Johnny, I get 500 crickets at a time. For both 3 week and 4 week. Average humidity I have no idea. I did not realize that was important. Do they need higher or lower? My container doesn't have a screen top, but i has ventilation slots all around the top part of the lid. Maybe that is not adequate??

Tom, I will try to remember to remove dead crickets. They can't be too sanitary if they stay in there for long periods, I agree. And thanks on the alliteration-with my daughter watching over my shoulder, I try to make the effort!! Now she is laughing at me....
