Trichogramma wasps for pantry moths
I just bought some Trichogramma wasps to try to control pantry moths that had infested my mud room (probably due to bird seed and such). They arrived in 2 days on Wednesday, I kept them in my fridge for 2 days and put them out yesterday afternoon, one square in my mud room, one in my kitchen and 1 in the hall by the mud room. How do I tell if they are alive and doing their job? I have not seen any tiny wasps. I do see the dots on the squares. Thanks.
