I drilled a small hole in the bottom of my container I am rearing one of my beetle grubs in to let excess water drain out from when I moistened the media. My grub found this hole 2 days ago, and although he can't fit through it, he has been biting at it non stop for the past two days ( it's making an annoying clicking sound). I'm not worried about him escaping but I am a bit worried about the fact that he hasn't given up. Should I put him in a new container, or will he eventually give up??
