Other things noted from this book:

The book identifies garlic-based oil as effective in killing mosquito
larva in ponds (as does derris root and tuba).

"The leaves of molasses grass and sassafras are mosquito repellents."
"American pennyroyal (Hedeoma pulegioides) (aka squaw mint) not
to be confused with European pennyroyal (Mentha pulegium) is a
natural insect repellent. A handful rubbed on the skin emits a pleasant
odor and repels mosquitoes and gnats."

There's mention of Shepherd's Purse (Capsella Bursa-pastoris) seed
as well. There seems to be quite a few uses for this plant, whereby it
takes excess salts out of the environment and returns it to a form use-
ful to other plants.
