My corn snake is aproximately 6 months old, 18 inches and has shed aprox once a month over the past 4 months. s/he is in a 20 gallon standard with repti carpet, a water dish big enough for him to get fully submersed in and two hides, a hide made of stacked slate on the cool side and a store bought hide on the warm side. The floor temp of the warm side has been 85 degrees and the cool aprox 72 degrees. for the past 14 days the snake has appeared to be ready to shed and has had a small amount of skin come off in small patches. s/he looks like his/her skin is wrinkled in several areas. The humidity had dropped because of the use of my furnace so I have attempted the following remedies to address the situation

I added a 50 watt infra red bulb on top of the mesh lid over the water dish, this has made the temp of the cool side raise to 80 degrees and I add water every day to the dish

I sprayed the snake and the slate with warm water one time

I gave the snake a short bath in the sink yesterday

The snake has been in the slate hide all week and I have been handling him for less than five minutes everyday just to make sure s/he is alive. s/he has been eating a pinkie every five days and has continued to eat during this extended shed process

Any help/suggestions would be greatly appreciated

the temp on your COOL side is 80?!?! That's WAY too hot! And it's going to suck the humidity out of your tank, especially with a mesh lid...

What I would suggest is take a little sandwich-sized rubbermaid, crumple up a few paper towels in it, and douse them with water. Like, to the point where they are COMPLETELY sodden, and there's still a little bit of standing water. You want to aim for about 80-83 degrees TOPS for the water temperatue, and please use a thermometer, not your hand. What feels warm to you will most likely be well over 90 degrees, which is going to do more harm than good for your little corn. So, after you've gotten your little soggy-pt-filled sandwich container ready, put your snake inside and tightly close the lid.

Leave the snake alone inside the container for about 15 minutes, and hopefully by then the skin will be wet enough to come off, if not on it's own, with a little help from you. If there are patches already shedding, the skin needs to come off. Flaky sheds are the first sign that your humidity is too low, and your temperature too high. Corns should have temperatures ranging from low-to-mid 70's on the cool side to no more than 80-83 on the hot side. This is what I have found works best for my corns over the almost 15 years that I have kept them.

I also spray my tubs down pretty well the first day I see my snakes go into blue, and then I do a light spray every day until they shed. This way you're making sure that the shed skin is plenty hydrated enough to come off in one piece, but not heavy enough to cause issues, since the rest of it's cycle (read: the time when it's not prepping to shed) it just has a 'normal' humidity level. The ambient humidity level in my herp room usually stays between 45-55% year round, for reference...

there is also that commercial shed aid which I've heard works pretty well.

I just gotta put this

Thanks for the tips. I shut off the overhead light to cool down the cool side. I took a pillow case and wet it and placed the snake inside for about twenty minutes and returned the snake to his tank and placed the wet pillow case over three quarters of the lid. BTW the nippy little guy bit me when I returned him to his tank and drew blood in two places. I was suprised that a snake this small could actually break the skin. I have a BP that is about two foot long and he is gentle as a lamb. The corn has been nippy ever since I got it, everytime I place my hand in the tank it hisses and strikes. I will update everyone on the progress of the shed I hope everything goes well..

Well this might not help much since you say yours is biting but, what I do is get some damp paper towels and let my snakes slide through my hands while applying gentle pressure. Has worked everytime.
