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.

  • Research casts doubt on plans by UK government to offer subsidies for carbon capture attached to the power source

    Burning wood for power generation can be worse for the climate than burning gas, even when the resulting carbon dioxide emissions are captured and stored, new research has shown.

    The findings cast doubt on plans by several governments, including the UK, to offer subsidies or other financial support for carbon capture attached to wood-burning power.

  • Sarah Finch is among six recipients of the Goldman Environmental prize, awarded to honour grassroots activists around the world

    The woman whose campaigning set a legal precedent in the UK that stopped thousands of tonnes of greenhouse gas emissions has been awarded one of the world’s most prestigious environmental prizes alongside five other women from around the globe.

    A supreme court ruling in a case brought by Sarah Finch has been cited in decisions against new oil concessions in the North Sea, the UK’s first new deep coalmine for 30 years and even plans for new large-scale factory farms.

    Iroro Tanshi, a Nigerian conservation ecologist who launched a successful, community-led campaign to protect endangered bats from human induced wildfires;

    Borim Kim, a South Korean activist who won the continent’s first successful youth-led climate litigation, finding her government’s climate policy to be in violation of the rights of future generations;

    Alannah Acaq Hurley, a leader of the Yup’ik Indigenous people led a campaign that stopped what would have been the continent’s largest open-pit mine, in Alaska’s Bristol Bay region;

    Yuvelis Morales Blanco, a youth activist who mobilised others in her Afro-descendant community in Puerto Wilches against two drilling projects, preventing the introduction of commercial fracking into Colombia;

    Theonila Roka Matbob, of Papua New Guinea, whose campaign forced Rio Tinto, the world’s second-largest mining company, to sign an agreement to address devastation caused by its Panguna mine.

  • Conservationists in Denbighshire ‘angry and heartbroken’ after Nant-y-Ffrith site emptied during breeding season

    More than 1,000 toads may have died after a reservoir important to the local ecosystem was drained by a water company, conservationists in north Wales have said.

    Volunteers at Wrexham Toad Patrols help toads returning to the Nant-y-Ffrith reservoir on the Llandegla moors in breeding season, this year assisting 1,500 of the amphibians to cross busy roads to help protect the declining species.

  • Data shows 224,000 new EVs were registered in March, with Norway leading way in terms of switching

    Sales of electric cars soared 51% in continental Europe last month, amid a rise in petrol and diesel costs driven by the Iran war.

    Data shows that 224,000 new electric vehicles (EVs) were registered in March, and 500,000 across the first three months of the year – a 33.5% increase on a year earlier, according to analysis of national sales data in 15 countries by New AutoMotive and E-Mobility Europe, a trade body.

  • As the rising number of vessels in the icy waters increases the risk of environmental disaster, scientists are scrambling to find potential solutions

    Last winter, inside the subarctic Churchill Marine Observatory in Canada, scientists embarked on an experiment they hoped would result in a gamechanging remedy for polluted Arctic waters. They released130 litres of diesel into an ice-covered pool filled with raw seawater pumped in from Hudson Bayand added oil-eating microbes. The technique had been used successfully during the Deepwater Horizon oil spill in the Gulf of Mexico, and the scientists wanted to see if they could break down oil in colder waters.

    The microbes were sluggish in response and the population showed little change after the first three weeks, says Eric Collins, a microbiologist at the University of Manitoba in Winnipeg, who led the project. But that did not last. “When we went back eight weeks later, we saw that there was a big change,” Collins says. “One particular bacterium grew to a very high abundance in the tanks and it was clear that it was feeding on the oil.” But two months is too long to wait should an oil spill occur. Time is of the essence.

  • Zoological Society of London commissions poet laureate for animation to mark its 200th anniversary

    Over its two centuries, acclaimed writers and artists have found inspiration at London zoo, from Edwin Landseer’s Trafalgar Square lions, to AA Milne’s naming “Winnie” after resident bear Winnipeg, and Sylvia Plath’s poem Zoo Keeper’s Wife.

    Plath’s husband, Ted Hughes, who would become poet laureate, worked at the zoo briefly as a dish washer, an experience said to have helped fuel his inspiration for The Thought-Fox.

  • Seville could see 34C this week and parts of Brazil could hit high 30s, while storms forecast in southern Africa

    Over the course of this week, temperatures in Spain are expected to soar well above the seasonal average. Daytime temperatures could reach about 30C in Madrid on Tuesday, 10C above the norm, while Seville may experience 34C, about 9C above its late April average. An area of low pressure situated out in the Atlantic will allow for a south-westerly flow, introducing warm air from north Africa. In addition to this heat, a notable dust plume is expected to travel northwards from the Sahara, covering the skies above Iberia and south-western France, which may lead to some particularly orange or red skies at sunrise and sunset.

    In Brazil, high temperatures are forecast for the states of São Paulo, Paraná, Mato Grosso do Sul and Santa Catarina over the next few days, eventually spreading into Minas Gerais. Here, daytime maximum temperatures are expected to reach the high 30s celsius later in the week, about 5-10C above the seasonal average.

  • Kerbside wheelie bins have been used in Australia since the 1980s but the recycling rate is stuck at 44%. Will another recycling bin make a difference?

    There’s no garbage truck in Kamikatsu.

    Instead, the Japanese town’s 1,400 residents take their waste to the local recycling centre, or “Gomi station”, and sort it themselves into more than 40 different categories.

  • Sarah Finch’s fight against drilling led to a landmark ruling on fossil fuel emissions – and a leading environmental prize

    It started with a notice in the local newspaper and ended with winning one of the world’s most prestigious environmental prizes. In 2010, Sarah Finch was flicking through the local planning notices when one caught her eye: a proposal to drill for oil at Horse Hill in Surrey, just outside Crawley, over the border in West Sussex, 6 miles (10km) from her home.

    Surrey is not the kind of place one expects to find the oil industry. It’s a county of little villages, farms, woods and commuter railway stations. Its semi-rural landscape stretches off towards the horizon in a typically English green patchwork. It is difficult to envision it littered with nodding donkey pumpjacks and gas flares.

  • In Poland, 80,000 people still work in coalmines – the last in the European Union that is fully committed to the energy transition. Once active mines are being converted to other uses, and yet coal is being extracted at record rates worldwide, and with the Iran war pushing up oil and gas prices, some in Poland are asking whether it is worth completely phasing out this fossil fuel

    Coal dust is fine; it seeps into the pores of the skin. That is why a thin black line permanently traces the outline of Rafal Dzuman’s eyes, as if he were wearing makeup. Team leader of the G-2 mining crew, 49-year-old Rafal Dzuman has been descending every day to 700 metres below ground for at least 20 years, at the Murcki-Staszic coalmine in southern Poland. Opened in the mid-17th century and today owned by the Polish giant PGG, the mine sits on the southern outskirts of Katowice, and still extracts about 23,000 tonnes of coal a day.

    Katowice, Poland: Miners exit the lift after working in the coal-mining tunnels at the Murcki-Staszic Mine (PGG Group), located on the southern outskirts of the city. Coal mining began here in 1657; today, the mine’s daily production stands at about 23,000 tonnes
