Each box contains 12 pouches. Place one pouch per spot, roughly every 8 to 10 feet along walls, entry points and the routes rodents travel. A small room or RV needs a few, a full home around 8 to 12, and a larger home with a garage or outbuildings more.
So one box (12 pouches) covers a typical home, 3 boxes (36 pouches) suit a larger property with outbuildings and leave spares on hand, and 5 boxes (60 pouches) are a strong supply for big properties, several buildings, or keeping many spots treated. Since each pouch stays active for 60 to 90 days, buying more also keeps you stocked for the next replacement.
