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.

  • Britain’s toads have begun their spring migration, putting them at even greater risk than usual. Here’s how – and why – we should look after them

    There’s a touch of old magic about toads, those shapeshifters of myth, superstition and folklore. Charismatic creatures with the pleasing Latin binomial bufo bufo, common toads have astonishing copper- or gold-coloured eyes and rugged, textured skin. “People say they look warty, which I’ve always thought is a bit unfair,” says Dr Silviu Petrovan, a conservationist and toad population researcher.

    More prosaically, toads are great for your garden. “We say toads are a gardener’s best friend, because they eat all the pests,” says Jenny Tse-Leon, the head of conservation and impact at the British amphibian charity Froglife. Their spring migration is a dramatic event, during which hundreds of thousands of animals travel back to their ancestral breeding ponds. “Like the wildebeest of the Serengeti,” says Tse-Leon. “They’re just a lot smaller than wildebeest.” The males “piggyback” on potential partners: “You see them riding on the female’s back to get a lift to the pond.”

  • Early spring sightings show colourful insect is a resident species for first time in decades, says conservation charity

    The large tortoiseshell – an elusive and enigmatic butterfly that became extinct in Britain in the last century – is a UK resident species once again, with a flurry of early spring sightings.

    Britain’s list of native butterflies has increased to 60 with the return of the insect after individuals emerged from hibernation in woodlands in Kent, Sussex, Hampshire, Dorset, Cornwall and the Isle of Wight.

  • Jessika Roswall cites Poland and Finland, which have made border areas near Russia or its allies ‘more hostile’ to cross

    Countries should look to rewild their land borders as a deterrence to invasion and build up other geographical defences to attack, Europe’s environment chief has said.

    Jessika Roswall, the EU’s commissioner for the environment, water resilience and a competitive circular economy, said nature should be used to improve national security. “Investing in nature and using nature as a natural border control is necessary, and actually increases biodiversity. It’s a win-win,” she said.

  • A Guardian investigation with DeSmog reveals thousands of tonnes of fish are illegally turned into fishmeal and oil off the coast of Guinea-Bissau

    The only ice factory on Bubaque, an island in west Africa’s Guinea-Bissau, is out of service. Local fishers, such as Pedro Luis Pereira, are forced to source ice from factories on the mainland, about 70km away – a six-hour round trip by boat.

    “The machines have been broken for months,” Pereira says, as he pulls in his nets on the shore of the island inside the protected Bijagós archipelago. “We’ve alerted the ministry of fisheries, but so far, no one has come to fix them.”

  • Lower Ouseburn, Newcastle upon Tyne: Under boardwalks, in concrete, on window ledges, seeds borne by water and carried on feet survive

    The Ouseburn slides glassily, reflecting clouds, as it moves towards the Tyne. These lower reaches are tidal, once used for loading coal barges, here in the industrial heart of Newcastle. From glassworks, bottleworks, potteries and flax mills, the area is now transformed into waterside cafes, bars and housing. The burn flows through a variety of habitats: a wooded dene beneath a soaring viaduct, past stables, a farm and converted factories, exposed mud and ivied ruins, an evolving cityscape, its plants often overlooked.

    We study the ground while joggers and prams go past and progress is slow; there’s so much life here in the footpath margins. James Common has researched the city’s plants for six years and his book Urban Flora of Newcastle and North Tyneside is published on Monday. He found the Lower Ouseburn to be the fifth most diverse 1km square of the 188 he covered, the others being nature reserves and the Victorian park of Jesmond Dene. This vibrancy is the result of movement, of people and industry, animals and ships’ ballast, seeds borne by the river or carried on feet.

  • Private equity group EQT to take 42% stake as supplier faces scrutiny over environmental record and CEO’s pay

    A leading European investor will pump fresh funding into Yorkshire Water including helping to cover a £600m loan, despite recent heavy sewage fines and a scandal over executive pay at the utility company.

    EQT, a Swedish private equity group, said on Monday it would take a 42% stake in Kelda Holdings, the Jersey-registered parent company of Yorkshire Water, which has 5.7 million customers across Yorkshire and parts of the East Midlands and Lincolnshire.

  • Self-styled ‘punk’ beer company bought land in 2020, pledging to plant Scotland’s ‘biggest ever forest’

    The self-styled “punk” beer company BrewDog sold its Highland estate for a knockdown price after abandoning its efforts to plant Scotland’s “biggest ever forest” there.

    BrewDog’s co-founder James Watt claimed its Lost Forest project at Kinrara in the Cairngorms national park would cover a “staggering area” and capture tens of millions of tonnes of CO2 during its lifetime.

  • Like Stonehenge, the Australian coastal landmark is first seen from a busy highway – and locals warn charging a fee for safe viewing could make existing congestion worse

    How much is a view worth? The Victorian public is asking itself that question after the state government announced on Monday that it would impose visitor fees on one of its most spectacular landmarks, the Twelve Apostles.

    Bookings would be required and a fee payable for parking and access to the $126m Twelve Apostles Visitor Centre, the gateway to the main viewing decks for the famous sea stacks – columns of remnant rock from the eroded Victorian coastline, visible along the winding, 240km-long Great Ocean Road.

  • zack mennell made a costume out of nappies and waded into filthy waterways saying: ‘I’m going to be the parasite.’ The performance artist’s project became more literal than originally intended

    On the Deptford foreshore, a ghoulish figure is sinking into the Thames. Performance artist zack mennell (who writes their name in lower case) wades to their belly button as a crowd watches on. As they dip down further, their mutant costume – sewn together from 24 adult nappies – swells with water … and waste.

    mennell’s work smears the personal and political across their body. The Thames performance is the finale of a project called (para)site, made in response to revelations of sewage discharge in our waterways and a reaction to the way benefit claimants are labelled as a drain on society. “OK,” mennell thought, “I’m going to be the parasite.” Their taking on of pollution was more literal than they intended; they contracted Weil’s disease from rat urine in the water.

  • Well-intentioned laws designed to safeguard nature frequently have the opposite effect

    The importance of protecting nature is not up for debate. One in six species in Britain is threatened with extinction. Since 1970, more than half our flowering plants have decreased in areas where they once thrived. In the 1950s, Britain’s hedgehog population was 30m strong. Now, it is believed to be under a million.

    All this demands action. The problem is that a lot of the action we’ve taken – mainly in the form of legislation – fails to target the biggest drivers of nature loss. Instead, it bites when we try to build: wind turbines, solar farms, railways or nuclear power plants, making their construction lengthier, more expensive or, in some cases, impossible.
