anyone have a problem with them and what can you do to stop them from infesting a colony?. just noticed one of my colonies is seething with them...

By the sounds mealworms and their beetles can eat the mites. But I would just take everything live out and replace all the substrate/clean the containers to get rid of them.

I had a similar mite problem with my wax worms and they infested my whole room, never got to the mealworms though that were in the same stack.

Haha

been doing so much research on this.

i finally have a set up where the mites havent come yet!

the answer

1) heat

2) right moisture

mites i believe like high moisture,

but mealworm eggs require high moisture to maximise hatch rate.

so, HEAT is key.

though sites say 27c is optimal or max, not true.

i have read articles that higher 28 to 30 is also achievable.

mites, can breed in thousands in days.

i keep my 'breeding bran' at 28 to 31c steadily.

using 2x bbq foil tray and a 7w heat matt by reptile one ($27 from hff last time)

what i do is ensure there is lots of bran - 1kg per laying tray.

in that i have approx 300 beetles.

LOTS Of veges so the bran and the beetles have moisture, but the heat kills the mites, they dont like the heat.

so the moisture is fine IF you have heat,

cos moisture will evaporate but the eggs and the beetles dont eat their eggs as they ahve plenty of food, eggs get moisture from veges too trapped in the bran, and the mites die with heat

beetles WILL eat mites, to a degree.

mealworms will eat it too, IF the mealworms are big enough a nd there is enough fo them.

so once you have 3 to 4 mm mealworms in the bran, (when you turn the bran over, you see constant movement leveling out the bran) you should have a 'critical mass' to be immune to mites.
