How do you get rid of a nettle sting?

Mulching, pre-emergent and post-emergent broadleaf weed killers, removal of rhizomes and rootstock, and solarization are ways to get rid of nettles. The perennial weeds in question belong to the Solanaceae and Urticaceae families. They spread by rhizomes underground and by seeds above-ground in compacted soils as well as in grounds benefiting from full sun, good drainage, and sufficient nutrients.
