Rat poison: time to think again

Just as the use of insecticides does not solve a mosquito problem, vermin are not controlled by repeated use of poisons.

For many years, rat poison has been delivered to households all over the island in totally inadequate cellophane bags. To make matters worse, the instructions are inside, so the poison has to be handled if you want to read them. Foreign residents who do not know Croatian are at a disadvantage. One thought that the white tablet which comes with the red warfarin mixture was the antidote. Luckily, they had no occasion to try it, as the tablet is a separate poison meant for septic tanks, and has no antidote. The antidote to the warfarin is vitamin K. Warnings that the poison is about to be delivered are patchy and haphazard. While the official Stari Grad website always carries advance notice, that has not been the case elsewhere. In Pitve it was usually a small notice taped to the rubbish bin a day or two beforehand. However, during 2016 there has been an improvement in Jelsa, with warnings being given on the Council's website as well as on the Town Hall notice board.

By law, vitamins have to be packaged securely, but it seems that rat poison does not. EU membership has not changed this irresponsible and dangerous custom. The bags are left apparently randomly around the villages. I have found them variously on a window sill, dangling from my post-box, even on top of my car! Delivery is clearly irresponsible. Are the poisons used in a more responsible manner? All too often, they are simply placed in heaps around a property, even where they may be a hazard to pets or young children. The safest way to put down such poisons - if you feel you must - is to use a rigid tube with access holes at either end large enough for mice or rats, but too small for other animals.

While vermin within buildings present a problem and possible health hazard, the same is not true of mice and rats in the wild, which have their place, not least in the natural food chain. For an insight into their lifestyles, see the video below, or click here.

Given regular doses of poison, rats become resistant, so poison is not the solution. On the other hand, although the poison is not supposed to attract other animals, it does, and cats and dogs have died through eating it. The more's the pity, as cats keep rats, mice and even snakes under control. For any major rat infestation, the best methods for avoiding the problem of resistance are to let tenacious dogs like Jack Russell terriers hunt them, or to use traps.

The local councils must spend quite a significant sum of money on distributing these poisons. Looking at the 2015 financial report from Jelsa Council, I was unable to identify exactly how much was spent on the campaigns against vermin and insects, as these items were not identified individually. Is this money being spent wisely? I think not.

In the United Kingdom, poisons against vermin are available, but are not generally distributed by local councils. They were (and maybe still are) distributed on request. Some sixty years ago, when we lived not far from London, my brother, sister and I came home from school to find an unmarked jam jar on the kitchen table. Ever adventurous, my sister delved in. “Cheesy“, she purred, and continued to satisfy her hunger. There was no fridge full of food in those days, indeed no fridge, and the larder was empty. However, Brother and I were more cautious, and refused her kind offer to share. Our mother's horror when she came home from work sometime later and asked where the rat poison was can be imagined. Sister spent the night in hospital, where diligent stomach pumping saved her life. I think that was the last time the local council left unmarked rat poison in anyone's home in an innocent-looking, insecure jam jar.

On Hvar in recent years I have managed to stop the deliveries by putting up notices round my property saying 'Otrov ne hvala' ('Poison, no thanks'), a tactic I recommend to anyone who does not want to be burdened with handling or storing hazardous substances.

My warning notice: No poisons!

Uncontrolled poison distribution is obviously hazardous. Coupled with the fact that poison is not an efficient method of controlling pests, the current policy needs to be reviewed, and practices need to be substantially improved - as a matter of extreme urgency.

  • Exclusive: Study released at Cop28 misused research to underestimate impact of cutting meat eating, say academics

    A flagship UN report on livestock emissions is facing calls for retraction from two key experts it cited who say that the paper “seriously distorted” their work.

    The UN Food and Agriculture Organization (FAO) misused their research to underestimate the potential of reduced meat intake to cut agricultural emissions, according to a letter sent to the FAO by the two academics, which the Guardian has seen.

  • Superfund law requires industries responsible for PFOA and PFOS contamination in water or soil to pay for cleanup

    The Environmental Protection Agency on Friday designated two forever chemicals that have been used in cookware, carpets and firefighting foams as hazardous substances, an action intended to ensure quicker cleanup of the toxic compounds and require industries and others responsible for contamination to pay for their removal.

    Designation as a hazardous substance under the Superfund law does not ban the chemicals, known as PFOA and PFOS. But it requires that release of the chemicals into soil or water be reported to federal, state or tribal officials if it meets or exceeds certain levels. The EPA then may require cleanups to protect public health and recover costs that can reach tens of millions of dollars.

  • Royal Horticultural Society hopes punters will be inspired by Salford winner of pub garden competition

    Pub gardens often feature barren patios, characterless lawns and – worst of all – fake grass.

    Now, the Royal Horticultural Society is asking landlords across the country to plant up their patios, saying they are full of untapped potential for urban green space and wildlife.

  • More than 50% of the planet’s species live in the earth below our feet, but only a fraction have been identified – so far

    Read more: No birdsong, no water in the creek, no beating wings: how a haven for nature fell silent

    The sound of an earthworm is a distinctive rasping and scrunching. Ants sound like the soothing patter of rain. A passing, tunnelling vole makes a noise like a squeaky dog’s toy repeatedly being chewed.

    On a spring day at Rothamsted Research, an agricultural research institution in Hertfordshire, singing skylarks and the M1 motorway are competing for the airways. But the attention here is on the soundscapes underfoot: a rich ecosystem with its own alien sounds. More than half of the planet’s species live in the soil, and we are just starting to tune into what they are up to. Beetle larvae, millipedes, centipedes and woodlice have other sound signatures, and scientists are trying to decipher which sounds come from which creatures.

  • Experts celebrate discovery of secretive and endangered Australasian bittern in recently restored wetlands

    The “bunyip bird” – named after a mythological river-lurking, human-eating monster – is as elusive as its namesake. Also known as the Australasian bittern, it is heard more often than it is seen.

    It means that when bittern expert Geoff Shannon discovered the bird at Tasmania’s recently restored Lagoon of Islands – the first time it had been seen there in 40 years – it was a “very special moment”.

  • Climate campaigners complain of short-termism as country abandons target to cut carbon emissions by 75% by 2030

    Climate campaigners have accused Scottish ministers of being “inept” and “short-termist” after they scrapped Scotland’s target to cut carbon emissions by 75% by 2030.

    Màiri McAllan, the Scottish net zero secretary, confirmed her government had abandoned that target and would also drop legally binding annual targets on reducing carbon emissions, after damning criticism from a UK advisory committee.

    Sean Dooley first started birdwatching as a 10-year-old with a notebook in hand at a place then known as the “Seaford swamp”, a freshwater wetland beside his primary school in Melbourne’s south-east.

    “I was just going out as a kid doing what I loved but recording the birds I saw as I did,” he says. On one of his early visits he met another birdwatcher, Mike Carter, who had been recording birds there and also at nearby Edithvale swamp for some years.

  • Dead and dying shrubs and trees – some of which are found nowhere else on Earth – line more than 1,000km across the state’s south-west

    A couple of weeks ago, Joe Fontaine stood in the middle of one of Western Australia’s eucalypt forests on another hot and dry day that was stripped of the usually raucous backing-track of bird calls.

    “I could hear this scratching-crunching noise coming from the trees,” says Fontaine, a forest ecologist at Perth’s Murdoch University.

  • On the banks of the River Roding, authors explain how they are putting the concept of ‘wild service’ into practice

    It is a call to action that might just be the founding text for a new environmentalism. A forthcoming book by a diverse band of right to roam campaigners offers a radical new vision of how people can repair both the natural world and their broken relationship to it.

    Wild Service: Why Nature Needs You, inspired by the rare wild service tree, calls on communities to develop new relationships with the natural world, combining the hard graft of conservation science with the ceremony, gratitude and fun bound up in festivals, Indigenous traditions and even church services.

  • In 2002, high explosives were laid in oil wells across 20 sq km of forest. The firm has gone but the pentolite remains, despite a court ruling, putting lives and the ecosystem at risk

    Living on the banks of the Bobonaza River, in the Ecuadorian Amazon, the Indigenous communities in Sarayaku have always lived in harmony with nature. The rainforest, says Patricia Gualinga, is a sacred, conscious being.

    So when an Argentinian company was allowed to place a huge amount of high explosive around the rainforest to prospect for oil, the local Kichwa people fought back and eventually took their case to an international court. More than a decade after winning their legal battle, however, the explosives remain strewn around the community’s territory.
