How can I kill raccoons?

Raccoons are common throughout North America from southern Canada to Panama. Raccoons are one of the largest animals to have adapted well to human development. Suburban areas, and many large cities, have significant raccoon populations. Raccoons are skilled foragers who can thrive on garbage and pet food. They have been known to take up residence in attics and garages, and even to enter houses through "pet doors" in search of food. When confronted by humans or household animals, raccoons may be aggressive. Raccoons that live in cities, however, and thus in proximity to humans, are usually a little less so. Urban raccoons tend to lose their fear of humans over time (especially in wooded areas of urban centres) but this seems to develop in them more of a sense of "if you don't bother me, I won't bother you." A good example of this can be seen if a glass windowpane ever separates human and city-dwelling raccoon. As often as not, the raccoon's response will be indifference or even curiosity, even while under direct observation.
