Mealworm farm question

[Cluckering around]

So several months ago I decided to start my own mealworm farm so my flock could have fresh treats. I'm finally getting babies, but there is a web like substance in the "nursery" bin. Do the babies produce this, or do I have an intruder?

It's moth eggs, you have an intruder.
