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.

  • Unless urgent action is taken life will be fundamentally altered for the ancient communities who live on its banks

    As a leader of one of the oldest gnostic religions in the world, Sheikh Nidham Kreidi al-Sabahi must use only water taken from a flowing river, even for drinking.

    The 68-year-old has a long grey beard hanging over his simple tan robe and a white cap covering his equally long hair, which sheikhs are forbidden from cutting. He says he has never got ill from drinking water from the Tigris River and believes that as long as the water is flowing, it is clean. But the truth is that soon it may not be flowing at all.

  • Ten years after I first followed the proposed route, I retraced my steps to see what life was like along the world’s most expensive, heavily delayed railway line

    Ten years ago, I walked the route of HS2, the 140-mile railway proposed to run from London to Birmingham, to discover what lay in its path. Nothing had actually been constructed of this, supposedly the first phase of a high-speed line going north. The only trace was the furtive ecological consultants mapping newts and bats and the train’s looming presence in the minds of those who lived along the route. For many, it was a Westminster vanity project, symbolising a country run against the interests of the many to line the pockets of the few. People whose homes were under threat of demolitionwere petitioning parliament, campaigning for more tunnels or hoping the project would collapse before their farms, paddocks and ancient woodlands were wiped out.

    The line, we were told a decade ago, would be completed by 2026. Like many of the early claims about the longest railway to be built in Britain since the Victorian era, that fact no longer stands. The fast train is running – very – late. The official finish date of 2033 was recently revised upwards. “The best guess is that it will begin with a ‘4’ when you can catch a train,” one well-informed observer told me. There’s similar uncertainty about its cost, but one thing is sure: it is catastrophically over budget. When complete, HS2 will almost certainly be the most expensive railway in the world. Nearly 20 years ago, HS1, the line from the Channel tunnel to St Pancras, was completed on time and on budget for £51m per mile (£87m in today’s prices). It was criticised for being twice as expensive as a high-speed route constructed in France. HS2 may cost almost £1bn per mile.

  • The oil and gas industry must be legally bound to cut methane emissions. With climate tipping points approaching, time is running out

    • Mia Mottley is the prime minister of Barbados

    The timing is brutal. Just as the world celebrates the 10th anniversary of the adoption of the Paris climate agreement this month, new evidence shows that the world is crashing through the main defence that was constructed against climate catastrophe.

    The three-year temperature average is – for the first time – set to exceed the Paris guardrail of 1.5C above preindustrial levels. According to the Copernicus Climate Change Service, 2025 will join 2023 and 2024 as the three warmest since the Industrial Revolution, reflecting the accelerating pace of the climate crisis.

  • Hogshaw, Derbyshire: They’re in our paintings, in our folklore. A little opportunistic planting and I’ve got them in my garden

    As I cleared our garden of dead vegetation, including many old teasels, I realised that the latter were still shedding seeds and luring goldfinches to them. Not wishing to deprive winter birds of food, or myself of opportunity, I planted the stalks in a single grove, and set up a mobile hide. Within minutes, a kind of magic unfolded. Sulphur wings twittered as old plants swayed with their featherweight burdens and the pointed pink beaks jabbed relentlessly for food.

    Of all European birds, goldfinches are surely those best able to illustrate the survival of magical thinking in our world. Throughout the middle ages and the Renaissance, more than 300 artists across 486 works – including those of Leonardo, Raphael and Michelangelo – painted Madonna and Child images with goldfinches secreted in them.

  • Climate crisis forecast to wipe out thousands of glaciers a year globally, threatening water supplies and cultural heritage

    Glaciers in the European Alps are likely to reach their peak rate of extinction in only eight years, according to a study, with more than 100 due to melt away permanently by 2033. Glaciers in the western US and Canada are forecast to reach their peak year of loss less than a decade later, with more than 800 disappearing each year by then.

    The melting of glaciers driven by human-caused global heating is one of the clearest signs of the climate crisis. Communities around the world have already held funeral ceremonies for lost glaciers, and a Global Glacier Casualty List records the names and histories of those that have vanished.

  • Only 10,000 out of economic bloc’s 6m trucks are electric and are more likely to be operating on short routes

    The chances of the European trucking industry hitting zero emissions targets are “dire”, an industry body has warned, as it emerged that only a tiny amount of lorries delivering goods in the EU are electric.

    Speaking as the European Commission prepares to water down electric car targets, the boss of the association for commercial vehicles called on the commission to commit to an urgent review of the sector, tackling problems including a lack of public charging points, a lack of tax breaks for trucks and high energy costs.

  • RHS predicts big shift in gardening habits as green-fingered Britons adapt to climate breakdown

    Bouquets of cut flowers will be swapped for tabletop vegetable plants next year, the Royal Horticultural Society has said, as the UK charity announces its top plant trend predictions for 2026.

    Mini-planters of aubergines, chillies, peppers and tomatoes will be displayed in homes instead of flowers, as breeders develop dwarf varieties that are decorative and capable of supplementing the weekly shop, the RHS says.

  • Despite billions in investment and backing from the federal government, carbon capture and storage technology ‘should be in no way treated as a climate solution’, critics say

    The US energy company Chevron describes it as the world’s largest industrial carbon dioxide injection project of its kind. But it has a problem. It still isn’t working as promised and the results are getting worse.

    The $3bn Gorgon carbon capture and storage (CCS) development, on Barrow Island off Western Australia’s Pilbara coast, was supposed to start operating in 2016, backed by $60m in federal government funding. Chevron and its partners in the project, including Shell and ExxonMobil, said it would capture up to 4m tonnes of carbon dioxide (CO2) from an underwater gas field each year and inject it in a reservoir more than 2km beneath the island.

  • Jessica O’Bryan puts the $60,000 Musso EV through its paces in suburban Sydney and finds some pluses, some minuses – but no charging points

    When I am handed the keys to Australia’s first affordable fully electric ute, to say I feel nervous is an understatement.

    I’ve been driving a 2014 Volkswagen Polo for the past four years, and before that, a Holden Astra that was older than me.

  • The watershed summit in 2015 was far from perfect, but its impact so far has been significant and measurable

    Ten years on from the historic Paris climate summit, which ended with the world’s first and only global agreement to curb greenhouse gas emissions, it is easy to dwell on its failures. But the successes go less remarked.

    Renewable energy smashed records last year, growing by 15% and accounting for more than 90% of all new power generation capacity. Investment in clean energy topped $2tn, outstripping that into fossil fuels by two to one.
