Afternoon. Been lurking here for a moment and found a thread that relates to a problem i an having. Nymph dubia dieing and/or dissappearing. No matter my set up I get the same result of losing about 70% of stock. I currently have 18gal and 20 gal bins. Egg flats upright. Holes for ventilation. Temps between 82-85, humidity between 40-50. Always dry food and water crystals. I tried setting on heat tape, off tape. A little frass, no frass, 2" frass. Adding organic fruits and veggies, no fruits or veggies. Chicken feed, alfalfa feed, trout feed, mazuri feed. Dark bins, clear bins. Adults doing great. Finally got my stock up to produce 200k per month. When I put 2k nymph in a bin, 4k, 5k, 8k, 10k. Always getting the same result for the past year. Lucky to have 25-30% at the end of a month. Would enjoy speaking with someone....623.326.2134
