The main difference is the amount of "knockdown" power that they have. Both products contain PBO, which is a quick knockdown product. CB-40 contains 1% PBO, and CB-80 contains 4% PBO. So CB-80 is considered to be a stronger knockdown product, basically meaning a quicker kill. You would want to use CB-80 for cockroaches and spiders, scorpions, etc. If you are just dealing with flying insects, CB-40 would be fine.
