Not too often and not where they poop the most, I wouldn't. That area should be pretty moist if you let it build there and just bury the feces.
In other areas where it is more dusty, it doesn't hurt to wet it some to provide moisture to the layers underneath. When I empty out dirty water at times I'll pour it out in one corner, or along the wall, and cover it over with dry bedding to retain the moisture, during hot and dry parts of the summer.
