Q: How many Rat Zappers do I need?

A: For residential users, we recommend 1 Rat Zapper for every 1000 square feet of living space. For commercial users (or very large buildings) with more than 50,000 sq. ft., we recommend a strategic approach. Get enough Rat Zappers to cover a "section" between 10,000 and 50,000 sq. ft. in size. Spread those Rat Zappers out over the whole complex and monitor the activity. Then, move inactive Rat Zappers to the "hot spots" as necessary.
