Bugs: Nuk'em

Although I haven't noticed a lot of damage by bugs, I'm seeing more bugs in the garden.  I'm putting three types of organic pesticides on the garden as a preventative measure:  Safer Caterpillar Killer (Bacillus Thuringiensis (BT) / Kurstaki Strain), Captain Jack's Deadbug Brew (Spinosad (Spinosyn A and Spinosad D)), and Safer Tomato and Vegetable Insect Killer (Pyrethrins and potassium salts of fatty acids).  My garden neighbors have seen cabbage worms and cabbage worm eggs on their leaves.  I haven't seen them on my plants yet, and I'm working not to.  I'm a bit concerned that BT will affect my composting worms, but initial research says otherwise; I'll keep looking into this.
