Exterminator

The Exterminator is a Service NPC in The Sims 2. If your lot is filthy, or has been visited by an evil witches, and you see cockroaches crawling around, call the exterminator and he will rid the lot of them for you. In The Sims, the Maid, Servo, and Bonehilda will do this as part of their duties, as there is no exterminator NPC in Sims 1. In both games, Sims can perform the action "Spray", which causes your Sim to use bug spray to kill the roaches. If you don't call the exterminator and try to step on the bugs, you will get sick.

He (the Exterminator is usually a man) wears a yellow suit with orange details and a hat. He also carries a tub of bug spray on his back which connects to a hose in his hand. If you have a butler, he will call the exterminator but can't actually spray the roaches himself.
