Synthetic pesticides are sometimes grouped by their ‘chemical class and structure’, and site of action on the pest. These pesticides include the organophosphates, carbamates, organochlorines, pyrethroids, neonicotinoids, and others. Most of these are nerve poisons that kill bugs and other creepy crawlies.
