People I know have used them for protection against mosquitoes. I am not sure if it actually works, since I have not been able to garden for several years, however those who have told me have been in their garden around sunset when the mosquitoes are most active and I have yet so see any bite marks on them afterward.

because they smell.
they keep everyone away from the garden so that no one can step in it and destroy the other plants and flowers without coming out and smelling like marigold.
kind of like a security alarm tag.
not really, but it does sound reasonable, no?
