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.

  • Every autumn, Corvo Island in the Azores turns off its public lighting for a few key days to help fledgling Cory’s shearwaters as they attempt to fly to the ocean guided by the stars

    Once a year, Corvo, the smallest and most northerly island of Portugal’s Azores archipelago, goes dark. Since 2019, the island’s 450 or so inhabitants have chosen to switch off the lights every autumn for five nights to tackle the disastrous effects of artificial light on Cory’s shearwaters, a seabird endemic to the Atlantic Ocean.

    It began in 1991 when the community noticed huge numbers of deaths among young shearwaters.

  • The 2030 target for 80% of new cars to have zero emissions could be cut to as low as half

    Electric cars make people happy. More than nine in 10 EV drivers – 94% in a recent poll – are saving money, and a similar number would stick with electric for their next purchase, and recommend them to family and friends. Sales are soaring: more than half of the new cars sold in the UK last month were electric, if hybrids are taken into account, and about 28% of new car sales overall were electric only.

    This is hardly surprising, given that soaring petrol and diesel costs have pushed up the price of a full tank to about £120. EV drivers are paying about 2.4p a mile.

  • Tim and Geli Harris have spent more than a decade fighting to protect Catfield Fen, a rare wetland in the Norfolk Broads

    Polluters and regulators who fail to stop pollution must quake in their boots when they receive a letter from the lawyers for Tim and Geli Harris. The couple, who farm 460 acres in the Norfolk Broads, have now scored a hat-trick of landmark legal victories to save an internationally important wetland after they won again in the high court this month.

    Lady Justice Lieven found that Natural England failed in its statutory duty to protect Catfield Fen from pollution after nitrates and phosphates washed from arable fields into one of the finest examples of calcareous fen in western Europe, home to 2,500 species including rarities such as the fen orchid, crested buckler fern, breeding bittern and swallowtail butterflies.

  • Season will be less vibrant with trees such as birches, which usually offer a striking burst of yellow leaves, already bare

    Among a canvas of copper, red and purple autumn leaves on display at Wisley garden in Surrey, south-east England, one tree stands conspicuously naked.

    “The birch has lost all its leaves,” says Guy Barter, the chief horticulturist at the Royal Horticultural Society. “That’s the effect of drought, so it’ll have no autumn colour this year.”

  • Exclusive: Angela Eagle tells utility bosses next price review ‘must focus on value for money for customers’

    Ministers will make an unprecedented intervention in water bills and how companies prioritise investment, directing bosses to bring down costs and stop leaks and sewage overflows.

    Angela Eagle, the environment secretary, has told suppliers in England and Wales she plans to intervene in the next price review – conducted by the water regulator, Ofwat.

  • Brownsea Island, Dorset: I’ve been here lots of times to see the squirrels, so I know exactly where to find them – behind the church in the woods

    Every October my family have an annual trip to Brownsea Island. We go in autumn because this is a good time to see the red squirrels. In the other seasons, they are high up, hidden in the trees. We catch the ferry from Poole Harbour, and we know we are close when we can see the castle come into view. When we arrive we’re greeted by nosy chickens and attention-seeking peacocks on the lawns.

    We go behind the little church into the woods. It is a different world there. There is a mix of crunchy and soggy brown leaves on the ground and little mushrooms popping up from the earth. Some mushrooms are sprouting from rotting logs.

  • Concrete sprawl in Yaoundé has devastated the city’s trees and parks, so volunteers are stepping up, shrub by shrub

    A little piece of paradise is buried under the asphalt that is now lined with parked cars. The romantic spot where Sosthène Hugues Ngono used to bring his first dates had been green and beautiful. “It wasn’t just a park,” he says, standing at the edge of what is now a private car park in Cameroon’s capital, Yaoundé.

    “It was where I came to clear my head when things felt confused,” he says. “Where I met people; where I fell in love, more than once.”

  • Queensland researchers say a published study contains ‘silly mistake’ that over-inflates vaccine’s efficacy but the regulator is standing by decision to approve it

    At wildlife hospitals across eastern Australia, many koalas brought in have distinctive brown patches on their bottoms – a sign of urinary incontinence and a painful inflamed bladder. Others have red, weeping eyes, pointing to a bacterial disease that can cause blindness in the endangered marsupials.

    Chlamydia infection, also known as chlamydiosis, is the most significant disease affecting the animals. The culprit is most commonly the bacterium Chlamydia pecorum, which is spread via mating or close contact.

  • Dom Phillips warned that Jair Bolsonaro would make life more dangerous for reporters and the Amazon rainforest, and that his sons were even more extreme

    “Bolso shows all signs of fascism, as do his supporters,” the murdered British journalist Dom Phillips told me before his death. “His sons are all more extreme if anything.”

    These words were written in 2018 by the Guardian contributor shortly before the election of the far-right former army captain Jair Bolsonaro as president of Brazil – a prospect that Dom viewed with dread.
