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.

  • Study finds older adults could face harmful heat stress at just 1.5C of warming above preindustrial levels

    People aged 60 and over face dangers to their health from exposure to heat at much lower temperatures than previously thought, research has found.

    Older adults will bear the brunt of increasingly frequent sustained spells of extreme heat globally as the world continues to warm up, according to a study in The Lancet Public Health.

  • Vegetable and grain growers call for urgent action, warning of ‘catastrophic’ harvests due to continent-wide drought

    Successive intense heatwaves and an increasingly severe, continent-wide drought have left many of Europe’s farmers in an “unprecedented” crisis, with vegetable and grain growers in particular warning of “catastrophic” harvests.

    French vegetable production is down by “a very significant extent” compared with previous years, French growers have said, with shortfalls put at 25% for courgettes, 35% for lettuces, 40% for peas, 60% for broccoli and 50% to 100% for artichokes.

  • Nurses, medical experts and green campaigners reject party deputy leader’s dismissal of efforts to reach net zero

    Reform’s deputy leader has been accused of spreading misinformation after he dismissed efforts to tackle the climate crisis and urged British people to enjoy the warmth of the recent heatwaves.

    Richard Tice prompted a backlash from nurses, medical experts and green campaigners on Monday after he told a press conference he believed it was “arrogant” to try to stop the climate emergency, while encouraging people to focus on upsides such as better English wine.

  • The PM’s net zero pragmatism may please some voters, but as parts of the country go up in flames, it’s an increasingly hard sell

    When the siren sounded on Friday night, my first thought was fire.

    Weeks of unrelenting sun in the normally soggy Peak District, where I was visiting my mum, have bleached green valleys a dangerously dry, crispy blond. One of her neighbours had earlier pointed out an ominous cloud of smoke on the horizon, coming from one of the wildfires raging all summer on the moor. When that harsh, discordant shriek blared from every mobile phone in the house, I was half-braced for an evacuation order, not what turned out to be a faintly melodramatic warning to the nation to lay off the barbecues. A false alarm, of sorts, but one that felt uneasily like a wake-up call.

  • As warming seas push native species to cooler waters farther north, once-rare visitors have become more common

    ‘It sounds silly but I thought it was a person in the water waving,” says Kurt Lander, skipper of the Yellowfin charter boat, based out of Brighton. But when he grabbed his binoculars, he realised the fluttering movement he had noticed in the middle of the Channel shipping lane was a pair of sunfish.

    The huge fish were lying on their sides and flapping their fins. “Apparently, they do it as a visual attraction to birds,” he says. “They’re trying to get the birds to eat the parasites off them.”

  • Goyt Valley, Derbyshire: My patience into dusk is rewarded with a full display of unlikely calls and aerial prowess

    The setting sun spread a last Iberian glow over the hills opposite before they were drained of colour and sound, and by 9pm, the world was in monochrome.

    In line with national increases in their numbers and range, nightjars have prospered here recently. It seems especially so with the clearance of conifers, which has left a mix of old Scots pine and open space perfectly suited to this crepuscular ground-nesting migrant.

  • Robert Smith, Olly Alexander and Paris Paloma also among signatories to letter saying exploitation of Rosebank and Jackdaw fields defies climate reality

    More than 200 musicians including Massive Attack and Brian Eno have written to Andy Burnham urging him to reject plans for more oil and gas drilling in the North Sea.

    The letter, signed by 211 artists such as Bobby Gillespie, Olly Alexander and Paris Paloma, called on the prime minister to reject the Rosebank oilfield, warning that the project would fail to lower energy bills or provide energy security as most of the oil was likely to be exported.

  • Nearly a decade after fighting ended in northern Iraq, the climate crisis has brought extreme heat and a water shortage, making life almost impossible

    The first thing that strikes visitors arriving in Faka, a small village in Sinjar district, northern Iraq, is the silence. No children play in the streets. No shops are open. Roofless houses stretch across the hillside, their walls pockmarked by shellfire, while weeds and wild grasses grow through collapsed living rooms.

    A decade after Islamic State (IS) swept across the region, war remains visible everywhere. But according to the people who returned, another enemy has quietly taken its place.

    Rajab Mohammed says the problem in his village of Faka is no longer Islamic State but water and jobs

  • After trying nearly everything to prevent mosquito bites, I tested Biogents’ traps, used by the CDC and WHO, to find if backyard results are worth $200

    Don’t get me wrong: I’m a peaceful person with compassion for all earthly creatures. Except mosquitoes, which deserve all the swats, cursing and loathing they get.

    As someone for whom a single bite brings big, red, itchy lumps that last for days, I’ve done everything imaginable for relief. I’ve removed any standing water I could find, slathered myself with Deet, picaridin and eucalyptus oil until I smelled like a chemical waste dump, and worn hats, long sleeves and shirts soaked in alleged repellants, but none of it works.

  • It said that was what I was due after I submitted a claim for £300 for energy exported through my solar panels

    British Gas paid memore than £38,000 by mistake, then had no idea how to reclaim it. I receive quarterly feed-in tariff (Fit) payments for energy exported by my solar panels.

    In May, I submitted a claim for £300, based on mymeter reading, and I received an email stating that I was due £38,611.59.
