Two quick notes for you sweetcheeks.
1. If you are buying those boxes of crickets that have the food in them you can put the opened box in a small kritter keeper (or dump the contents and toss the box) and the crickets will stay alive for up to about 2 weeks or so as long as the moisture block part of the food does not dry up. This will allow you to space out the insect feedings rather than feeding so many at once.
2. The Repashy diet will last for a few months if well sealed, but if you are wanting to keep it for longer it will stay fresh for up to 6 months in the refridgerator. After 6 months in the refridgerator any unused food should be thrown away and replaced with fresh food.
