The tropical paradise of Bali is a dream destination for many Australians, offering sun-soaked beaches, vibrant culture, and a chance to unwind. However, there's a lesser-known threat lurking in the shadows of this idyllic setting that could turn your holiday into a nightmare. An Australian expat living in Bali has issued a stark warning about a seemingly unassuming insect that's not only ubiquitous across the island but also packs a venomous punch capable of causing severe skin reactions.


Montana Lowrey-Palmer, who has called Bali home for several years, recently shared her harrowing experience with the notorious tomcat beetle. She recounted a close call with the insect that almost made contact with her phone. 'I put my phone down next to it and it almost crawled on my phone. As soon as I saw it I picked my phone up, I freaked out,' she said in an interview Montana's quick reaction spared her from the beetle's harmful effects, as she wisely refrained from swatting it away. 'It doesn't even have to bite you,' she explained. 'It has an acid that gets on your skin and does the damage.'


The tomcat beetle, often mistaken for an ordinary ant due to its size, can be identified by its distinct coloration and the potency of its venom, which is said to be more powerful than that of a cobra. While the beetles don't bite and are not lethal, their venom can cause extreme skin irritation, resulting in painful welts, burns, and even permanent scarring.


Montana herself bears a scar from a previous encounter with a tomcat beetle, a stark reminder of the insect's lasting impact. 'I remember having this welt on my leg and I didn't know what it was from. It was quite small, probably only the size of my thumb... but I discovered it was from a tomcat... I still have a scar three years later,' she shared.

Her story is not unique. Natalie Carroll, a 24-year-old from the Gold Coast, suffered severe burns after inadvertently brushing off a tomcat beetle while asleep during her Bali holiday. And in 2023, a nurse from Mudgee was left with a 'big yellow oozing' blister after coming into contact with one, noting that the beetles were 'everywhere' but seemed harmless at first glance.

The advice from Montana is clear: 'If you ever see this animal in Bali, literally run.' This sentiment is echoed by Dr Swaid Abdullah, an expert in veterinary parasitology, who advises against crushing the beetle as it releases the toxin that can be absorbed by our skin.


For those unfortunate enough to make skin contact with a tomcat beetle, immediate action is crucial. Washing the affected area with soapy water and applying 'cold wet compresses' can mitigate the damage, as the toxin penetrates the skin slowly. 'Washing immediately after exposure can help remove much of the toxin before it has time to harm the skin,' Dr Abdullah advised. 'Afterwards, use cold wet compresses and seek medical help if it gets worse.'

As we continue to embrace the joys of international travel, it's important to stay informed about the potential hazards that come with exploring new destinations. While Bali remains a beloved spot for many Aussies, being aware of the risks and knowing how to respond can ensure your holiday memories are of the pleasant variety.
