Hi

I am just starting on the dowsing course.
I have placed a few cures around the house but how can I protect them from pest control? The pest control comes every couple months.I don't like to put tape on the cures.Once I did tape a cure and then I needed to move it a couple inches and the tape picked up the dirt even when the place was clean.And when I tried to take it off It seemed to me that color of the dowsing stick is coming off.One more thing If the pest spray gets to the cure would that lessen the power of the cure in any way?
