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.

  • Under Anne Hidalgo – mayor for 12 years until last week – the French capital added bike lanes, cut traffic and reclaimed public space, but not without resistance

    When Corentin Roudaut moved to Paris 10 years ago, he was too scared to cycle. The IT developer had biked everywhere as a student in Rennes but felt overwhelmed by the bustling French capital. Cars were everywhere. Cyclists had almost no protection.

    But once authorities carved out space for a segregated bike lane on Boulevard Voltaire near his home in the 11th arrondissement, Roudaut returned to the two-wheel commute and did not look back.

  • Tebay, Cumbria: A planned reintroduction of these apex predators has got us upland farmers worried. We’re still not convinced they won’t harm our flocks

    The years seem to be coming around very quickly – this will be my ninth spring at this farm. As the days get longer and the grass begins to grow, my mind turns to lambing. We have a short growing season here, so we plan for lambing to start mid-April, hoping the grass will have started growing by then. The tiny Ouessant sheep, which have to lamb indoors due to predation, started lambing on April Fools’ Day.

    Last year I put a large group of Ouessants outside to graze on the Roman fort when they were four days old, and they disappeared without a trace – 13 lambs lost. It wasn’t a fox or a badger, as we know what a predated carcass looks like, and it wasn’t the mink that had been killing hens, as that was leaving dead bodies.

  • Exclusive: research finds Jackdaw field would provide only about 2% of current demand, and Rosebank only 1%

    Opening major new fields in the North Sea would make almost no difference to the UK’s reliance on gas imports, research has shown.

    The Jackdaw field, one of the largest unexploited gasfields in the North Sea, would displace only 2% of the UK’s current imports of gas, which would leave the UK still almost entirely dependent on supplies from Norway and a few other sources.

  • The US has invoked national security to remove protections for the endangered cetacean, of which only about 50 are left

    Since before modern humans existed Rice’s whales have been diving to the depths of the ocean to gorge on fat-rich fish while growing to leviathan proportions, their bodies spanning the length of a bus and weighing as much as as six elephants.

    Unfortunately for these grand creatures, their only home became a patch of the Gulf of Mexico that the oil and gas industry, much later, became highly interested in for drilling. Only about 50 of these baleen whales still exist on Earth, surrounded by clanging aquatic highways of boats and shifting drilling infrastructure.

  • In turbulent times, experts recommend building up a store of food if possible – focusing on long-life, no-cook items

    People should have an emergency stockpile of food in their homes in case conflicts, extreme weather or cyber-attacks shut down supplies, leading UK experts have told the Guardian.

    In an ever more turbulent world, they say it is essential to choose long-life items that can be eaten without cooking – think tinned beans, vegetables and fish, rice crackers, and oats that can be soaked. But it is also important to choose items you actually like to eat, and some treats such as chocolate or crisps to keep your spirits up. You will also need water – lots of it – not just to drink but for washing too.

  • Researchers are weaving Native practices with western methods to revive ecosystems and reclaim food sovereignty

    “I’m a glorified clam counter.”

    So said Marco Hatch, a marine ecologist at Western Washington University and an enrolled member of the Samish Indian Nation. Hatch has been conducting surveys of mollusks growing in and around clam gardens in the Pacific north-west, as he collaborates with seven Indigenous communities to build or rebuild these rock-walled, terraced beaches once created and tended by their ancestors.

  • Citizen science data reveals early flowering, nesting and insect activity as global heating accelerate seasonal change

    Bluebells are flowering, swallows are returning and orange-tip butterflies are flying in what could become Britain’s earliest recorded spring.

    Records for early spring occurrences are being smashed as 2026 looks to be the earliest this century for frogspawn laying, blackbirds nesting, brimstone butterflies emerging and hazel flowering, according to Nature’s Calendar, which has logged citizen science records of seasonal change since 2000.

  • Stock runs low as oil crunch increases enthusiasm for electric vehicles

    When a used vehicle rolls into a car yard, the usual trajectory for its price tag is down if it lingers too long.

    That is the (almost) iron law of the secondhand market – until the oil crisis hit and dealers started raising asking prices for used electric vehicles.

  • Scientists estimate the endangered bird’s population has slumped to about 750. But the logging agency responsible for clearing its habitat said it acted lawfully

    They are sounds from a section of forest that no longer exists. In December and January, scientists for the Bob Brown Foundation captured the call of the swift parrot, a critically endangered migratory species. The environment campaign group says it was recorded in an area marked for clear-felling in the Wielangta forest in Tasmania’s south-east.

    The foundation’s Dr Charley Gros said the vocal mark of the world’s fastest parrot was unmistakable. “It’s a tiny bird but has a very loud call,” he said. “It’s very sharp and quick and fast. You can’t confuse it with something else.”

  • Hamburg shop set up in tribute to aspiring pastry chef becomes ‘happy’ pilgrimage site for grieving parents

    Johanna Orth was a fun-loving, determined little girl and later a purpose-driven young woman who revelled in making a creative mess in the kitchen. Her parents, Inka and Ralph, chuckle quietly as they remember the stacks of batter-covered bowls, spatulas and whisks repeatedly left in the sink.

    With time, Johanna’s cakes and pastries grew more sophisticated and elaborate, guided by her grandmother, Marlies, who was also a talented baker. Marlies’ own ambition of opening a cafe one day had been thwarted by the demands of motherhood and postwar Germany’s rigid gender roles.
