So far, my favorite new insight from the articles:
MANY companies claim to have built a better mousetrap. Rentokil has actually done so. The British building-services firm added a small sensor and a wireless module to its traps so that they notify the building staff when a rodent is caught. This is a big improvement on traps that need to be regularly inspected. A large building might contain hundreds of them, and a few are bound to be forgotten.
