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.

  • Subsidies awarded to eight new projects help keep UK on track to decarbonise by 2030

    A make-or-break auction for the UK government’s goal to create a clean electricity system by 2030 has awarded subsidy contracts to enough offshore windfarms to power 12m homes.

    In Great Britain’s most competitive auction for renewable subsidies to date, energy companies vied for contracts that guarantee the price for each unit of clean electricity they generate.

  • Data leads scientists to declare 2015 Paris agreement to keep global heating below 1.5C ‘dead in the water’

    Last year was the third hottest on record, scientists have said, with mounting fossil fuel pollution behind “exceptional” temperatures.

    The World Meteorological Organization (WMO) said 2025 had continued a three-year streak of “extraordinary global temperatures” during which surface air temperatures averaged 1.48C above preindustrial levels.

  • Energy company also under pressure from worse oil trading performance and weaker oil prices

    BP has said it expects to write down the value of its struggling green energy business by as much as $5bn (£3.7bn), as it refocuses on fossil fuels under its new chair, Albert Manifold.

    The oil company said the writedowns were mostly related to its gas and low-carbon energy divisions in its “transition businesses”, but added that wiping between $4bn and $5bn off their value would not affect its underlying profits when it reports its full-year results in February.

  • Exclusive: Some scientists say many detections are most likely error, with one high-profile study called a ‘joke’

    High-profile studies reporting the presence of microplastics throughout the human body have been thrown into doubt by scientists who say the discoveries are probably the result of contamination and false positives. One chemist called the concerns “a bombshell”.

    Studies claiming to have revealed micro and nanoplastics in the brain, testes, placentas, arteries and elsewhere were reported by media across the world, including the Guardian. There is no doubt that plastic pollution of the natural world is ubiquitous, and present in the food and drink we consume and the air we breathe. But the health damage potentially caused by microplastics and the chemicals they contain is unclear, and an explosion of research has taken off in this area in recent years.

  • Waresley, Cambridgeshire:In a near-freezing lake, I’m treated to an up-close view of one of my favourite birds

    The spring-fed lake is a picture of tranquillity this morning. On the far side, ivy-clad trees touch trunks with their watery counterparts, creating an image of a child’s mirror painting folded along the shoreline. Only the soft blurring of branches distinguishes reflection from reality.

    The scene might look serene, but I must focus on my breathing to stay calm as I lower myself slowly into the water, which has chilled to a wintry 6C. I started cold water swimming last month, hoping it would help relieve the chronic pain caused by adenomyosis. It’s only my fourth session, and I’m wondering if I have the confidence to swim across the lifeguarded lake when a quick movement on the water catches my attention. I spot a dumpy ball of fluff that isn’t there.

  • Seven out of 10 targets have little likelihood of being met by 2030, Office for Environmental Protection says

    The government will not meet its targets to save wildlife in England and is failing on almost all environmental measures, the Office for Environmental Protection watchdog has said.

    In a damning report, the OEP has found that seven of the 10 targets set in the Environment Act 2021 have little likelihood of being met by 2030, which is the deadline set in law.

  • For Hannah Thorogood, a first-generation Lincolnshire farmer, grazing her sheep on solar land gave her a leg-up in the industry

    On a blustery Lincolnshire morning, Hannah Thorogood paused between two ranks of solar panels. Her sheep nosedived into the grass under their shelter and began to graze.

    “When I first started out, 18 acres and 20 sheep was as much as I could afford,” said the first-generation farmer. “Now, because I can graze this land for free, I have 250 acres and over 200 sheep. Solar grazing has given me a massive leg-up.”

  • Britain’s winter thrushes, the swallows and swifts of the season, were strangely absent until recently

    Just as swallows and swifts are the constant sight and sound of spring and summer, so our two winter thrushes – fieldfares and redwings – are usually ever-present during the autumn and winter months.

    Last autumn, however, the fields and hedgerows around my Somerset home were unusually devoid of these birds, while their favourite food – the hawthorn’s bright scarlet berries – remained uneaten.

  • Professional mermaids risk hypothermia, seasickness and the cling of skin-tight silicone, but the reward is becoming an ‘ocean ambassador’ – and a bit more colour in the world

    Propelled by a shimmering silicon tail, Katrin Gray spins underwater, blowing kisses to the audience as her long, copper hair floats around her face. Her seemingly effortless movement is anything but – a professional mermaid’s free diving and performance skills require training, practice and total concentration.

    Mermaiding has become a global cottage industry, with pageants, conventions, retreats and meet-ups, where people gather in “pods” to practise their dolphin kicks. Makers create bespoke tail flukes, bejewelled bras, mermaid hair and even prosthetic gills for professional and hobbyist “seasters”. There is even a Netflix reality series called MerPeople, which documents the occasionally perilous journey of several aspiring professional merfolk. “No dead mermaids” is the motto of one business featured.
