Is year old BT and Spinosad still effective?

I have leftover Southern Ag BT and Monterey Spinosad that I bought last year. It’s been in my garage prolly cooking above 100 degrees frequently. It’s prolly not prudent to use, but I was curious what this community’s experience has been.

Monterey BT will normally last a year, although I keep mine in a kitchen cupboard so it's not exposed to light or excessive heat

I've never used Spinosad so can't comment on that
