Jarvis Stanley was a man that attacked people in Farmington with insecticide.
Jarvis Stanley went to Nico's hot dog stand to buy something. When Udel, who was in front of him in the line, took too long to order, Jarvis told him that he "bugged" him and sprayed him with insecticide in the face. He then fled the scene. Jarvis had also attacked Polly the same way three days before.
After Officer Danny Sofer checked on nearby hardware stores where someone could buy insecticide, she traced it to Jarvis. She and Officer Julien Lowe went to his house and arrested him. When he alleged that it was just insecticide, Sofer told him that it was poison.
