Otrovi protiv štetočina nisu efikasni!

Baš kao što se problemi sa komarcima neće riješiti insekticidima, tako ni štetočine nikako nisu kontrolirane uporabom otrova.

Već dugi niz godina se otrov za štakore dostavlja u kućanstava diljem otoka u sasvim neadekvatnim vrećicama od celofana. Da stvar bude još gora, upute su unutra, tako da, ako ih želite pročitati, morate rukovati sa otrovom. Još nezgodnije je stranim vlasnicima kuća, koji ne znaju Hrvatski. Tako se može dogoditi i to, da je jedan stranac bijelu tabletu unutar pakiranja sa crvenim granulama smatrao protuotrovom. Srećom, nije bilo potrebe, da je upotrijebi, jer je tableta zapravo poseban otrov namijenjen za septičke jame, i naravno, ne sadrži nikakav protuotrov. Protuotrov za ove granule je vitamin K.

Upozorenja o isporučivanju otrova su rijetkost. Iako službene web stranice Starog Grada uvijek prenose obavijesti ovog tipa, u ostalim mjestima na otoku to nije slučaj. U Pitvama se obično, dan-dva prije zalijepi mala obavijest na kontejner.

Međutim, tijekom 2016. godine je došlo do poboljšanja situacije u Jelsi, gdje se upozorenja prenose kroz web stranicu Općinskog Vijeća, kao i kroz njihovu oglasnu ploču.

Po zakonu moraju vitamini biti pakirani na siguran način, ali čini se, da otrovi za štakore ne moraju. Ovaj neodgovoran i opasan običaj se nije promijenio niti ulaskom zemlje u Europsku Uniju. Vrećice se ostavljaju naizgled nasumice u mjestima po otoku. Događalo se, da sam ih pronalazila na različitim mjestima: kod prozora kuće, viseći iz mog poštanskog sandučića, čak i na svom autu! Način dostave je očito vrlo neodgovoran. Jesu li ali otrovi korišteni na odgovoran način? Najčešće se jednostavno postave u manjim količinama oko kuće, čak i tamo gdje mogu biti opasni za kućne ljubimce ili malu djecu. Najsigurniji način postavljanja takvih otrova - ako osjećate, da baš morate koristiti takve otrove - je upotrijebiti čvrstu cijev sa rupama za ulazak i izlazak, koje su dovoljno velike za miševe ili štakore, ali su premale za sve druge životinje.

Dok štetočine unutar zgrada sasvim sigurno predstavljaju problem i moguću opasnost za zdravlje, isto se ne može reći za miševe i štakore u divljini, koji imaju svoje mjesto (ako ništa drugo) u prirodnom prehrambenom lancu. Za bolji uvid u njihov način života, pogledajte video u nastavku, ili kliknite ovdje.

S obzirom na redovite doze otrova, štakori postaju otporni, stoga otrov nije rješenje. S druge strane, iako otrov ne bi trebao privlačiti druge životinje, ipak se to događa i nekoliko mačaka i pasa je već smrtno stradalo od otrova. Stvarno tužno i štetno, jer su mačke one, koje drže štakore i miševe, čak i zmije pod kontrolom. Za bilo koju veću pojavu štakora je najbolja metoda za izbjegavanje problema otpornosti na otrove pustiti upornog psa (kao što je Jack russelov terijer), da ih lovi ili koristiti zamke.

Lokalne vlasti moraju potrošiti značajan iznos na distribuciju tih otrova. Gledajući financijsko izvješće Općinskog Vijeća iz 2015. godine, nisam uspjela identificirati točan iznos potrošen na kampanju protiv štetočina i insekata, jer ove stavke nisu navedene pojedinačno. Troši li se taj novac na pametan način? Mislim da ne.

U Velikoj Britaniji su otrovi protiv štetočina dostupni, ali ne distribuiraju se na veliko kroz lokalne vlasti. Distribuirali su se (i možda se to još uvijek tako radi) samo na zahtjev. Prije nekih šezdeset godina, dok smo živjeli nedaleko Londona, moj brat, sestra i ja smo jednom po povratku iz škole pronašli neoznačenu staklenku na kuhinjskom stolu. Moja, po naravi neustrašiva sestra je navalila na staklenku i kako joj se okus činio "sirast", nastavila je jesti, da umanji svoju glad. Nismo imali pun frižider u onim danima, doduše nismo uopće imali frižider i ostava je bila prazna. Međutim, brat i ja smo bili oprezniji te smo odbili njezinu ljubaznu ponudu, da sa nama podjeli sadržaj staklenke. Možete zamisliti horor, koji je doživjela naša majka po povratku sa posla, kada je pitala za staklenku sa otrovom za štakore. Sestra je provela noć u bolnici, gdje su joj kroz pošteno ispumpavanje želuca spasili život. Mislim, da je to bilo zadnji put, da su iz općine ostavili neobilježen otrov za štakore u nečijem domu u nevino izgledajućoj, neosiguranoj staklenci.

Na Hvaru sam poslijednih godina uspjela zaustaviti isporuke otrova postavljanjem obavijesti na svojoj kući. Jednostavan natpis: "Otrov, ne hvala" preporučujem svima, koji ne žele biti opterećeni rukovanjem ili skladištenjem opasnih stvari.

Nekontrolirana distribucija otrova je očito opasna. Uz činjenicu, da otrov nije učinkovit postupak za suzbijanje štetočina, ovaj način postupanja je potrebno razmotriti i potrebno je trenutnu praksu znatno poboljšati - kao stvar od iznimne hitnosti.

  • Climate change committee finds move to renewable energy would also bring health, economic and security benefits

    Achieving the UK’s net zero target by 2050 will cost less than a single oil shock and bring health and economic benefits while insulating the country against future costs, the government’s climate advisers have forecast.

    Eliminating the UK’s reliance on fossil fuels by adopting renewable energy and green technologies, such as electric vehicles and heat pumps, would be the best and most cost-effective option for the future economy, the Climate Change Committee (CCC) found.

  • Analysis has found more than 3,000 mining operations within the most naturally precious areas of the planet, a much bigger footprint than previously thought

    Weda Bay is just one example of a global trend that could see the mining industry expand into some of Earth’s last areas of wilderness in search of minerals and materials to feed the global economy.

    Analysis produced for the Guardian by a group of academic researchers found more than 3,267 mining operations within key biodiversity areas (KBAs), accounting for nearly 5% of the mining sector’s global footprint. China, Brazil, Argentina and Mexico top the rankings for total surface mining area within key biodiversity areas, the most naturally precious areas of the planet.

  • Hemmed in by the sea and poor transport links, many young people from the Yorkshire town feel trapped, but there is also a pride in the area

    It’s the morning after a wet and stormy day in the Yorkshire seaside town of Scarborough. The waves, which the previous day had been crashing dramatically on the harbour walls, have calmed and a few brave souls have entered the water with surfboards. There is a man throwing a ball for his dog on the beach and a kayaker bobbing on the waves.

    Just up from the seafront in the centre of town, Jack and Charlie, both 17, are leaning forward listening to a story from 19-year-old Keane about his recent visit to a drama school in London, where he is hoping to apply for a place on an actor training course once he has saved enough money.

    Scarborough, on the North Yorkshire coast, was one of England’s first seaside resorts

  • Study shows animals hear very high frequencies, making it possible to design a deterrent to cut deaths

    Hedgehogs have been discovered to hear high-frequency ultrasound, raising hopes that they could be deterred from dangerous roads with ultrasound repellers.

    Vehicles are estimated to kill up to one in three hedgehogs, a big factor in the much-loved mammal’s drastic decline across Europe over recent decades.

  • They will soon be looking for nest sites to begin the huge effort of raising their brood of between eight and 10 chicks

    If there were an award for the most underrated British garden bird, the blue tit may well come out on top. Feisty and fascinating, this colourful little creature is so common and familiar that we often take it for granted.

    This could be because of the blue tit’s ubiquity. In both the main garden bird surveys in the UK – the RSPB’s annual Big Garden Birdwatch and the long-running BTO Garden BirdWatch – the species is always in the top five. With roughly 3 million breeding pairs, blue tits are as common in urban and suburban gardens as they are in rural ones.

  • Knightwood Inclosure, New Forest: I realise my knowledge of my favourite haunt is the size of the spidery-speck hanging in the heather

    In soft sunlight the woodland wakes. Brimstone butterflies boast their presence, a raven pair rattle overhead, and the first scents of warming earth drift upwards. Spring shouts its arrival across Knightwood Inclosure, home of the New Forest’s girthiest tree, the Knightwood Oak. It falls on deaf ears though; knelt in mud, immersed in undergrowth, I’m mesmerised in micro.

    In front of me, suspended on barely-there thread, hangs a speck of a spider. It was the disco-ball water droplets, clinging to its intricately woven web, that enticed me in. The spider is so small that my eyes and camera struggle to focus, flicking from a cream and tawny-coloured orb to a faded heather flower. When I do lock on, the abdominal markings gain clarity: inky black lines encasing two small spots.

  • More than 100,000 people have tuned in to watch ‘kākāpō cam’, which captures a rare flightless bird sleeping, tidying her nest and fighting off intruders

    On an island in New Zealand’s remote southern fjords, one of the world’s strangest and rarest parrots – the kākāpō – is caring for her tiny chick as fans from across the globe watch on.

    Through the black and white lens of a hidden camera, a fluffy orb with a kazoo-like squeak jostles for food from its mother’s beak. The mother, Rakiura, is attentive – scooping her chick under her large green wings, fending off an intruding bird, and periodically tidying her nest.

  • The Australian artist was a relentless self-promoter, prolific painter and pro wrestler. He loved a tall tale – but his true story was remarkable

    If you checked out the Archibald prize finalists back in 1983, one painting in particular might have caught your eye. Taking up seven feet of wall space, Dr Brown and Green Old Time Waltz is a psychedelic portrait of the then Greens leader, Bob Brown, rendered in rich colours and filled with hidden details: from faces smuggled into the trees to little green men walking around Brown’s feet.

    But just as noteworthy as the painting was the man standing next to it. Clad in hand-painted clothes, with painted false teeth in his mouth and a walking stick he didn’t really need in his hand, stood Harold “the Kangaroo” Thornton, the artist and self-described “greatest genius that ever lived”.

  • Recent attack on plants led to fears of escalating strikes, but Iran knows drought has left it equally vulnerable

    In 1983, the CIA determined that the most crucial commodity in the Gulf was its desalinated potable water.

    Although the loss of a single plant could be handled, “successful attacks on several plants in the most dependent countries could generate a national crisis that could lead to panic flights from the country and civil unrest”. And the greatest threat to the region’s water supply? “Iran.”

  • Reaching up to 100ft, these massive piles contain tonnes of salt that keep roads clear – but pose environmental risks

    Most mountains take tens of millions of years to form. Toronto’s newest mountain took just days.

    Towering atop the crowns of evergreens, it has no skeleton of limestone or granite. There are no spires, cornices or headwalls. It is simply piles upon piles of snow, mixed with a toxic cocktail of road salt, antifreeze, oil, coffee cups and lost keys. It is the final resting place for the forces of nature that have battered the city in recent weeks – and a daunting environmental hazard.
