Exterminator

The Exterminator is a Service NPC in The Sims 2. If your lot is filthy, or has been visited by evil witches, and you see cockroaches crawling around, call the exterminator and they 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 most likely will get sick.

The Exterminaor wears a yellow suit with orange details and a hat. They also carry a tub of bug spray on their back which connects to a hose in their hand. If you have a butler, he will call the exterminator but can't actually spray the roaches himself.
