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.

  • An ambitious ‘refaunation’ project is bringing the much-loved birds and other lost species back to the city’s national park

    Images of the iconic blue-and-yellow macaw can be spotted all over Rio de Janeiro. Yet the real thing has been seen so rarely in the Brazilian city that some wondered if it ever really existed there at all.

    The French explorer Jean de Léry first described an abundance of the giant, colourful parrots around Indigenous tribes in the 16th century, and the Austrian naturalist Johann Natterer sighted theAra araraunain the city in 1818.

  • Tim Friede put his ‘ass on the line’ to help stop snakebite deaths – whose numbers appear to be rising amid the climate crisis

    As we overheat and degrade our planet, more people are set to come into contact, sometimes fatally, with venomous snakes. One man hopes to provide an unusual solution to this, after subjecting himself to 200 intentional snakebites to his body.

    For nearly 20 years, Tim Friede, 58, allowed some of the most lethal snakes in the world to bite him so he could build up an immunity that could one day be developed into a universal antivenom.

  • Senior climate figures warn North Sea drilling would encourage fossil fuel exploitation by developing countries

    Opening new oil and gas fields in the North Sea would “send a shock wave around the world”, imperilling international climate targets, undermining the UK’s climate leadership and encouraging developing countries to exploit their own fossil fuel reserves, experts have warned.

    The UK government is under stiff pressure from the oil industry, the Conservatives, Nigel Farage’s Reform UK party, some trade unions and parts of the Treasury to give the green light to new oil and gas fields, despite clear evidence that doing so would not cut prices and would have almost no effect on imports.

  • Use of glyphosate has risen 10-fold in 30 years, raising fears for public health

    It was Scottish farmers in the 1980s who pioneered the practice of spraying glyphosate on their wheat just before harvest. Struggling in the damp glens to get their crop to dry evenly, they came up with the idea of accelerating the process by killing it a week or two before harvesting.

    Glyphosate, then a revolutionary herbicide that killed everything plant-based but spared animal life, seemed perfect for the job. Soon the practice spread to wetter, colder agricultural regions around the world.

  • Cardiff: Robin then blue tit, siskin then goldfinch … I love this ritual, but I’m persuaded that it deserves careful thought

    I’ve been away from my bird feeder for months and, on my return, one of my priorities is to restock it. This has become a ritual, and I feel great joy in observing the strict order in which the birds arrive.

    I sit down and wait for the local population to remember my table and spread the word. It’s not long before they come in sequence, no less predictable than court etiquette. The first to venture for sunflower seeds is the robin. The blue tit, in a whirr of wings, comes a close second. These two act as food tasters. Other species, out of sight, watch intently to see if the daring survive. They do, so dunnocks arrive, then a pair of chaffinches, picking up spilt seeds from the ground.

  • Sandra Laville has been reporting on England’s sewage crisis for years. She answered your questions on the water privatisation scandal.

    Guardian environment correspondent Sandra Laville’s reporting on the sewage crisis in English water has helped to expose a scandal of privatisation that has created a swell of fury across the political divide.

    Sandra has now finished answering your questions. Read the Q&A below.

    The government has put the cost of renationalising water at £100bn. But this is a disputed figure. Academics working with the People’s Commission on the Water Sector say this figure is ‘serious scaremongering created on biased evidence’ which was paid for by water companies. It is based on the Regulatory Capital Value of companies as determined by Ofwat, not the” true and fair value in law”, which reflects losses from market failures, like the cost of pollution or the monopoly profits taken by shareholders and banks.

    The route to renationalisation could come via the system set up legally when the companies were privatised. Under the law companies can be put into special administration if they are unable to pay debts, if they breach licence obligations, such as on sewage pollution, or failing to supply water, and if it is considered in the public interest to do so. Special administration is a form of temporary renationalisation.

    This is the million dollar question! While tackling separation across the whole network at once is considered too disruptive and costly, particularly in urban environments, the chartered institute of water and environmental management says moving towards separated systems is their key focus to address urban pollution and storm water sewage releases. New developments, for example, are now mandated to have separate pipes for foul wastewater and surface water run off.

    They also want to see the increased use of sustainable drainage systems like water butts, and storage basins for existing properties, to reduce the amount of runoff into the system. Keeping gardens rather than paving them over, and creating so called sponge cities is also key to tackling pollution.

    The UK was described as the dirty man of Europe back in the 70s and 80s, due to levels of pollution. For example in coastal towns there were no water treatment plants to treat sewage, raw sewage was just pumped and dumped into the sea. It was only when the EU directives came in that the clean up began. Chief amongst these was the Urban Wastewater directive, the Water Framework directive, and the Bathing Water directive.

    Since leaving the EU there have been fears that these pieces of legislation could be watered down. James Bevan, as CEO of the Environment Agency, talked about changing the Water Framework Directive, essentially to make it easier for rivers to pass tests for chemical and biological health. Currently no river is rated as in good overall health under the WFD where rivers have to pass both chemical and biological health tests.

  • Like so many flying insects, these essential pollinators are suffering because of habitat loss and the overuse of chemicals. Here’s how to give them a healthier, happier home

    We know about honeybees and bumblebees, but most of the UK’s bees are neither: they’re solitary bees, loners who come in a dizzying range of sizes, colours and varieties – more than 240 species. Have you heard, for instance, of the hairy-footed flower bee? “They’re one of the first bees to emerge each year,” says Laura Larkin, the chief conservation officer at Buglife. “The males have got fantastic little fluffy bits on their feet.”

    How about leaf-cutter bees, which chomp “a perfectly circular hole” out of leaves to build their nests? Or bright-orange tawny mining bees, wool-carder bees, ivy bees? “There are so many of them and I’m still learning,” says Kate Bradbury, a wildlife gardener, writer, bee lover and the author of One Garden Against the World. “They’re just great – there’s a solitary bee for every occasion.”

  • Guardian Australia tours problematic Malabar wastewater plant where some accumulated fats, oils and grease can’t be accessed – let alone cleared

    “This,” says Fiona Copeman, the hub manager of the Malabar wastewater treatment plant, “is what you would call our four-bus area.”

    Copeland is gesturing to a model of the plant on a table inside the facility itself. She’s referring to a 300 cubic metre underground chamber that houses, as Guardian Australia revealed in January, a “fatberg the size of four buses that likely birthed poo balls that closed Sydney beaches”.

  • The birds – not native to the South Australian island – have covered a school in faeces, torn up infrastructure and damaged crops

    Thousands of little corellas that have been terrorising the inhabitants of Kangaroo Island have been culled but it won’t be enough to fix the problem, authorities say.

    The birds, which are not native to the island, have covered a local school in faeces, torn up infrastructure, damaged crops and caused mental distress to residents with their screeching.
