If your washer and dryer are anything like mine, they'll wind up killing your snakes. The vibrations caused by the intense spin cycle will drive your snake nuts, or knock the cage over. Mine managed to knock a large TV (An older, heavier one that isn't flat screen) off of an entertainment center the next room over. I wouldn't even think of putting my BP in there. Yours aren't the same as mine, of course so it really depends on the power of your machines.
oh ok then the temp in there should be like the rest of the house except when the dryer is going.
Next time you run the dryer, put a thermometer in there to see how hot it gets, before moving, you may have to adjust some of your husbandry.
