" In waters with no fish at all BT is usually broadcast as granules on
the water surface.


What???
Bt does not harm fish.......Its a BI..........Been using it for years...Bt
is a bacterium that causes disease in some insects (mainly mosquitoes), but
does not harm other animals or plants...OP's and CB's are the ones to look
out for...Check your chems in the dunks you buy....Bt is the good guy...If
it has Carbofuran in it, that's a no-no.......Pyrethroids are a no
also..They are absorbed into bottom muds & silts and produce fish kills in,
obviously, bottom feeders...OP's can bioconcentrate in aquatic life and pose
a hazard to their predators as well....
