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.

  • Prime ministers of Australia and Iceland discuss effects on their countries even as some shy away in face of war and inflation

    World political leaders are descending on New York for the UN general assembly and some of them are putting the climate crisis on the agenda as they spoke on Monday at the start of the city’s annual Climate Week.

    This year’s Climate Week – which runs alongside UNGA – comes after months of extreme heat in large parts of the world including Europe and the US, wildfires in Africa, flash flooding in Asia and a record-breaking El Niño.

  • Scientists found unequal impact of the climate crisis would not be reversed even if implicit goal of the 2015 Paris agreement is achieved

    The unequal impact of the climate crisis on the world’s poorest people, including those in tropical areas, has been highlighted by new research that finds they will be among the last to feel the benefits if global greenhouse gas emissions are cut to net zero.

    Temperatures have risen more significantly in tropical areas relative to their historic range than at higher latitudes, including in wealthier countries in Europe and North America.

  • EVs with 90,000 to 120,000 miles on the clock are more likely to pass MOTs than petrol models of the same age

    Motorists buying a secondhand car with a lot of miles on the clock are likely to find an electric vehicle (EV) ultimately more reliable than a petrol vehicle, according to a study.

    An analysis of 47.4m MOT tests found that after cars were driven 90,000 to 120,000 miles, EVs were about 25% less likely to fail than petrol models of the same age (based on a failure rate of 16.5% versus 22.1%).

  • Forestry England invites people to help it create a record of when and how the season arrives across the country

    The reds and golds of autumn leaves may be beginning to appear, but exactly when the season arrives is not always as predictable as the calendar might suggest.

    Now, Forestry England is asking people to help track the changing colours of forests to create a record of when and how autumn arrives across the country.

  • The Argiope bruennichi, spotted in Cheshire for first time, part of worrying trend that could threaten native species

    She is an unlikely harbinger of the climate emergency: a venomous black and yellow spider who spins mysterious patterns in her webs and eats her mates for breakfast.

    Native to mainland Europe, north Africa and Asia, the Argiope bruennichi – commonly known as a wasp spider – is rarely seen in the north and west of Britain. But a fully grown female has been spotted in Cheshire for the first time by conservationists from Chester zoo, who stumbled across the large, brightly striped arachnid in a rewilded field.

  • New study finds subsidence caused by groundwater extraction can take place as far as 20km from site of mine

    The impact of opencast mining goes far beyond the edge of the pit. Studies of an opencast coalmine in western Germany show that opencast mining triggered extensive subsidence in the surrounding area and re-activated dormant geological faults.

    Underground mines are often associated with ground subsidence, but less is known about the risks associated with opencast mines. Researchers from the GFZ Helmholtz Centre for Geosciences in Potsdam, Germany, studied satellite data and geological field measurements from the area around the opencast Rhenish coalfields, between Aachen and Cologne.

  • New rice varieties give hope that farmers can overcome the climate emergency and a warmer future that threatens harvests

    When schoolchildren in Shiroishi were enlisted to plant rice seedlings in June, Shinto priests blessed the land and asked the deities for a bountiful crop. Judging by the fields behind farmer Haruki Kawasaki, their prayers have been answered.

    The 63-year-old is preparing to harvest this year’s crop of hinatamaru, a variety of rice whose plump grains have thrived despite exposure to another hot and dry summer, conditions that typically punish rice yields.

  • Before his final general assembly, António Guterres speaks about why he put climate at the centre of his UN tenure

    António Guterres, who will finish his second term as UN secretary general on 31 December, has spoken out more strongly on the climate crisis than any of his predecessors. He has criticised “immoral” fossil fuel companies for their “grotesque greed”, warned that we have “opened the gates of hell” and hailed the new “clean energy age”.

    Before his last UN general assembly, we asked him about making the climate crisis one of the top priorities of his tenure.
