This is what i just saw since I don't have Mylar on the sides of my terrarium yet to keep it warmish I used a towel then after oa couple of weeks I noticed some tiny grey bug on the side of the tank now I put foil around my tank for temporarily and don't know what is going to happen. If the stupid bugs come again what should i do also i think it is because of the light.I want to get rid of the bugs without killing them because then I will feel sorry because of Religous Reasons.
