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.

  • Christmas Day expected to be dry and bright, with low temperature warnings posing greater risk to vulnerable people

    Christmas Day will bring bright weather in much of the UK, but a cold health alert has been issued warning of a “greater risk to life of vulnerable people”.

    While the prospect of a white Christmas is “highly unlikely”, according to forecasters, the UK Health Security Agency (UKHSA) has issued a yellow cold health alert from 6pm on Christmas Day to noon on 27 December for south-west England.

  • Seaweed has become a key cash crop as climate change and industrial trawling test the resilient culture of the semi-nomadic Vezo people

    Along Madagascar’s south-west coast, the Vezo people, who have fished the Mozambique Channel for countless generations, are defined by a way of life sustained by the sea. Yet climate change and industrial exploitation are pushing this ocean-based culture to its limits.

    Coastal villages around Toliara, a city in southern Madagascar, host tens of thousands of the semi-nomadic Vezopeople, who make a living from small-scale fishing on the ocean. For centuries, they have launched pirogues, small boats carved from single tree trunks, every day into the turquoise shallows to catch tuna, barracuda and grouper.

    A boat near lines of seaweed, which has become a main source of income for Ambatomilo village as warmer seas, bleached reefs and erratic weather accelerate the decline of local fish populations

  • Scientists working for government breed biological control agents in lab to take on species choking native wildlife

    Crayfish, weevils and fungi are being released into the environment in order to tackle invasive species across Britain.

    Scientists working for the government have been breeding species in labs to set them loose into the wild to take on Japanese knotweed, signal crayfish and Himalayan balsam, and other species that choke out native plants and wildlife.

  • Dursley, Gloucestershire: We have to embrace these darker months and get outside, but there’s also only so much wind and sludge I can take

    Winter is tiring. The footpath is a gully of slop, and each step forwards is a little slip backwards. The north-facing slope was OK – the frost hadn’t been thawed by the sun, and crunchy ground is better than slippy ground. But the rest of Gloucestershire has turned into slurry.

    It’s just as well that I enjoy it; I do this every week. For the last seven years I’ve been going out on a Friday, taking some combination of buses and trains to wherever the previous walk ended, and continuing. My Friday walk is a single tangly line stretching from Birmingham to Dorset, and the Malverns to the M25, and I go whatever the weather.

  • Met Office says temperatures are tracking ahead of 2022 after year of heatwaves and drought, though late cold spell could yet intervene

    Forecasters say 2025 is “more likely than not” to break the record for the hottest year in the UK since records began, after a summer of heatwaves and drought followed by a mild autumn.

    According to the Met Office, the official forecaster, the mean temperature for 2025 is tracking well ahead of the previous highest year, set in 2022. However, a colder spell expected from Christmas until the new year makes it too close to call definitively.

  • From Copenhagen’s cycle lanes and Vienna’s shared parks to Barcelona and London’s unfulfilled potential, better living is close at hand

    The angry rumble of a speeding SUV. The metallic smog of backlogged traffic. The aching heat of sun-dried neighbourhoods baking in an oven of concrete and asphalt.

    For most people, the mundane threats that plague our environments are likely to annoy more than they spark dread. But for scientists who know just how dangerous our surroundings can be, the burden of knowledge weighs heavy each day. Across Europe, environmental risks cause 18% of deaths from cardiovascular disease and 10% of deaths from cancer. Traffic crashes in the EU kill five times more people than murders.

  • U-turn lifts limit from £1m to £2.5m after protests and warnings that family farms were at risk

    Ministers will increase the threshold for taxing inherited farmland from £1m to £2.5m after months of pressure from campaigners and MPs representing rural areas.

    In a statement slipped out just before Christmas, the environment department announced the U-turn, which will apply from April when the tax kicks in.

  • Thousands of farms set to go bankrupt as grain farmers in particular hit by trade disruptions caused by price hikes

    Donald Trump, having promised to “NEVER LET OUR FARMERS DOWN”, appeared to come through for them this month when he unveiled a $12bn aid package. Industry leaders say thousands of farms will still go bust this year.

    While the US president has vowed to increase domestic farm production, and even claimed this formed a “big part” of his plan to lower grocery prices for Americans, many US farmers are grappling with mounting financial issues – compounded by Trump’s agenda.

  • Studies show crustaceans can learn, remember, solve problems and form relationships

    Crustaceans are a festive season staple for many families, particularly in Australia where an estimated 18.5m kilograms of prawns and more than 150,000 lobsters are eaten over Christmas and new year.

    Globally, trillions are caught and consumed each year. Australia is a major producer, with prawn, lobster and crab industries valued at more than $1bn.
