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.

  • Female named Rounder surrounded by family members when about to give birth to her second calf

    Scientists have managed to film a sperm whale giving birth while other female whales worked together to support the mother and her newborn.

    A team from Project Ceti, an international effort seeking to understand how whales communicate, was in a boat near a pod of 11 whales off the coast of the Caribbean island of Dominica on 8 July 2023.

  • National Trust says one year after reintroduction they are enriching habitats and may be having kits this summer

    They were released this time last year with fanfare, much hope and also, perhaps, a little trepidation.

    Twelve months on, there have been ups and downs for the first beavers to be (officially) reintroduced into the wild in England since the semiaquatic mammals were hunted to extinction 400 years ago.

  • Conserving the watershed of the Tana and improving farming methods is securing water supplies and livelihoods alike in a changing climate

    When in 2017 David Nyoro became one of the first farmers to partner with Africa’s first water fund to conserve the watershed of Kenya’s biggest river, he received 180 high-value avocado seedlings. The 67-year-old’s farming methods had been dominated by annual crops that left large sections of his five-acre piece of land bare, increasing soil erosion and contributing to river sedimentation. “We used to lose a lot of topsoil to the river. Such loss of soil nutrients and poor farming practices meant we had less farm produce,” he says.

    The avocado seedlings enabled him to grow his farm income to close to 2m Kenyan shillings (about £11,500 at today’s exchange rates), with each mature avocado tree yielding 70kg (154lbs) annually. He introduced cover crops to improve soil health and reduce soil erosion and sediment loads.

  • Number fell 23% year on year in 2025 but waste companies say recycling systems still under strain from sheer volume

    More than 6m vapes and vape pods are still being discarded every week in the UK, with waste management companies warning the sheer volume continues to strain recycling systems despite the ban on disposable e-cigarettes.

    According to research by the recycling campaign group Material Focus, the 6.3m vapes and pods thrown away each week in 2025 represented a 23% reduction from the previous year.

  • Lots of us aren’t very keen on bats. But the more we find out about them, the more amazing they turn out to be

    Bats have a bad rep: in a recent survey by the Bat Conservation Trust (BCT), 46% of people expressed negative feelings about bats. But just look at them! Bat carer Liz Vinson, a volunteer with the BCT, calls them “little furry humans with huge jazz hands. They have individual characters: some are divas; some are bone idle.”

    Shirley Thompson, BCT’s honorary education officer, has been championing bats since the 1980s. “I still think they’re magic,” she says. “The more you find out about them, the more you realise what amazing creatures they are.”

  • Strikes on oil facilities burned thousands of tons of stored fuel, producing a pall of toxic smoke

    Black rain fell in Iran earlier this month, a grim phenomenon seen previously in other war zones.

    Strikes on oil facilities burned thousands of tons of stored fuel. Unlike the clean controlled combustion inside an engine, uncontrolled burning leaves many particles of unburned fuel, producing a pall of toxic smoke over affected areas.

  • Driving fast is in ‘the German DNA’, say lovers of the speed-limit free Autobahn, but support in the country for a restriction is growing

    Death-defying thrills are not what draws Lutz Leif Linden to zip down the Autobahn faster than a plane taking off. Instead, the feeling of freedom and an appreciation of technological mastery play a part in his “almost loving relationship” with driving cars faster than most people can imagine.

    The top speed he has reached on the road in Germany, the world’s only democracy without a blanket speed limit on motorways, is 400km/h (249mph). “It’s like an airplane,” said Linden, the president of the Automobile Club of Germany (AvD). “You are faster than an Airbus at start.”

  • This labor-intensive way of eating isn’t for everyone – and I’m not sure it’s for me. It requires planning and flexibility

    When I called Robin Greenfield, an environmental activist and author, his assistant answered. “We’re stopped really quick,” Marielle said, adding “he is harvesting a ton of wild onions right now. He’ll be on in just a minute.”

    I waited, curious to see his haul and bemused by his willingness to delay an interview for wild vegetables. I had called Greenfield, who wrote Food Freedom about the year he grew and foraged 100% of his food, to talk about how possible, or hard, it is to do just that.

  • Rena Effendi’s film Searching for Satyrus began with a quest for the endangered insect that bears her family name. Before long, she was reckoning with secrets, lies and the mysterious life of her wayward dad

    High in the Caucasus mountains, the photojournalist Rena Effendi is searching for the butterfly that bears the name of the father she hardly knew. It is rocky, bleak, beautiful – and impossible. The grass is fried yellow by the increasingly fierce summer sun, the butterfly’s food has been grazed by sheep and, if it exists at all, Satyrus effendi usually flies only as a single insect across a square kilometre of rock, scree and slope.

    A butterfly hunt makes an unlikely subject for a prize-winning documentary, but Searching for Satyrus is a gripping quest that reveals a remarkable part of the world little known to western audiences while examining issues from war and nationalism to global heating and extinction. Ultimately, however, Effendi’s search for her father’s butterfly becomes a moving reckoning with the secrets and lies in her family and the life of her wayward father.
