mosquito breeding control

 Anyone know of an Australian source for the bacteria (BTI) or the
hormone control for mosquito wriggles?  I searched online but can't
find any local web suppliers, i.e., in Aust, yet there are plenty of
outlets in the US.

A pool company has left a friend with a half-finished pool, and the
pool and the cratered yard are breeding plenty of mozzies here in
Sydney despite it officially being Winter. The mild temperature and
unrelenting showery weather are providing good breeding conditions.

The owner tried a couple of bottles of kero but it evaporated too
quickly to be a long-term solution (while awaiting a legal remedy for
the pool). Initially I thought a pool cover might provide the answer,
but I've been reading where pooled rainwater in the plastic cover
itself can provide a good breeding ground.

ALSO:

We might have some new readers since I last asked this question, so
I'll try it again: Some years ago I heard on a radio program of a new
(new to me!) method for stopping mozzies from breeding in garden
water features, lily ponds, etc., and I thought to myself "I should
write that down or I'll probably forget it." Well, I didn't write it
down, and sure enough I forgot the details!

This method didn't involve tiny fish or anything like that, either.
I just can't remember what it did involve; just that it was something
I would not have otherwise thought of.

Anyone?

 g'day john,

yeh i just did a google and didn't turn up much, they do have products
in teh USA that can be put in the water, maybe your friend may have to
purchase some online, check with quaranteen first to be sure they will
allow it into the country.

in the mean time why not add some native fish into the water guppie
type things we have many that are good ate eating the wrigglers and
eggs, there is even a shrimp.

yep we should write things down when we hear them hey? me guilty of
same.

up here the local gov' has these helicopters who broadcast some
product into the breeding grounds in the magrove areas, maybe you
could conatct them and ask what it is? maybe start with the sate gov'?
then try the moreton shire.

 not much help out there hey john,

especially for the purchase of the product(s), Bacillus thuringiensis
israelensis (Bti). would think this is what the local gov' uses? they
may be able to tell you how or where to buy it?

here is another product suggested:

methoprene

used in dog flea treatments as well.

how would using vege' oil go? it may not evaporate like kero' all that
is needed is th stop their access to oxygen, that's all the kero'
does.

Yes, those are the two I was chasing up.


That's a thought, but oil that is never going to evaporate may
cause problems when it comes to tiling, etc. I expect it would
soak into the concrete walls and floor. They do pump as much water
as they can out of the pool from time to time, but wrigglers only
need the remaining few mm to survive in. Then there is all the
water pooled in the churned-up yard, too.

I think the BTI would be the best, if it works as described in the
literature.

Thing is, we're not Robinson Caruso here. There must be hundreds of
people facing the same problem at this very minute. I'd be surprised
to learn there is no local availability of the above commercial
products.

Thanks for your suggestions.

that's a point john, cuts the options down as kero would also leave
some inbedded residue in the unsealed cement.

i did think of pumping but imagined that would already be being done.

not sure how cheap we can keep this but the ponding in the yard get
some cheap as sand or whatever and fill all of them in.

you can buy the bti online what i saw it wasn't cheap, there again as
it is coming from overseas talk to customs first if that is the way
that is decided.

how about once it is pumped as much as can be (and we are coming into
our dry period now for the east coast, if news paper or cotton rags
wher sued to soak up the remainder of the water? they could be left in
the pool and then pump when excess water appears.

have they talked to the local council yet? try to do it in a way where
they may not need to identify who has the problem or where, they may
point you at a local product? did they check produce agencies they may
ahve product.

also hope they triumph and get the pool finished.

a thought that just crossed me, we have a salchlor pool, how come
mossies don't breed in a finished pool? is it because of the salt
and/or chlorine??
