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.

  • Figures show domestic flower growers are expanding their market share, as the government gives sector official recognition

    British flower farmers have long resembled David faced with their own particular Goliath – the imported flower industry. More than 80% of cut flowers bought by UK consumers are shipped or flown in. However, recent figures show domestic growers are expanding their market share.

    Chloë Dunnett, the founder of Sitopia Farm, a London-based organic farm growing food and flowers, says: “Our flower sales are up 65% for the year and turnover is increasing year on year as the public and florists look for flowers that are seasonal, environmentally friendly and hyperlocal – consumer power can be very effective.”

  • The US, Russia, Iran and Saudi Arabia – some of the highest oil-producing nations and major greenhouse gas emitters – opposed the measure

    The UN has voted 141-8 to adopt a resolution backing a world court opinion that countries have a legal obligation to address climate change, with the US – which is the world’s biggest historical emitter – among the small group opposing it.

    The UN secretary general, António Guterres, said Wednesday’s general assembly vote, in which 28 countries abstained, underscored that governments are responsible for protecting citizens from the “escalating climate crisis”.

  • Phenomenon, often seen around Britain’s coast at this time of year, is caused by a combination of algae and weather

    At this time of year a sinister-looking substance can often be sighted around Britain’s coast: a frothy foam piled up along the shoreline or appearing in long ribbons offshore. People sometimes assume this foam is the result of pollution or sewage dumping. In fact it is a common natural phenomenon produced by a combination of algae and weather.

    Sea algae start to grow in April as conditions warm. The most common sort, phaeocystis, is not toxic and forms part of the marine food chain. When the algal bloom dies it leaves a brown scum of organic material with surfactant properties, which, like soap, lowers the surface tension of the water.

  • Willington, County Durham: On a fine May morning, there’s no better time to look at the stunning array of ways that bees and flowers have co-evolved to interact

    “It is a truth universally acknowledged, that a wild flower in possession of a fortune in nectar and pollen, must be in want of a pollinator,” Jane Austen might have written, had she been a botanist. All along this former railway line, on a sunny May morning, there are thousands of newly opened flowers laden with such inducements, vying for the attention of foraging bumblebees. And none delivers its pollen with such deception and violence as broom (Cytisus scoparius).

    A large bumblebee arrives, settles briefly, finds no nectar and departs, leaving a deranged tangle of stamens protruding from the petals. What happened? Poking my finger into an intact flower, to mimic the visitor, there’s an explosion of pollen as 10 stamens and a coiled stigma, confined in the boat-shaped keel petal, break free. Simultaneously, they deliver and collect pollen, with a gut-punch to the insect’s furry abdomen. Bumblebees don’t seem to mind; the trap has been tripped in almost every flower on this bush.

  • Environmental activists lock themselves to pesticide barrels in protest outside Syngenta headquarters

    More than 40 people, including Greenpeace UK’s programme director, Amy Cameron, have been arrested after a protest outside pesticide company Syngenta’s Yorkshire headquarters.

    A number of the activists locked themselves on to 15 blue pesticide barrels outside the headquarters, blocking the gates and leading to the temporary closure of the local A62. Activists had transformed a roundabout outside the front entrance into a giant hazard symbol carrying the message “Syngenta poisons nature” with an arrow pointing directly at the building. The action took place on World Bee day.

  • Global study finds wrappers, bottles and lids on shorelines of 93% of countries analysed as UN talks to tackle issue in turmoil

    Plastic food wrappers, bottles, lids and caps are by far the most common items of litter found on the world’s shorelines, a study has found.

    Researchers looked at data from more than 5,300 surveys of coastal litter to produce the first global analysis of its kind. They found the data in 355 existing studies on the subject.

  • What does a surge in ocean temperatures, compounded with El Niño, bode for the summer?

    An enormous marine heatwave off the US west coast is ringing alarm bells among ocean and atmospheric scientists as new data shows its ecological and environmental effects are intensifying.

    The unusual area of warm water has persisted since peaking in size during September 2025 and still stretches thousands of miles from the California coastline – more than halfway across the Pacific – affecting a vast triangle-shaped region of oceanic habitats from Hawaii to British Columbia and southward to Mexico.

  • Authorities are cracking down on rights activists fighting for Indigenous people threatened by authoritarianism, extractivism and climate breakdown

    The operation began at 9am Moscow time, but took place across all of Russia’s 11 time zones. Almost simultaneously, agents of the federal security service (FSB) raided the homes and workplaces of 17 Indigenous rights activists.

    Officers carried out searches, confiscated laptops and phones, and arrested and interrogated activists about participation in international forums. Most were let go; many have since left the country. Others remain in Russia, but will no longer speak up.

  • In the country’s north, mining has ravaged Indigenous lands and lives for decades. Is history repeating itself as renewable energy schemes arrive on their doorstep?

    In the heart of the dry tropical forest, Maria Elena Aguilar Uriana walks past towering cacti, her ancestors’ graves, and patterned clothes blowing in the wind. Her brow is furrowed, her hands fixed on her hips. She points to a former watering hole, now nothing but dust.

    “Our children are malnourished and dying,” she says. “It’s all because of the mining. It has destroyed our landscape, our homes, our lives.”
