When I was director of Outreach I had a group that would arrange visitations to nursing homes. We would make some little care packages and include tracts in them. Covid wouldn't let us do that now, sad
Tracts work because God's Word works, whether it enters the ear-gate (oral preaching) or the eye-gate (reading).
Isaiah 55:11 (KJV) So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
