What are the different pests that can be found in establishment and what are the ways to control or prevent them?

I have asked that this question be transferred to the Pest Control forum.

I am assuming you are asking about commercial establishments. The standard pests in industrial environments are roaches, rodents, and ants. In institutional environments the focus will be more insect related, although some rodent control may be necessary. In retail and office environments, spiders and roaches are primary concerns.

Control and prevention vary with the site and the target pest population. The one thing all control measures require is thourough and frequent inspections to evaluate the effectiveness of current measures and determine if new pests have invaded.
