I have a biopod I've been using now for 4 months. I was putting as much as 10lbs of food in the bin but getting less then 1lb of grubs a day, mostly 1/2lb. For the last several days I've been getting nothing. I live in Hawaii and feed them mostly bananas and papyas. The grubs are active but I'm getting nothing in the bucket. Biopod is almost completely full of digested compost, I feel like I'm going to have to empty compost soon. Pederator? Geckos get in the biopod. Any advice whats going wrong?
