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.

  • Scientists say unusually mild temperatures linked to low-pressure system over Iceland directing strong flow of warm air towards north pole

    Temperatures at the north pole soared more than 20C above average on Sunday, crossing the threshold for ice to melt.

    Temperatures north of Svalbard in Norway had already risen to 18C hotter than the 1991–2020 average on Saturday, according to models from weather agencies in Europe and the US, with actual temperatures close to ice’s melting point of 0C. By Sunday, the temperature anomaly had risen to more than 20C.

  • Research looking at tissue from postmortems between 1997 and 2024 finds upward trend in contamination

    The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study.

    It found a rising trend in micro- and nanoplastics in brain tissue from dozens of postmortems carried out between 1997 and 2024. The researchers also found the tiny particles in liver and kidney samples.

  • Mountaineers now scaling more peaks for first global study of nanoplastics, which can enter lungs and bloodstream

    Particles from vehicle tyre wear are the biggest source of nanoplastic pollution in the high Alps, a pioneering project has revealed.

    Expert mountaineers teamed up with scientists to collect contamination-free samples and are now scaling peaks to produce the first global assessment of nanoplastics, which are easily carried around the world by winds.

  • Open-net farms to continue despite numbers of wild fish halving as minister looks for ‘acceptable’ pollution levels

    Norway’s environment minister has ruled out a ban on open-net fish farming at sea despite acknowledging that the wild North Atlantic salmon is under “existential threat”.

    With yearly exports of 1.2m tonnes, Norway is the largest producer of farmed salmon in the world. But its wild salmon population has fallen from more than a million in the early 1980s to about 500,000 today.

  • As commercial monocultures increase, ecologists are calling for the remaining splinters of native woodland to be identified, protected - and expanded

    • Photographs by Rob Stothard

    “This could almost be part of Lapland, up here,” says retired researcher John Spence, approaching a clearing in the Correl Glen nature reserve in Fermanagh, near Northern Ireland’s land border with the county of Leitrim. “You could make a Nordic movie here and you wouldn’t be able to tell the difference.”

    Spence pauses to point out oak, hazel, birch, ash and alder trees, along with a series of rare “filmy” ferns, wild strawberry bushes and honeysuckle. There are well over 100 species of lichen in this small patch of temperate rainforest alone.

  • Newbury, Berkshire: From tracks in the snow to musky scent markings to vixens screaming in the night, it is hard to ignore fox mating season

    The sensory presence of foxes is woven through my days and nights lately – sightings, sound, smells, evidence. It is the mating season and, being largely solitary creatures, they are advertising their presence to one another in a manner hard to ignore; in a way that carries across dark, silent miles or cuts through the fumes of urban traffic. Foxy scent markings – musky notes of singed fur, sandalwood, spice and hawthorn flowers – bring me up sharp at a hole in a hedge, by a gatepost or anywhere down the lane.

    In snow, or in the creamy chalk soil that has washed out of gateways in recent storms, tracks give away encounters. Paw prints, narrower than a dog’s, that you can draw a kiss through without touching the pads, track slightly sideways, printing a straight, tacking running stitch across the land. Occasionally, tracks cross and run alongside one another for a while, or pool in a coming together.

  • North American native burrows into riverbanks causing leaks in canals and dams and carries crayfish plague

    It is quite a claim to fame to be the least wanted species in Europe but the red swamp crayfish, Procambarus clarkii, seems to have that distinction. It was picked out as a major threat to other wildlife, riverbanks and ponds in 14 countries to illustrate the efforts of a new Europe-wide organisation trying to eliminate alien species.

    So far this native of North America has only been found at 16 locations in England, including the ponds on Hampstead Heath in London, and more ominously in the Grand Union canal, which could give the crayfish access to a large part of the country.

  • Many homes are seriously damaged after torrential rain but residents know it could have been much worse and that they were ‘pretty lucky’

    Like anyone who has grown up and spent their life in the wet tropics of far north Queensland, Sonia Pollock is used to a bit of precipitation.

    “So we just thought it was rain at first,” she says of the torrential downpour around her flat in south-west Townsville.

  • Antamina, in the Andes, makes billions thanks to the green tech boom. But locals say they are being poisoned by arsenic, losing their water and sinking further into poverty

    A chilly breeze passes along the shore of Lake Contonga, 4,400 metres up in the Peruvian Andes. Julio Rimac Damian, from the nearby village of Challhuayaco, points to the mud under his feet. “All this used to be covered with water,” he says.

    A canal running from the lake that is supposed to carry water to lowland villages has also run dry. Damian says the water began to disappear two years ago when a mining company started exploratory drilling in Peru’s highlands.

  • CJ Taylor was pushing back a fire front when a wind change almost killed him. A new exhibition aims to recreate a flashover – and disturb the public into action

    The roar of an advancing bushfire, for those who have heard it, is often described as being as loud as an aircraft or an approaching freight train. “But my recollection was the opposite,” says volunteer firefighter and visual artist CJ Taylor, of the moment a fire burned over him. “Everything went quiet.”

    It was November 2019, and Taylor and a group of fellow South Australian Country Fire Service volunteers had been deployed to north-eastern New South Wales, near the Guy Fawkes River national park. They were trying to push back a fire front but a sudden wind change meant it was gaining ground too quickly.
