it isnt chemical, it is biological. Bt israeli is a bacteria specifically for
mosquitoes, altho it knocks off midges as well. nothing else. Ingrid

What about dragon fly larvae? I wouldn't mind using Bti if necessary
(it's certainly a lot better than the IMO irresponsible idea of
fogging whole neighbourhoods with Malathion), but I would prefer not
to kill off the predatory insects as well (adult DF are a major
predator of mosquitoes). I didn't know that Bt strains could be
targeted by species.

Tangent: In the clueless-hysteria dept, some town council out west has
put a bounty on crows, as they are West Nile carriers. In fact, most
bird species are WN carriers; dead crows just seem to get used for
testing a lot (maybe the corpses get found more often because of their
size?). Wiping out crows would have negligible effect on WN
prevalence. Reinforces my prejudice that yer average municipal
council has less than one brain between them. Apologies to any
rec.ponders who may have served on council ;-).

Ingrid and Joann, and others. What would you say about the concept of using
a natural predator (goldfish & gambusa) against mosquito versus chemicals
(dunks)?
I would have expected this group to support the use of GF and like instead
of chemicals.
