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.

  • 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 on to 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 where the peak temperature was above 32C. Half a century later and 32C no longer feels shocking.

  • Energy secretary expected to argue that UK clean economy is booming as private sector pledges over £100bn of investment

    Ed Miliband is to say that the UK must stick to net zero targets to deliver jobs and growth, as speculation surrounds the energy secretary’s role under a new prime minister.

    He will make the speech as data shows more than £100bn in green investment has been pledged by private sector companies in this parliament.

  • 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.

  • People trained to experience world as otters, salmon and other River Tone creatures for pioneering research

    What does a kestrel make of the dog sniffing in the long grass below? Why does an exhausted salmon pause before a weir? How will an otter experience the rumble of a passing train?

    Eighteen people have spent six weeks swimming, slithering and soaring as otters, salmon, earthworms, red deer and kestrels in an attempt to better document the risks for wild animals in our human-dominated landscape.

  • Prime minister was forced to row back on some policies despite strong support among voters for climate action

    Keir Starmer has faced a problem no Labour government has needed to deal with before. His energy and climate policies – core to solving the cost of living crisis – have come under attack from opposition parties, which have made dismantling the agenda one of their top priorities, second only to immigration, in their pitch to voters.

    This is new in British politics, where a cross-party consensus on the climate and environment has held at least since the days of Margaret Thatcher. She warned the UN of the climate crisis in 1988; David Cameron in 2006 urged voters to “vote blue, go green”; Theresa May enshrined in law the requirement to reach net zero greenhouse gas emissions by 2050; Boris Johnson championed the Cop26 UN climate summit in Glasgow in 2021; even Rishi Sunak only tried a partial rollback of green policies as a last desperate throw before calling an election.

  • 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.

  • Ten people affected in different ways by extreme weather are taking a case against the federal government to the UN

    As flood waters rose in Brisbane’s West End in February 2022, Brendon Donohue was trapped alone in his second-storey apartment for 10 days. The 33-year-old is legally blind and his movement is limited by Peters plus syndrome. He received evacuation alerts on his phone in the middle of the night. But with the lift, intercom and front entrance shut down he had no safe way out of the building.

    “It was terrifying,” he says. “The whole street was badly impacted with water. The power went out, which made me not able to contact anyone. I ran out of food but couldn’t get any into the building.”

  • A national heatwave plan has been activated to help people stay cool during the Netherlands’ increasingly hot summers

    Households in Amsterdam are being urged to hang their curtains outside their windows as health experts recommend simple hacks to moderate the heatwave rolling across the Netherlands, where homes were built for old-fashioned damp and coldish northern European weather.

    In a viral social media post last week, Eline Coolen, the heat coordinator at the city’s public health institute, urged sweaty city-dwellers to rig up temporary curtain rails or drape curtains or sheets outside to stop the sun’s rays reaching their large windows.
