Last winter my multitool collection consisted of a Squirt S4 and a Wave. Easily kept in the house

As my 'collection' has expanded over the year I too have my own red drawers that live in the shed and house my meagre collection. I have noticed the odd rust spot appear and I can only assume it is the coldness, etc. in the shed.
So my question is would a handful of silica gel sachets in each drawer help the situation?
Like these:

I kept the ones that came with my Maxped bags and they have done a good job there

I have my tools in their own spongey space which I had hoped would help. There are a few more now and various knives to look after.

The other option is to sneak them all in at night and hide them throughout the house until Spring
