These are pellets made from crushed and compressed coniferous trees. The coniferous species used this time is Japanese cedar (Sugi). Are you tired of your mats getting soggy quickly? These are recommended for beetles and large stag beetles, which are prone to this problem. They expand to about 3 times their volume when they absorb water, but they last longer if you lay them down without adding water and let them absorb insect urine and spilled jelly, rather than adding water beforehand. However, there is a limit, so replace them when moisture starts to seep out. Also, for small stag beetles, it can get too dry, so instead of pellets, mist the stag beetle itself about twice a week. They will be shipped in a plastic bag, size 80. Free shipping. It is listed as 5kg, but we will roughly pack a little more than that. #stagbeetle #Hercules #stagbeetle #beetle #Japanesebeetle #longhornbeetle #substrate #mite #antimite #food #jelly #soil #mat #insect #cricket #roach #chinchilla #cat #toilet #pellet #deodorant #additivefree #wooden #smallanimal #substrate #safe #foradults #adultmat #management #easy #odorcontrol
