Frank from Broken Arrow, Ok writes

What is the shelf life of Monterey B.t. Insecticide?

I have a bottle of concentrate that is nearly 5 years old. It is the color brown. Will it still be effective?

Answer:

Monterey B.t. Insecticide will last about 3 years once opened as long as stored correctly. Keeping it out of extreme temperatures & out direct sunlight. If the bottle was already open, we would not advise using a 5 year old bottle
