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.

  • Rafael Moreno, whose company has opened demo plant in Brazil, says market is ‘nervous’ as Trump-Xi summit looms

    The head of a mining company hoping to supply the EU with rare earths in two years’ time has said it is “paramount” to end China’s stranglehold on the supply of the raw materials used in everything from cars to wind turbines and military jets.

    As Donald Trump and China’s president, Xi Jinping, prepare to meet on Thursday in their second summit of the year, Rafael Moreno said it was also “imperative” that they do a deal for Beijing to ease up, once again, on its threat to ban exports of rare earths.

  • Amid record-shattering heatwaves and popular demand for climate action, why are politicians often timid or in denial?

    It was, according to the European Commission president, Ursula von der Leyen, the “summer of truth”. Climate chaos ripped through Europe and the northern hemisphere, sending heat records tumbling, scorching crops in the fields, burning forests, emptying rivers and reservoirs, warping train tracks, melting roads and killing about 35,000 people in Europe alone.

    The EU has estimated the damage at about €180bn, and the full bill is yet to arrive: harvests have been depleted, which will probably raise food price inflation, and expensive repairs to infrastructure have only just begun.

  • Much of the UK is still officially in drought after its hottest summer on record, but grasslands are slowly recovering their colour

    The landscapes of southern England and Wales are slowly regaining their colour after this summer’s extreme heat.

    The UK’s hottest summer on record left the south of the country dried out and brown, making the impact of the drought particularly visual.

  • After summer’s heatwaves, prepare for winter of storms and heavy rain, with millions of UK homes at risk of flooding

    The accelerating climate crisis and this year’s record-breaking El Niño mean that, although the summer’s heatwaves are still fresh in the memory, households in the UK are already being told to prepare for a potentially destructive winter of storms and heavy rain – leaving millions of homes at risk of flooding.

    Government action is needed to improve flood defences and build reliance on a national and regional level. But with the UK’s flood season just weeks away, the Guardian spoke to experts to find out what action communities and individuals can take to make their neighbourhoods and homes more resilient, from self-closing airbricks to deflated children’s footballs.

  • The world is suddenly full of webs and hairy legs. But why? And what do they belong to? Meet the spiders you’re most likely to encounter, from cardinals to false wolves

    Summer is at an end, and suddenly spiders seem to be everywhere – in your house, in your garden, in your hair. Fresh webs hang from doorways, walls, shrubs and fence posts, creating invisible obstacle courses. Where do all these spiders come from, what kind are they and what, if anything, should we do about them?

    The short answer to the question “Why are there so many more spiders at this time of year?” is: there aren’t. They are just more obvious. Dave Clarke, an ectotherm (“cold-blooded” animal) specialist at the Zoological Society of London, says: “There are more spiders around in the spring, because that’s when they hatch from their egg sacs, and there are hundreds of babies in each egg sac. But they’re small and not very obvious. They grow up during the summer and, at this time of year, they reach their maximum size.” Their webs are also correspondingly larger.

  • Stanhope, Weardale: I’ve realised in that time that beauty and fascination can lie in the most mundane of plants – in this case, broad-leaved dock

    After another exceptionally dry summer, there’s a nagging question lurking at the back of naturalists’ minds: which species will be the winners and losers in our evolving climate?

    Throughout summer’s heatwaves and drought, I watched a dense stand of broad-leaved docks, Rumex obtusifolius, thrive while surrounding fields turned the colour of bleached straw. They have promising credentials as drought survivors, thanks to a deep taproot, fast, early spring growth and a long-lasting dormant seed bank in the soil.

  • Northern Roots is launching Britain’s biggest urban farm and eco-park, in an effort to boost people’s health and wellbeing

    Standing in the open green space of Northern Roots, it is hard to imagine the landscape as it once was.

    Two cotton mills, two coalmines and an industrial railway once occupied this 65-hectare (160-acre) site in Oldham, Greater Manchester. Later, about 24 hectares became a tip, with much of the space left to nature.

  • People are increasingly crossing paths with the wild animals as homes ring the outskirts of forests, sparking a new era of coexistence

    Every year, as summer draws to a close and fall begins, California’s bears get hungry.

    Black bears have long roamed the state, hunting for acorns, ants and pine nuts by the bucketload to pack on calories before hibernation. But increasingly, for every berry and root, there’s an even greater temptation: our trash and the detritus of human existence.

  • Trump says he digs coal – but pneumoconiosis cases are at a 50-year high, and sick miners are mired in benefit delays

    For 38 years, Josh Armes worked as a coal miner in West Virginia and Virginia.

    After retirement, Armes, 74, of Grundy, Virginia, was diagnosed with black lung disease, medically known as coal workers’ pneumoconiosis (CWP), caused by breathing in coal dust over long periods, which irreversibly damages the lungs.

  • The English have been eating oysters for thousands of years, and advocates say they are an important indicator of the health of coastal waters

    Beneath bunting in the middle of Mayfair, there was a feverish atmosphere as the finals of potentially the poshest sport in England began: oyster shucking, judged by actor Stanley Tucci.

    “The secret is not being scared of stabbing yourself in the hand,” says Quincy CoulterYoung from Rocks Oysters, one of the fastest oyster shuckers in the country.
