if i were you i would put some hot glue in each hole making sure u fill the holw, then sand off the exta and bam hole fixed. Remember to take the snake out and dont use anything toxic.
Agreed with cinderbird. I made that mistake with my bp and now he has got a very very very mild case of scale rot( like 5-6 scales on whole body, mostly on under chin) and it actually sorta tore off the outside coating of a lot of scales. The stuff that came of kinda looked like shed skin. I'm sure he will be ok after a shed, but I wouldn't use ductape.
