Jane, I have been interested in using these wasps for moth infestation treatments in the past. Unfortunately, I was informed that if you don't place them near the infestation site, they will not find the moth eggs. Now maybe this was one person's experience, but I was hoping you could briefly describe how you used them and how effective they were.
