After finding ants in her home for the first time ever, a senior woman is happily surprised to see a new-to-the-neighborhood exterminator at her door passing out fliers. He explains that her trouble doesn't mean that she isn't keeping a clean house, but that the ants have found a way in. She hires him on the spot.
When she later comes down to the kitchen to check on his progress, he sprays her with the bug spray - killing her. With her dead on the floor, he calmly calls her husband, informing him that the job is done. She suffered little, and it will look like an accident. They talk of his fee, and the woman's husband mentions that he may have another customer for the exterminator. One problem: The person to be exterminated is a man. The exterminator tells him that's no problem because "a pest is a pest."
