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.

  • Government keen to avoid panic as oil price surges, but perhaps households need advice on reducing consumption

    Labour ministers sent out in recent days to respond to the looming energy crisis sparked by the Iran war have essentially stuck to that reassuring wartime slogan: keep calm and carry on.

    “I think people should go about their lives as normal, knowing that the government is taking action to bring energy bills down,” James Murray, the chief secretary to the Treasury, told BBC Radio 4’s Today programme on Tuesday.

  • Merlin could disappear in worst-case scenario, with British isles facing ecological ‘point of no return’

    The merlin, Britain’s smallest bird of prey, is one of more than 200 species that will become extinct in the UK if action is not taken to curb emissions and unsustainable land use, a study has claimed.

    According to the UK Centre for Ecology & Hydrology (UKCEH), there is a 20-year window in which decisions on climate and land use will determine the fate of dozens of Britain’s native species.

  • Research from the University of Exeter find that the method could help reduce thefts by as much as 50%

    Gulls thrive on snatching chips from unwary beachgoers, but now research shows that painting a pair of eyes on takeaway boxes could put gulls off, reducing thefts by as much as 50%.

    Laura Kelley, from the University of Exeter, and colleagues presented herring gulls with tempting takeaways at a number of seaside towns in Devon and Cornwall. When faced with a choice between a box with eyes painted on it and a plain box, the gulls were slower to approach the box with eyes and less likely to peck at it. And the findings, which are published in Ecology and Evolution, show that the effect is sustained, with gulls remaining wary of the boxes with eyes on them, even after repeated exposure.

  • Stoke-on-Trent, Staffordshire: These early spring bloomers are a favourite of mine, a model of nature’s generosity, yet so often ignored

    The drier days of March are always marked by the hum of dutiful grass-cutting on our urban Midlands housing estate, and so I know I will have to look to the gutters and pavements to spot my favourite spring flower. Sure enough, the first one I see is blooming in a crack beside a crumbling wall on the busy main road. I can’t help but let out a joyful shout, leaning down to cradle its fierce lion head in my fingers. Hello, dandelion, how I’ve missed you!

    Perhaps it’s being a wheelchair user, closer to the ground than most, that has given me a special place in my heart for them, or perhaps it’s because I’ve always felt like a weed myself, inconvenient and growing in the wrong place. Either way, I have long been kindred spirits with keen-eyed toddlers who love to carry them in their fists. I’ve often joked that my bridal bouquet will be dandelions, please. I can honestly think of no finer flower. Why? Because there is no better example of nature’s generosity than a dandelion.

  • Government told to focus on transition to mix of wind, solar, tidal and nuclear energy

    More drilling in the North Sea would do nothing to improve the UK’s energy security, former military leaders have said, as a new analysis finds no fossil fuel importer is safe from chokepoints in the global supply chain.

    The government should focus on a rapid transition to a mix of wind, solar, tidal and nuclear energy to ensure the UK’s future security, the former military leaders told the Guardian, as well as a programme of energy efficiency and a “major renewal” of the electricity grid.

  • ‘Precious ocean life is being pushed to the brink,’ say campaigners, arguing that overfished marine areas are ‘protected only on paper’

    Almost 40% of England’s seas are designated as marine protected areas. Their purpose, the government says, is “to protect and recover rare threatened and important marine ecosystems … from damage caused by human activities”.

    And yet in the four years to 2024, trawlers using vast nets, including those that scour the seabed, caught more than 1.3m tonnes of fish within them, according to official figures that campaigners say show they are “little more than lines on a map”.

  • Brittlestars, sea anemones and a catshark among new-to-science species collected during expedition off the Queensland coast

    Marine scientists have discovered more than 110 new fish and invertebrate species in the Coral Sea – a figure they believe could exceed 200 as more are identified.

    The species were found in waters between 200 metres and 3km deep in the Coral Sea marine park, Australia’s largest marine protected area, which spans nearly 1m sq km to the east of the Great Barrier Reef.

  • Home to one of the world’s largest deposits of freshwater, the Great Lakes region will soon host next-generation generators – just as prices are being hiked across the US

    Submersible hydroelectric technology deployed across the Great Lakes could become a key cog in clean energy efforts, supporters say, amid surging electricity demand and costs.

    Home to one of the largest deposits of freshwater on the planet, the Great Lakes region has on its shores some of the largest cities in North America in Chicago, Toronto, Montreal and Detroit, where electricity demand is growing. While none of the five Great Lakes have significant tides or currents to fuel hydropower, several of the waterways that link the lakes do.

  • The great naturalist, who is about to turn 100, is still surprised by wildlife in his new series about British gardens. But not every pet owner will be happy with his top tips

    Whenever David Attenborough speaks, the world listens – so his latest BBC programme, which heralds the broadcaster’s 100th birthday, is bound to attract attention.

    Secret Garden, which features five different UK gardens, might not be what people normally expect from Attenborough, says the show’s series producer, Bill Markham, as “there’s no lions and tigers”.

  • For decades, there was no record of Andrena rehni exisiting in the US. In 2018 it was found in Maryland and five years later I found it in New York State

    I’ve loved insects ever since I was a kid and spent summers looking for them. My mum would always tell me that from the age of one – even before I could walk – I would happily sit outside, watching ants and trying to follow them back to their colony.

    As an adult, I take people out to meadows with nets to catch insects and take a close look at them. It’s about trying to cultivate a childlike curiosity that people have lost or forgotten in daily life.
