How do I get rid of grain mites?
1. Lower your humidity down below 30%. If you don't know what your humidity level is, get a hygrometer:

- SensorPush HT1 Sensor - this is what I use, I love them! (affiliate link, thank you for your support)
- Put split pea flour in the impacted bins.
- Use a "10% split pea flour to substrate" ratio. If you have one pound of substrate in your tray, add 2 ounces split pea flour directly into the bin.
- If possible, place a split pea flour barrier around your trays. I even spread split pea flour on the floor, but I'm on concrete.
- Split pea flour is available at specialty grocery stores or online. If you have a grinder, you can try buying dried split peas and grinding them, but it needs to be a very fine powder.

4. Follow a new moisture feeding routine:
- Every two days, add your moisture source to the impacted bins.
- Wait 2 hours to let the mealworms feed.
- Remove ALL remaining moisture sources.
- Repeat for two weeks or until grain mites are gone for one week.
Treat your substrate.
- Deep freeze your substrate for 48 hours.
- Bake your substrate at 175 for 20 mins. The internal temperature needs to be 175.
Maintain humidity around 50%. You can run higher humidity if you are very disciplined about treating your substrate, and have split pea flour ready.
