Advertisement Hello! So about two or three months ago I got a adult (I think, this is what the seller told me) Telodeinopus assiensis. Since I had him he had to go through way too much housing because of mites but now I'm setting up a bigger terrarium for him and this time (unless mites come back..) this will be on the long term. So I got some: Fiber coco (I can't get anything else), 45x45x30 terrarium, leaves and dead woods. I plan to get him live with my sun beetles (if it's okay) and their larvaes, and provide hides etc. Now I have a few questions: First of all the wood. I got some rotten wood but some of this wood had little white things crawling on it, is it still safe to use it? Also, on some wood I saw snails, isopods, but on some nothing but I mixed all the wood together so now I don't remember which one had isopods on it and which one had not and I 've heard that this is suspect if a piece of wood does not have any bugs (except the little white things) eating it? Also wondering: So the terrarium is gonna be in my room, and the pieces of wood that I got have mold on it (obviously as it's rotten and wet), could it be bad for me or it's all fine if it's in a enclosure? Another question is: how do we sterilize it? And do we sterilize it fully or not? Too afraid of mites and other bad things but also read that having it fully sterilized can cause problems? Something else I was worried about is my milliped in itself, I had him since three months like I said but since I had him I've never saw him burying himself in the ground, maybe that it's because of the 'too frequent rehousings' I made him go through and that stressed him out, but is it normal or not? Most of the time he is either moving or just sleeping in a coco hide. Is it also a problem if I house him with my sun beetles, and for my beetles I provide beetle jelly and the milliped have his leaves etc but still eat often the jelly? I also collected moss in forest: should I sterilize it or not and can this be dangerous to milliped-beetles-roaches or just insects in general? I wanted to make it grow in the terrarium on wood but don't know if this could be bad for them if they eat it or something like that? In a few months as well I'm probably gonna get some other species of milliped such as Archirostreptus gigas, Ophistreptus guineensis, Anadenobolus monilicornis, but I saw people putting different species of milliped in the same terrarium and I was wondering, if the terrarium is big enough could I put different species together or it's better not? Also, the temp in my room is about 20/21°C to the lowest this winter, and I have a 5w heatpad, should I use it or not? I have mantis (Hierodula Majuscala) and they are not heated for now and as I have only one heatpad I wonder which one I have to heat the most, sorry if it's a stupid question. Also how strong a 5w heatpad is? I have a really hard time keeping humidity high, I spray a few times per day but this is probably too much but even like this it still doesn't want to stay wet. Does this have to be wet the whole day or just sometimes? Does the litter of leaves etc need to be wet or just the soil? When I spray, I generally avoid to spray on my milliped because it scares him, is it fine or he needs to be sprayed? This is an ExoTerra terrarium so lot of ventilation but I'm afraid that if I put a plastic something on top of it to keep humidity in, it will become too 'stagnant' for my animals. Generally the fiber coco stay moist only a few days after I put it in for the first time and that's pretty much it Then last question; the grain mite. This all started because of something rotting in the mealworms enclosure and then I had it with my milliped, they were on the leaves, the ground, eating the mold on the wood, getting on him, to the point where for a whole week I had to put my milliped in a 'quite dry' place because the mites were coming back everytime even after rough cleaning and precautions with the food. Now, I almost don't see them, only like two crawling something but this still scares me. With rotting woods, dead leaves, humidity are the mites going to make a come back?
