The article said Bt sub-species. Not likely talking about Bt-i.

I read a while back that there was concern about its toxicity to bees....
From what I can find now there is only one species of bees that it is highly
toxic to. Others may suffer a shorter lifespan but not one that anyone
seems concerned about. It certainly seems the case that the cost/benefit
ratio is on the side of using it. I still like guppies better though... DK

regular Bt will kill any caterpillar. Bt israeli will only kill mosquito
and midge
larvae. Ingrid

small water gardens (barrel size). This year I put in 2 guppies which I
will now have to bring in for the winter since they are tropical....
Anyone
want some guppies (now 3)?
