Urtica

Urtica (Nettle)

Where found: Urtica has a cosmopolitan though mainly temperate distribution. The most prominent member of the genus is the stinging nettle Urtica dioica, native to Europe, north Africa, Asia, and North America.

Description: This species have spiny hairs, or stinging trichomes, whose tips come off when touched, transforming the hair into a needle that will inject a cocktail of poisons: acetylcholine, histamine, 5-HT and possibly formic acid. This mix of poisons cause a sting or paresthesia from which the species derives its common name, as well as the colloquial name "7 minute itch".

Control: Nettles should be trimmed to the ground and then sprayed with glyphosate. If the re-emerge, they should quickly be hit with glyphosate a second time.
