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.

  • Monday predicted to be hottest May day on record by large margin, as UK braces for ‘super El Niño’ summer

    Temperatures are expected to hit 35C in parts of England on Monday, in an “unprecedented” May heatwave.

    The Met Office is already predicting that records will be broken. A spokesperson said: “Today will be the hottest day in May in the UK in our temperature records, with highs of 35C expected. The current May record is 32.8C. Records are usually only broken by tenths of a degree, making this heatwave unprecedented for the time of year.”

  • Rain overwhelms sewer system in parts of US city, while temperatures in France break May record

    New York City saw flash flooding on Wednesday, as large parts of Brooklyn and Queens received about 2in (50mm) of rainfall in as little as 20 minutes. Officials said the deluge caused water to flow into the sewer system at a rate of up to 6in an hour, quickly overwhelming an aged network that was designed to accommodate just 1.75in an hour.

    Residents and commuters found themselves wading knee-deep through flood water that flowed with dangerous speed in places. One video showed a woman alighting from a bus losing her footing and being dragged along by the torrent of water. Several major roads were blocked, including the Long Island Expressway, and subway services were disrupted as water spilled into stations. Large amounts of mud and other debris was left behind; videos showed bags of rubbish being swept down streets along with loose litter.

  • Most people have joyful memories of playing outside as children – and now wildlife charities are urging people to ‘rewild their inner child’

    Climbing trees, squelching in mud, paddling in ponds or making dens in the woods – people’s memories of playing outside as children are often vivid and, a new poll has found, overwhelmingly positive, even those who remember falling in cowpats.

    Almost 90% of UK adults had rosy memories of the excitement and the feeling of freedom that outdoor play had brought them, the survey found. However, almost half of adults now spend less than three hours a week in natural settings such as gardens, parks, fields or woods, according to the survey. For one in 10 it is less than one hour.

  • Charter to be adopted along river’s entire catchment from Cambrian mountains to Chepstow and Bristol Channel

    The entire catchment of the River Wye has been formally recognised as a living ecosystem with intrinsic rights in a charter, a UK first that campaigners hope will help save the highly polluted river.

    The charter was celebrated at a community event at the Hay-on-Wye literary festival on Sunday. It includes the right to flow, to biodiversity, to be free from pollution, to be supported by a healthy catchment, to regenerate, and the right to be represented, described as a “significant step” towards protecting and restoring one of the UK’s most beloved rivers.

  • Definition of green facilities made in 2022, before release of ChatGPT, says Action to Protect Rural Scotland

    A Scottish government policy designed to encourage datacentres to build in Scotland could lead to a massive volume of carbon emissions being ignored, according to an analysis by a Scottish charity.

    “Green datacentres” are at the heart of Scotland’s ambitions to develop economically. Enshrined in national policy, they are part of a larger, UK-wide effort to attract big AI investment to Scotland.

  • Talybont, Ceredigion: On a crisp, post-rain morning, I take a walk among bright hawthorn blossom and the glittering pools of Cors Fochno

    On the edge of Talybont, the small cemetery, kempt and cared for, overlooks the coast and the wild brown swathe of Cors Fochno (Borth Bog). A burial ground is perhaps an odd place to begin a walk, but, as a friend remarked, it’s infinitely better than ending one there.

    The early rain has cleared so the air is crisp and the colours deep. In the foreground, grassland fields slope away towards the wild expanse of the bog, bounded by wooded hedgerows bright with hawthorn blossom. The first cut of silage has been secured, baled and removed, and a few cattle are grazing the aftermath with interest while red kites traverse overhead. The surface of the bog, marked here and there by glittering open pools, shimmers slightly in the heat of the day. Across the Afon Dyfi, the steep-faced sand dunes of Aberdyfi are visible before the eye is drawn further off to the line of hills that defines the Llŷn peninsula.

  • Temperature reaches 30.5C in Kent as amber health alerts issued before bank holiday temperatures rise

    The UK has recorded its hottest day of the year so far, with temperatures reaching 30.5C in Kent as forecasters warned more extreme heat could follow over the bank holiday weekend.

    The temperature in Frittenden also marked the first time since 2012 the UK has reached 30C in May, according to the Met Office.

  • Technological interventions face huge financial or practical challenges, but there is another way

    In 2019, my scientific research was nearly brought to an early end when my team and I published the bombastic statement that natural forest restoration was the “best climate change solution” available in a paper for the peer-reviewed journal Science.

    I remember a colleague from the World Wildlife Fund advising me that this message represented career suicide. He argued that people would be furious because reducing greenhouse gas emissions was the most urgent priority. The revival of nature might help with 30% of our carbon drawdown needs, but you cannot stop rising temperatures without cutting emissions.

  • The Martuwarra Fitzroy catchment is home to four of the world’s five sawfish species, which rely on large groundwater-fed pools to survive the dry season

    Conservationists fear a government plan to double groundwater extraction from the Martuwarra Fitzroy River catchment in Western Australia could jeopardise threatened sawfish populations.

    The untamed river, which flows 700km through the Kimberley to King Sound, is considered the last stronghold for sawfish globally and is home to four of the world’s five species.

  • Firefighters are racing to douse flames on California’s Santa Rosa Island as experts express concern for unique habitat

    On the south-eastern corner of Santa Rosa Island lies a grove of a few thousand Torrey pine trees, some of them more than 250 years old. The only other place on earth where these gnarled pines exist is in San Diego county, but biologists classify the two groves as different subspecies. So when a rare wildfire broke out on Santa Rosa Island late last week, firefighters raced to keep it from spreading into the grove, where it threatened to consign the island’s Torrey pines to extinction.

    So far, they appear to be succeeding – even as the 18,000-acre fire has torched nearly one-third of the island’s surface. But biologists who have studied Santa Rosa Island’s unique ecology are watching anxiously as the fire continues to burn a part of the island that is home to six plants found nowhere else on the planet.
