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 among 10 countries to build 100GW grid in North Sea linking countries through subsea cables

    The German chancellor, Friedrich Merz, has said he wants the North Sea to become the “largest reservoir of clean energy worldwide”, as he announced plans to accelerate efforts to link up offshore wind power projects with Europe.

    The UK and nine other European countries have agreed to accelerate the rollout of offshore windfarms in the 2030s and build a power grid in the North Sea, in a landmark pact to turn the ageing oil basin into a “clean energy reservoir”.

  • Caistor St Edmund, Norfolk: As chief clothes-washer in our home, I see egrets and snowdrops and wonder how anything living in the marsh or riverbank can stay so clean

    The dazzling white of snow gave way to sludge underfoot. Then came the heavy rain, returning us to mud and the drabness of late winter.

    A ghost rises beside the lake, taking form as it separates itself from the low mist. Against the grey of the sky, the impossible brilliance of its perfect white, metre-wide wingspan is jolting. It’s a little egret, a small, white heron with impressive wings.

  • An extraordinary mosaic of wildlife has made Britain’s urban jungle its home

    London is the only place in the UK where you can find scorpions, snakes, turtles, seals, peacocks, falcons all in one city – and not London zoo. Step outside and you will encounter a patchwork of writhing, buzzing, bubbling urban microclimates.

    Sam Davenport, the director of nature recovery at the London Wildlife Trust, emphasises the sheer variation in habitats that you find in UK cities, which creates an amazing “mosaic” of wildlife.

  • Researchers found a new way to filter and destroy Pfas chemicals at 100 times the rate of current systems

    New filtration technology developed by Rice University may absorb some Pfas “forever chemicals” at 100 times the rate previously possible, which could dramatically improve pollution control and speed remediations.

    Researchers also say they have also found a way to destroy Pfas, though both technologies face a steep challenge in being deployed on an industrial scale.

  • Pollution from wood burners kills thousands but proposed emissions limit would cut toxic particles by 10%

    New wood-burning stoves will carry a health warning highlighting the impact of the air pollution they produce, under UK government plans.

    Ministers have also proposed cutting the limit on the smoke emitted from wood burners by 80%. However, the measure would only apply to new stoves, most of which already meet the stricter limit. The new limit would cut the annual toxic emissions from wood burning in the UK by only 10% over the next decade, according to the consultation.

  • Therapy lights, sunrise alarm clocks and infrared saunas can all help shake the winter blues as the weather drops

    As a lifelong Canadian, I’m no stranger to that familiar sinking feeling in my chest as the days get shorter, dimmer and colder. I suffer from seasonal affective disorder (Sad), which also affects about one in 20 people in the US.

    “Sad is a type of depression that happens at certain times of the year, usually in the fall and winter when there’s less sunlight,” said Dr Stefanie Mazer, a licensed psychologist and founder of the psychology practice Mindwise, Inc. Changes in sunlight can affect your body’s internal clock and levels of serotonin and melatonin, which influence mood and sleep, Mazer explained. People with Sad often feel low energy, sadness and irritability, with noticeable changes in sleeping or eating.

  • The most popular posts on r/animalid are exotic lizards and rare birds – but it’s the haziest trail cam screenshots that feel the most dangerous, the most spectacular

    I spent the first decade of my life in Vancouver Island, Canada, in an area rich with parks, lakes and forests. Deer would occasionally wander into our neighbourhood and nibble on the blossoms in our front yard. In that neck of the (literal) woods, mountains and deer also mean cougars.

    My sister and I would play at a local park, then walk home along a track parallel to a dense forest. My older sister, being three and a half years ahead of me in life and therefore lightyears ahead of me in wisdom, would helpfully declare that if we encountered a cougar it would attack me, not her, as I’m the smaller prey.

  • Electric van sales are behind government targets, but those fleets that have switched are seeing a real difference

    Swinging a fully laden electric van around a training centre in Bishop’s Stortford feels easy, with instant acceleration that belies the racks of heavy equipment in the back. Perhaps too easy, as the sudden shriek of its proximity sensor suggests the Guardian was a whisker away from a bill for some new paintwork.

    The van in question belongs to Openreach, BT’s fibre broadband subsidiary. It is one of 6,000 electric vans out of 23,400 in Britain’s second-largest commercial fleet – and a further 1,000 are expected to be added by March.
