Question ziplock, silica gel, humidity

Currently I keep some electronic devices (snes cartridges) inside boxes and in a semi-open anti-static bag but I'm not using any moisture protection silica gel, I bought a ziplock bag and silica gel and I received them today, my doubt is if Do you need to use these devices before placing them in the ziplock bag with silica gel sache to expel moisture from the board?

So you're going to extend the life of SNES cartridges by putting them in plastic bags with silica gel? Cartridges that were made 25 to 30-years ago and stored in peoples basements, under their beds, in attics or garages until you acquired them?

I don't think it matters much exactly how you put the cartridge into the plastic bags.
