To combat insects such as lice infestation, the Paiute and Shoshone of the Great Basin (the largest area of contiguous endorheic watersheds in North America) for example, washed their hair in a hot infusion made from sweetroot in the early 1800's.

To fight other pests, pre-Columbian peoples built structures with cashew wood, while the Pima sprinkled ashes on their crops to thwart squash bugs. The Pueblo have used ground buffalo gourd to fend off garden pests, and Inca cotton farmers planted lemon verbena and burned it as a pesticide.
