The repellent works better in enclosed areas so I’d recommend placing one pouch per a small room, closet, storage or vehicle. Try to remember where you saw the rodents for the last time and place at least one pouch there. It’s quite efficient to place them near the entry points as you get to cover the space of two rooms with it. Bathrooms are also good strategic points, just be sure the pouches won’t get damaged by humidity there.
