyptus, lemongrass, and lavender. While these repellents are generally considered safe for humans, it's important to exercise caution when using them around cats.

Cats have a different metabolic process compared to humans, and their bodies may not effectively metabolise certain compounds found in plant-based repellents. Additionally, some essential oils can be toxic to cats, especially when ingested or applied in concentrated forms.

To ensure your cat's safety, it is advisable to avoid direct application of plant-based mosquito repellents on your cat or in their immediate surroundings. Instead, focus on using these repellents in outdoor areas or by creating a mosquito-free zone that is inaccessible to your cat.

In the next section, we will explore other considerations and safer options for repelling mosquitoes in a cat-friendly household.

DEET: Assessing the Potential Dangers DEET (N,N-Diethyl-meta-Toluamide) is a widely used and effective mosquito repellent ingredient. It is commonly found in many insect repellent sprays and lotions. However, when it comes to cats, caution is advised.

While there is limited research on the specific effects of DEET on cats, there have been reported cases of toxicity in both cats and dogs. The American Society for the Prevention of Cruelty to Animals (ASPCA) suggests avoiding the use of any DEET-containing products on cats or dogs.

It is important to note that DEET can be absorbed through the skin and may pose a risk if cats lick or ingest it while grooming. To safeguard your cat's well-being, it is best to refrain from using DEET-based mosquito repellents in households with cats.

The blog post will continue with more information about safer alternatives and guidelines for using mosquito repellents in a cat-friendly home.

Icaridin (Picaridin): Is it a Safer Alternative? Icaridin, also known as Picaridin, is another commonly used mosquito repellent ingredient. It is considered an effective alternative to DEET, providing long-lasting protection against mosquitoes. When it comes to cats, there is limited research on the specific effects of icaridin.

Although there is no definitive evidence suggesting icaridin is toxic to cats, it is recommended to exercise caution. The World Health Organization (WHO) classifies oral ingestion of icaridin as low toxicity for humans, but as there haven't been specific safety studies conducted for cats, it's best to avoid direct application of icaridin-based mosquito repellents on your cat.

If you choose to use icaridin products in a cat-friendly household, ensure that your cat doesn't come into direct contact with the treated surfaces and take precautions to prevent your cat from licking or ingesting the repellent.

Mosquito Coils and Other Repellent Options: Analysing Their Effects on Cats Apart from spray-on and lotion-based mosquito repellents, other options like mosquito coils and mats are commonly used to repel mosquitoes. While these products can be effective in reducing mosquito populations, caution should be exercised when using them around cats.

Mosquito coils and mats often contain pyrethroids, as mentioned earlier, which can be toxic to cats. Additionally, the smoke emitted by burning mosquito coils or mats may irritate your cat's respiratory system. It is advisable to avoid using mosquito coils and mats in enclosed spaces where cats spend a significant amount of time, such as bedrooms or living rooms.

In the next section of the blog post, we will discuss safety guidelines for using mosquito repellents in a cat-friendly home, including proper application techniques and precautions to ensure your cat's well-being.

Safety Guidelines: Protecting Your Cat from Mosquitoes

Now that we have reviewed various mosquito repellent options and their potential risks to cats, let's explore some essential safety guidelines to keep your feline companion safe from mosquitoes:

Consult with Your Veterinarian: Before using any mosquito repellent products on or around your cat, it is crucial to consult with your veterinarian. They can provide personalised advice based on your cat's health condition, age, and specific needs. Your veterinarian may recommend cat-safe alternatives or suggest additional preventive measures to minimise mosquito exposure.

Avoid Direct Application on Cats: Unless specifically designed and labelled for use on cats, it is best to avoid applying mosquito repellents directly to your cat's fur or skin. Cats are meticulous groomers, and they can ingest or lick substances applied on their bodies, potentially leading to toxicity.

Create a Mosquito-Free Zone: Designate a safe and mosquito-free area for your cat, such as a screened-in porch or a well-sealed indoor space. This allows your cat to enjoy the fresh air without the risk of mosquito bites. Ensure there are no open windows or gaps that could allow mosquitoes to enter the designated area.

Use Cat-Safe Alternatives: Fortunately, there are cat-safe alternatives available to repel mosquitoes. Look for products specifically formulated for cats or natural options that have been proven safe for feline companions. These may include citronella-free, plant-based repellents that do not contain essential oils known to be toxic to cats.

Mosquito-Proof Your Home: Minimise the entry of mosquitoes into your home by keeping doors and windows properly sealed with screens. Repair any damaged screens to prevent mosquitoes from entering your living spaces. Additionally, eliminate any stagnant water sources around your property, as they serve as breeding grounds for mosquitoes.

Consider Indoor Mosquito Control Methods: Implement additional measures to control mosquitoes indoors. This may include using mosquito nets or screens on windows and utilising fans, as mosquitoes are weak fliers and can be deterred by air currents. Regularly clean and maintain your indoor spaces to eliminate potential mosquito breeding sites.

By following these safety guidelines, you can effectively protect your cat from mosquito bites and reduce the risk of exposure to harmful mosquito repellents.

In the final section of this blog post, we will summarise the key points discussed and provide a conclusion with practical recommendations for cat owners in Australia. Stay tuned for the last section of our comprehensive guide to mosquito repellents for cat-friendly households.
