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.

  • Exclusive: Ministers accused of trying to keep investment firm’s withdrawal from partnership with NatureScot under wraps

    A funding deal to raise £100m from private investors for urgently needed nature restoration in Scotland has fallen through without the Scottish parliament being told.

    The Guardian has learned that Aberdeen, the investment firm, decided to withdraw from a partnership with the agency NatureScot to raise at least £100m for conservation projects from commercial and private investors late last year.

  • The government hails the ‘green revolution’ as a solution to economic decline, but some young jobseekers say the rhetoric does not match their experience

    On paper, Jake Snell, 19, sounds like the perfect candidate for a role in the UK’s burgeoning green energy sector. He has high grades in maths and physics A-level, a distinction in BTec engineering and another distinction in an extended engineering diploma. He has also done work experience at an engineering company.

    He is from Lowestoft, a coastal town in Suffolk, outside Great Yarmouth. Both towns contain areas that fall within the most deprived 20% in England and are part of a wider pattern of coastal places with low employment opportunities.

  • We delve into the best stories on how sport is changing around the climate crisis, and what can be done to navigate a way forward

    Nelson Mandela said: “Sport can create hope where once there was only despair.” Too optimistic? In 2026, almost certainly. Sport is still a common language, uniting unlikely groups like an all-powerful Esperanto, but it is in trouble.

    The pitches we play on, rivers we swim, seas we surf, mountains we climb, parks we run in, air we breathe – all are being degraded by the burning of fossil fuels as the climate crisis turns the sporting landscape upside down.

  • Amid growing evidence of fungi’s key role in ecosystems and storing carbon, African scientists are championing the need to preserve ‘funga’ as much as flora and fauna

    Madagascar has long been celebrated for its remarkable wildlife, with the vast majority of its species – from ring-tailed lemurs to certain species of baobab trees – found nowhere else on the planet. But when discussing the island nation’s endemic treasures, fungi are often left out of the conversation.

    Yet “fungi are some of the most important things in the world”, says Anna Ralaiveloarisoa, a Malagasy scientist. “They feed 90% of terrestrial plants. Without them, there is no life on the Earth.”

  • Rising temperatures and extreme drought are driving more destructive spring fires across the Great Plains. This year, forces aligned to create the perfect storm in Nebraska

    In a normal year, the vast grasslands that roll across the American Great Plains would be starting to green. But at the center of the US, where most of the nation’s beef producers graze their herds, this spring brought fire instead of moisture, leaving more than a million acres black and barren.

    Multiple blazes raged across Nebraska, where the records for the annual acreage burned were obliterated in a single month. The state logged the largest blaze ever recorded when the Morrill fire cascaded across more than 642,000 acres (260,000 hectares) before it was contained in March.

  • A skull fragment found in a tray of unsorted fossils collected more than a century ago leads to discovery

    A prehistoric fossil, hiding in plain sight in museum storage for more than a century, has revealed that giant echidnas once roamed Victoria.

    The Owen’s giant echidna, Megalibgwilia owenii, lived during the Pleistocene, a geological epoch that began 2.5m years ago. It grew to about 1 metre long and weighed up to 15kg – about twice the size of Australia’s modern echidnas.

  • Dozens of feral pachyderms linked to drug kingpin to be killed because of threat to native species and villagers

    Colombian officials have authorized a plan to cull dozens of hippos descended from animals brought to the country in the 1980s by Pablo Escobar, after the feral beasts displaced native species and threatened local villagers.

    The environment minister, Irene Vélez, said the decision was reached because other methods to control their population had been expensive and unsuccessful, including neutering some of the animals or moving them to zoos. Vélez said that up to 80 hippos would be affected by the measure. She did not say when the hunting would begin.

  • Trump’s EPA chief Lee Zeldin’s presence shows how much influence climate deniers now have, experts say

    As scientists confirmed that March was the United States’ most abnormally hot month in recorded history, dozens of climate deniers gathered to promote misinformation and tout their newfound influence on federal policy.

    At a conference hosted by the prominent science-denying thinktank the Heartland Institute last week, a crowd of mostly middle-aged men in suits claimed the world is finally waking up to the idea that the climate crisis does not exist.

  • Male humpback, which has repeatedly stranded and freed itself in Germany in past month, is to be left in peace to die

    When a 10-metre long humpback whale became stranded on a sandbar in the Baltic Sea last month, none of those who went to its rescue could have known how it might turn lives and livelihoods upside down.

    About a month after the first sighting of the male whale, near Wismar and Timmendorfer Strand on the north German coast, it has repeatedly stranded and freed itselfand is now stranded once more, with rescuers saying it is in the throes of death.
