I am in Oklahoma City, US. It's been 16 days since I installed a 5 frame nuc. My other frames have added wax and I sprayed them all with sugar water before installing the nuc. I haven't put on the honey super. Ive been putting bags of sugar water inside every week which the bees are consuming. My question is when I checked the bottom board of my screened bottom, I saw live larva. The frames were maybe 60-70% filled with capped and uncapped larva. Are these bee larva or some other larva on my bottom board? Is there any action I should take or leave them alone ? Thx
