Here I am in the middle of a Tent Caterpillar infestation and am feeling
frugal.
My question is rather BT (Bacillum Thurengus SP?) will hold over a year or
so. I guess I will find out because I sprayed the critters with the old
spray, but if enough of you reply that BT goes dead in a year I will go out
and buy fresh BT spray.
Thanks, Ken.

I know I have used the same container of BT for 3 or 4 years and it
still seemed to be completely effective against cabbage worms.
I use the dry wetible powder form. I have the feeling you might be
using the liquid.

I have used the Safer brand liquid and found it to be good for several
years, but I have also had a Bonide brand liquid that never even worked the
first year I bought it. It had the appearance of being curdled and smelled
putrid. I think it had been frozen. Will that ruin it? The Safer stuff
had a sweet smell and a much smoother appearance.

They're living beasties.. I'd imagine freezing wouldn't do it much
good as storage at high temperatures wouldn't.. anything curdled and
stinking.. I'd say is dead.
