Very close to the point of almost hair splitting.
BTI = Bacillus thuringiensis subspecies israaelenses
It is actually the toxins that are produced by the bacterium that do in some types of mosquito larva (mostly Aedes species which are our bane). This toxin is termed delta-endotoxin. It will also work quite effectively against fungus gnat larva.
No toxicity to fish, birds, non-target invertebrates, pets, wildlife, people, or plants.
I find integrated pest management to be very exciting. For anyone interested. check this link,

Tre, no problems with Utrics to the best of my knowledge. They would be deemed a plant. I will use them in the pond that I am transferring aquatic Utrics to.

Not the time or the place but if your sphagnum peat bog is really connected to your pond, you are going to have difficulty stabilizing your water and you can probably kiss clarity good bye. You will have some of the wildest KH and pH fluctuations you have ever seen and additionally, you will most probably have problems with string algae capable of out competing your Utrics as well as numerous other issues. Do you really have a sphagnum peat bog connected to a pond? What kind of mechanical and bio filtration are you using? I don't know of any filtration that exists out there capable of encouraging a suitable habitat for nitrifying bacteria that is vital to pond health for that type of a set up.
