Those are good suggestions on that page. Your local garden center or nursery should have a spray with BT in it also. It's a harmless bacteria called bacillus thuringiensis. It naturally occurs in the soil and we eat it all the time in smaller amounts on our fruits and veggies (similar to the stuff in yogurt). Spraying leaves with it will eliminate any worms or larvae stage insects, because the bacteria attacks them...not us. Perfectly organic.

Yes, it looks like there are a lot of good options there, and I like the BT idea.
