Netted the girls to prevent budworms - thoughts?

BT is a soil-dwelling bacterium. Organic. Spinosad is organic as well.

the problem I had last year was by the time i knew I had budworms there wasn't any bt or spinosad to be found. Then I foolishly thought if I really hunted I'd find it and I couldn't get my hands on any. If I have to go that route I will. Even though they are organic, they're still synthetic and I'd rather avoid it if I can but if I can't I'm going straight to amazon and ordering it.
