I don't have a problem with my crickets smelling anymore since I changed the ventilation. I now keep them in a large 18 gallon rubbermaid with 4 inch by 6 inch holes on two sides of the container with small holes drilled in the top (I used to only have drilled holes and the smell was bad) I used a hot glue gun to glue aluminum screen ( not fiberglass because the crickets will chew through it) with proper ventilation it won't smell. I use an a hovabator incubator ( you can use heating pad, heat tape etc...) and place like 20 crickets (adults) in a Tupperware like 8" by 12" . Place in a smaller Tupperware ( I buy small round ones at the dollar store) like 3" or 4" very moist organic soil. I put in about 2 oz of water in the soil. Throw in a small piece of egg carton your gut load and some water bites(crystals) lately I have lined the Tupperware with paper towel to prevent babies from drowning in the water from humidity. Place them in the incubator ( or however you keep them warm) and measure your temps, keep them between 86 and 92 degrees. After about 5 or 6 days take out the adults and leave the container incubating within two weeks you should have your pinheads. It is good to open the top of the container like once a day or so to let in some air. Then when hatched I transfer my small crickets to another rubbermaid container and start over. I have been working on this for awhile and struggled a lot in the beginning and finally got it down. If you have any questions feel free to pm me. Good luck on your project
