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.

  • About 68,000 households lose electricity in northern France as Italy issues red alerts for 16 cities

    Grahame Madge, a Met Office spokesperson, said the agency is forecasting 39C as a headline maximum temperature on Thursday in the UK, most likely for somewhere in London or the south-east.

    “It is possible we could see temperatures higher than the 39C if the final values are at the upper end of our narrow range,” he said, according to the Press Association.

  • Analysis shows cars in Europe have grown longer, taller and wider every year since 2000

    Cars have grown 1.2cm longer, 0.5cm taller and 0.5cm wider each year on average since 2000, analysis of new vehicles sold in Europe has found, in what green groups call “relentless carspreading”.

    The increase in size, which leaves people more likely to be killed in a crash and increases emissions that hurt lungs and heat the planet, has progressed at a roughly steady rate for two and half decades even as family sizes have fallen, the campaign group Transport & Environment (T&E) found.

  • Matriarchal groups in east and west exhibit distinct click patterns, used to form social structures

    From “Howdy” to “G’day”, English – like other languages – is rich in dialects. Now researchers have found sperm whales on different sides of the Mediterranean show similar variations in their vocalisations.

    Sperm whales communicate vocally using sequences of short clicks called codas. However, the rhythmic pattern of these clicks, known as the dialect, can differ between different matriarchal groups.

  • UK regulator has increased its scrutiny of fashion retailers over potentially misleading environmental statements

    Ads for Calvin Klein, Adidas and Uniqlo promoting “recycled” clothing and shoes have been banned by the UK watchdog after the advertisers were unable to prove their green claims.

    Each of the fashion companies ran paid-for Google ads, with Adidas promoting “recycled running shoes”, Calvin Klein “recycled” tops for women, and Uniqlo advertised fleece coats and jackets made from “recycled materials”.

    Weakening the UK’s net zero policy would disrupt business and damage the economy, the UK’s chief climate adviser has warned.

    Nigel Topping, chair of the Climate Change Committee (CCC), said: “The U-turns are really damaging to inward investor confidence. If we really want to grow the economy, then investing and getting good at building stuff is essential.”

  • Horsey Island, Hamford Water, Essex: It’s the setting for one of Arthur Ransome’s wonderful books, and today it’s farmed by a single family with innovation and care

    You need two permissions to access Horsey Island: one from the farmer, the second from the tide, which offers a four-hour window in every 12 when the causeway can be crossed. It takes me 20 minutes to pick my way over, wading the deeper sections where spindly marker posts show the way. It’s a disconcerting place to loiter. In places the mud either side is a foot higher than the track, and riddled with tiny creeks in which streamers of sea forsaken by the tide rush along invisible gradients. The whole expanse fizzes and trickles as air and water try to escape from the mud and heaps of bladderwrack.

    The dreamlike quality is enhanced by a feeling I’ve been here before, which, in a way, I have. The island is the setting for Secret Water, part of Arthur Ransome’s Swallows and Amazons series, which I loved as a child and revisited ad nauseam during a phase when my son read almost nothing else. It is here on the River Wade that two of the adventurous children are trapped by rising water and rescued by a marsh-wise local boy nicknamed the Mastodon, because of the enormous round tracks left by his “splatchers” – like snowshoes for traversing mud.

  • Photographer Shane Hynan explores the tension between the central role peat bogs play in Irish life and their wider environmental impact

    “You can read Ireland’s history in the boglands. They hold millennia in their layers,” says photographer Shane Hynan of his project, Beofhód (meaningBeneath in English).

    The boglands, known as portachs in Irish, cover roughly 1.2m to 1.5m hectares or about 14% to 17% of the country’s total land area. The raised bogs of the Irish Midlands are made of peat that forms at a rate of 1mm a year (0.04in) in low-lying, poorly drained basins or former lakes. As the historical geographer Kevin Whelan observes in the Atlas of the Irish Rural Landscape, “the bog has been etched as deeply into the human as into the physical record in Ireland – to an extent unrivalled elsewhere.”

  • Researchers assessed likelihood gas was produced during creation of Alps, Pyrenees and Baetic mountains

    Hydrogen gas is anticipated to play a central role in phasing out fossil fuels, particularly in industries that are proving more challenging to decarbonise, such as chemical production, shipping and steelmaking. But producing hydrogen synthetically is energy intensive and costly. In order for the hydrogen economy to take off, we need to find reliable natural sources of this gas. Could it be hidden in the mountains?

    Researchers used plate tectonic simulations to investigate the Pyrenees, Alps and Baetic mountain ranges to assess if their mountain-building processes were likely to have resulted in hydrogen being produced and stored. Their findings, published in the Journal of Geophysical Research: Solid Earth, showed that the Alps and Pyrenees could be strong natural hydrogen exploration sites.

  • As hot weather becomes more common, companies and homeowners are coming up with innovative ways to keep properties cool

    When graphic designer Marc Alabaster had a new set of glass doors installed at his West Sussex home eight years ago, he soon realised how they magnified the heat of the afternoon sun.

    “The kitchen was 40-plus degrees,” he said. Then he went on holiday to Spain and saw an apartment building wrapped in louvre-like rows of angled fins or blades that shaded the external walls against the sun.

  • The cost of the traditional takeaway has doubled since 2019, and more outlets are trying to tempt customers with cheaper options such as coley, pollack and hake

    In late April, visitors to Harbour Lights in Falmouth, Cornwall, may have raised an eyebrow. The fish and chip shop was in the midst of a “cod-free week”, its owners having removed cod from its menu entirely.

    It was the second time owner Pete Fraser had undertaken the experiment, 15 years after the first. He also removed cod from his shops in Penzance and Helston, replacing it with coley, pollack, hake and hoki. The result was very different. “Some of the feedback we had, which certainly wasn’t what we got when we ran it years ago, is ‘Can you repeat this?’ Before, it was like, ‘Have you guys lost your head’?”
