My bedroom has lots of chingchoks, which I don't mind as I understand they eat mosquitoes, which probably explains why my room, which is adjacent to greenery and has open (non-glass) windows, is very mosquito light. However, I've noticed three chingchoks recently recently, that lost their fear of me, slowly stopped moving and eventually died (at least the first two did, the third is in the slowly losing movement phase). Anybody know what's going on here?
