Mustelids and possums

  • @Chris-B.

    Yeah we don't have an issue with rats in our house, caught a fair few mice, although not for many months.

    Surprisingly, when we had a few rats in spring, and they lived in the flax by my chickens, they weren't stealing eggs, so guess they had a decent food source from somewhere.

  • @taniwharugby Re Rats - Got any palm trees around? Pheonix in particular I think. A mate is a gardener and he said they are basically rat nests. Not sure if they can eat them but certainly like living in there. The neighbour has one and our cat just sits there and waits for a snack.

    We don't lose chook eggs to rats either, the girls will have a go at a rat - but not a stoat, they know they will lose. Apparently the shits just kill the hen and then only eat the heart. Hence me looking for answers on stoat killing (without using a car @Hooroo ).

  • @Snowy you do realise that once you eradicate all the rats, rabbits and stoats around your property your beloved moggy will have to target the birdlife?

  • @Crucial We will never kill off all of the rabbits. Thousands of them on surrounding farmland and they are his favourite. Really want to get rid of the stoats mostly.

  • @Crucial Got me thinking now (not always a good thing).Weren't mustelids introduced in the late 1800's to get rid of the rabbits? Thought that was why they were in NZ. That worked about as well as cane toads in Aus.

    Are there any examples of biological pest control that have worked and not just introduced a new pest?

  • @Snowy nah no palms, they live in flax bushes.

    I had 3 mice in my traps yesterday, but we don't have a problem that we see any of these pests, and as we have a new build on a concrete slab there is only one place anything can get in and an adult rat wouldn't fit.

  • @Snowy I can't recall the pest it is being introduced to deal with, but NRC have been granted consent to introduce some wasp to deal with another pest.

    Edit Just googled it, and is 2 insects to deal with an invasive plant.

  • @taniwharugby Hmmm. Wasps (German and common) were a great introduction the first time...(although accidental not biological control I think).

    This reed may be a problem but maybe creating another unforeseen one.

  • @Snowy yeah doesn't sound great, as far as I am concerned, wasps don't serve any purpose on this earth!

  • Massive history of biological controls causing issues or just not doing the job:
    Cane toads
    Koi carp
    Myxomatosis (sp?)
    Calici virus

  • @booboo Yep. Know of any success stories?

  • Nah. I think there just isn't enough known about how a new species will adapt and be adapted. Too many unknowns and the law of unintended consequences.

    you sound like you're running in the state election for One Nation

  • Faark off @mariner4life

    I'm not talking climate change.

    My point about to many unknowns was based was based on faintly remembered memories about the introduction of calicivirus.

    Farmers just wanted it lobbed in as soon as possible.

    Scientists wanted to hold off until they knew more and could maximise the effect.

    Was introduced unofficially and randomly and after initial decline we now have just as many bunnies but they're resistant.

    Koi carp were meant go be the shit when they were introduced.

  • @booboo What were Koi introduced to do?

  • @Hooroo said in Mustelids and possums:

    @booboo What were Koi introduced to do?

    Eat weeds IIRC.

  • problem with introduced species is that while they might like eating this invasive weed/pest in their homeland, they will just as easily find some native plant/insect to eat wasps are cnuts!

  • I maybe wrong about the koi carp. Goigle suggests they aee mainly escapees.

    I'm certain i recall some sort of carp introduced to the waterways in the Hauraki Plains which backfired. I thought it was koi.

  • @Snowy

    Monarch Butterfly, introduced to eat milk weed. Eats milk weed. Don't think it does anything bad...

  • I know that foxes were primarily introduced to Australia for hunting but it was also thought they would keep rabbits under control. Instead the booming rabbit numbers just meant more food for foxes and massive breeding.
