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.

  • António Guterres urges world to act on fossil fuels as continent braces for record-breaking heat; French PM to hold emergency meeting after heat deaths

    Italy’s health ministry has declared a red heatwave alert in 15 cities including Milan and Rome on Tuesday and said the number would go up to 16 on Wednesday.

    During a red alert – the highest level – the ministry advises people to eat light, stay indoors in the hottest parts of the day and sprinkle themselves with cool water.

  • Half a century on, Britain braces for temperatures up to 40C as global heating brings yet more extreme weather

    The summer of 1976 is seared into national memory as one of record heat. Harvests failed, farmers despaired, Britain imported an extra million tonnes of grain, food prices rose by 12%, taps ran dry, and each day, 250 people died from heat-related deaths.

    The heatwave, which began 50 years ago on Tuesday, brought 15 consecutive days on which the peak temperature was above 32C. Half a century later and 32C no longer feels shocking.

  • Researchers say it is ‘quite wild’ to see fires at such high northern latitudes happen so early in the year

    Scientists have expressed concern after two wildfires broke out within a week of each other on the Arctic island of Greenland earlier this month.

    Fires were burning close to Sisimiut, Greenland’s second largest town and a popular tourism centre, on 14 and 15 June, satellite imagery has shown, while a second blaze hit Kujalleq, on the island’s southern tip, on 17 June.

  • The cost of the traditional takeaway has doubled since 2019, and more outlets are trying to tempt customers with cheaper options such as coley, pollack and hake

    In late April, visitors to Harbour Lights in Falmouth, Cornwall, may have raised an eyebrow. The fish and chip shop was in the midst of a “cod-free week”, its owners having removed cod from its menu entirely.

    It was the second time owner Pete Fraser had undertaken the experiment, 15 years after the first. He also removed cod from his shops in Penzance and Helston, replacing it with coley, pollack, hake and hoki. The result was very different. “Some of the feedback we had, which certainly wasn’t what we got when we ran it years ago, is ‘Can you repeat this?’ Before, it was like, ‘Have you guys lost your head’?”

  • Energy secretary hails £100bn milestone in this parliament and says it is ‘only the start of what we want to achieve’

    Ed Miliband has hailed a boost to UK jobs and growth as government data reveals that private sector companies have pledged more than £100bn in investment into the green economy so far in this parliament.

    Offshore wind, solar power and the electricity grid make up the bulk of the planned investment, most of it between 2024 and 2031, which will go to all regions of the UK and comes from a mixture of UK companies and overseas sources including the EU and Japan.

  • The country’s biggest tree – named Heaven Sword of the Da’an River – is a carbon-storing behemoth hosting whole neighbourhoods of wildlife. But this and other giant trees are under threat

    The higher you climb up the gigantic, millennia-old trees of Taiwan’s forests, the more layers of habitat and life emerge. On the forest floor, ferns thrive in the moist shade. Flying squirrels and owls sleep inside the hollow tree trunks. Yellow bell-shaped rhododendron flowers spring from the lower tree canopy. Higher still, dense lichen spread. Up in cloud-drenched branches, a rare, hardy orchid, Bulbophyllum ciliisepalum, can be spotted.

    “In one tree, every species has their preferred location,” says Dr Rebecca Hsu, assistant researcher at the Taiwan Forestry Research Institute. “Every metre the temperature, the wind, the sun, the light is different.”

  • Queen’s University, Belfast:The corvids in the branches above me spring a surprise – there’s a black crow among them

    The rain hurries me to shelter at the woods’ edge, but I’m scarcely under the branches of a mature sycamore when the canopy starts to thrash. Abrasive voices erupt from the foliage as a rabble of crows dispute. One leaps into a gap between the leaves, crouching, its ash-grey body low over a branch and fanning its black tail. The throat inflates to bray the bird’s anger. In response, the object of its fury hops on to the branch above it, all the while giving as good as it gets. Something niggles me about that one – I squint, then blink in surprise. It’s a black crow.

    As a bookish youngster growing up in rural County Fermanagh, it took a while for me to grasp that the crows I encountered in real life were not, in fact, black. The hooded or grey crow is the common crow across all of Ireland. With its two-tone livery of grey torso and black extremities, it’s a handsome bird. The “hoodie” is also found in the north of Scotland. The closely related all-black carrion crow is a far more familiar sight throughout the rest of Britain, with sparse numbers along the east coast of Northern Ireland.

  • In HBO documentary The Welcome Table, director Josh Fox brings together people from across the world whose lives have been dramatically altered by the climate crisis

    In an age of division, director Josh Fox is hoping to bring people of all kinds together. Specifically, he wants them to share a table – to break bread for a meal, and come together in exuberant song.

    In his new documentary film The Welcome Table, the director of the the Emmy-winning Gasland travels around the world to talk to people at the leading edge of global warming’s effects. The film is part stark warning of the climate crisis, part opportunity to enter into the experience of those living in the corners of the globe. It culminates with the sounds of these individuals together at an enormous table in New Orleans, eating and rejoicing.

  • The colour-coordinated ‘clean girl’ athleisure aesthetic is dead. Now it’s all about mismatched outfits and vintage sportswear

    At first, the goblins came for our downtime. Going “goblin mode” was a lifestyle confined to the home – to the bed, mostly. The “comforts of depravity” it brought (“watching 90 Day Fiancé on mute while scrolling endlessly through social media, pouring the end of a bag of chips in your mouth”, for example) weren’t compatible with doing anything productive.

    Enter the gym goblin. The optics remain much the same – think ancient T-shirts, knackered socks, oversized cardigans – but the setting has changed, with goblincore devotees rising up from unmade beds, Diet Cokes in hand, to hit the treadmill. It’s Diana, Princess of Wales’s oversized college sweatshirts meets Josh O’Connor’s half-tracksuit look for the Disclosure Day press tour – and the polar opposite of the matcha-drinking, Lululemoned “clean girl” aesthetic that dominates fitness circles.

  • Is it an alien? A dinosaur? Is it going to kill us all? Our writer hits Ashdown Forest for the Big One Hundred celebrations – and finds its magic enchanting new generations

    The rolling idyll of heath and forest, spinney and stream that gave us the Heffalump, the Woozle and, most famously of all, Winnie-the-Pooh, has a new fantastical resident. Creeping through the bracken, making strange cooing and purring noises, is a shapeshifting creature with a huge tubular nose and eyes inspired by adders. It shimmies with iridescent patches and the psychedelic purple of flowering heather in high summer.

    Poppet, a puppet made by costume designer Jack Irving and brought to life by a team of 10 award-winning puppeteers, is performing for schoolchildren in Ashdown Forest, East Sussex. The primary school class squeal with delighted fear as the purple apparition transforms itself from caterpillar to bird to munching monster in sinuous moves.
