Yup

From my research a normal household deep freeze will not go low enough to kill mold spores, it makes them dormant while they are frozen but does not kill.

Mold likes two things, warm and moist. The best way to keep away from mold on your sticks is too watch you temps and RH.

Oxygen-rich environments with humidity over 70% and temperatures above 60 degrees Fahrenheit are ideal for mold growth.

Keeping boxes closed (so no spores get in) and maintaining your RH less than 70% (my preference is 64 to 66% but YMMV) and temps sub 70F is the best way to avoid it.

regular inspection (especially of freshly received over-humidified sticks) can catch mold early and it can simply be wiped off with a soft rag, paper towel or soft bristle brush.
