The product label for BTI Mosquito Dunks states, "Use one (1) MOSQUITO DUNK for up to 100 square feet of water surface, regardless of depth. They can be used whole or broken into portions and applied to containerized standing water found near the home..."
Please refer to the table on the product label for how many dunks to use in waters below 100 square feet of water surface.
