Some think that the 10 days of an odor followed with the chance of a week of flies is more than a minor inconvenience...others may think that of breaking a thumb or finger while messing with a rat trap...even more may think paying a carpenter to come in to patch the ceiling where they put a foot through it while placing out the traps becomes more than a minor inconvenience. And then there is no assurance that the rodent won't kill itself by biting into electrical wiring killing itself anyway or actually starting a fire during the time that setting and checking traps may take.
