Australian experts have issued a warning about chemical resistant 'super nits'.

The scalp insects are becoming more resilient to over the counter chemicals.

Lice are wingless insects that live on a host and can transfer from one to another.

But one mum said using MooGoo's new $29.50 lice killer instantly worked.

With term four of school now underway, experts have issued a warning about chemical resistant 'super nits' that have been discovered in Australia.

The final school term is often the 'worst time of year for head lice' with one in four children infested.

Melissa Murray, science communicator from the Australian Museum's Search and Discover department in Sydney, said new breeds of lice are evolving and they are becoming more resilient to the over the counter chemicals that we have been using, including Permethrin, Pyrethrin and Malathion.

'The chemicals we've been using are becoming less effective,' she said.

'Traditional products seem to be losing their efficacy as some invertebrates, such as head lice, can evolve and adapt to the chemicals that are being used to kill them off.'

The lice have specifically adapted legs to hold onto human hair and feed on human blood, Ms Murray said.

'Like most invertebrates, head lice shed their exoskeleton (hard outer layer) as they grow, so you often find the two different skeletons (the nit, and the shed skin – at least two) in the hair,' she said.

Mum-of-two Lauren Bents, 30, said nits are a frequent occurrence in her house and are a 'constant source of frustration', as her four-year-old son recently had an outbreak and passed them on to his 17-month-old brother.

'I don't know how many generations were in their hair, but there were loads,' Lauren said, adding: 'I can always tell which child had them first depending on how many there are.'

The life cycle of head lice is usually three weeks, but the insects can multiply quickly by laying eggs, known as nits, on the scalp that hatch two weeks later.

If removed from the host, the bugs can survive for two days on brushes, combs, hair accessories, hats, headphones and bedsheets, so it's important to wash every item used the same time while treading the head.

The lice can even live on eyebrows and eyelashes, feasting on human blood several times a day.

'Every individual will respond to a parasite differently like they do with mosquitoes etc, and the scratching can be both from the feeling of them crawling around, as well as the host's reaction to the louse's saliva,' Ms Murray said.

'However, scratching open wounds can lead to a bacterial infection, so as well as treating the head lice, they also might need antibiotics.'

While nits were commonly often found in only young children, Ms Murray said the insects are becoming more prevalent in teenagers and young adults, who often put their heads close together to look at each other's social media platforms.

But after battling with different types of remedies for years, Lauren said she saw instant results from using the new $29.50 Head Lice & Egg Destroyer Kit from Australian natural skincare brand MooGoo.

'It's the only thing that works; the kids have stopped scratching and we're no longer battling with persistent lice,' Lauren said.

'I think everyone should be talking about nits, it shouldn't be taboo,' she said, adding: 'I'm of the opinion that if more parents talked about infestations and weren't ashamed of it, it wouldn't be so rife.'

Using MooGoo's 'cow' plastic shower cap can also play a key role to remove any 'super nits'.

'Combing the treatment through and popping a shower cap on for half an hour or so is that best way to do it,' Ms Murray said.
