Hi Steven –

We do not recommend storing trichogramma wasps for much longer than a few days. Keep in mind that the longer they are stored the higher the mortality rate will be.

How to Release:
• Shipped as pupae in host eggs, glued to one inch by one inch paper squares, trichogramma arrive ready to hatch out as adult wasps.
• Release when moths are first present and periodically thereafter.
• Use 5,000 parasites (1 square) per 5,000 square feet weekly, or every other week for 3 to 6 consecutive weeks.

Hope this helps!
