If they are wood or ceramic, I would bake them for 30 minutes. Kills any bugs. If plastic, I would use either F10 and / or diluted bleach solution. Should kill and disinfect plastic items. Hope this helps.
I'd go with baking though, it's easier. 180 for 20 mins should do the trick. Kills snake mites on wood too.
What he said ^.
If wood mites concern you, switch to paper-towel or you could bake the substrate as soon as you bring it in and store it in a sealed tub for use later.
I can't guarantee the last bit but, I see no reason why it wouldn't prevent new wood mites from calling your enclosures home.
Well I think they are wood mites because my corn snake still eats. Plus I never see them crawling on him, and I don't think he has any bite mark. I saw them beneath his water bowl, and I don't even know how he could have gotten them. Are these wood mites or regular mites?
Sounds like wood mites, but a pic would really help. If you are using regular cypress mulch its a good chance they are regular wood mites. The dreaded parasitic mites you get are tiny little black bugs and wood mites can be off white to yellow looking from what I have seen. Hope this helps.
