Should I be thankful for high humidity?

Just moved my Ball python and red tail boa from screen top tank to plastic tubs.
My acurite thermometer reads above 80%
Should I find a way to vent the moisture more or is this fine?

Forgot to mention that I havent sprayed at all and i just put cypress mulch as substrate.

I would vent it a little more. Just drill a few holes in the plastic a few at a time untill your humidity sits stable where you want it.

In the wild BP's usually hang out in very moist burrows or termite mounds, 80% humidity won't hurt your BP, just as long as any condensation doesn't cause mold growth (which I doubt you would have a problem with having cypress).
