Know before you buy
Mosquito Dunks contain BTI, a naturally occurring bacterium that specifically targets mosquito larvae. When the larvae ingest the bacteria, it disrupts their digestive system, effectively eliminating them before they can mature into biting adults.
Yes, Mosquito Dunks are safe for pets, birds, fish, and other wildlife. The active ingredient, BTI, is highly selective and only affects mosquito larvae, leaving non-target organisms unharmed.
Yes, you can easily break a dunk into smaller pieces to treat smaller volumes of standing water. Even a fraction of a dunk will provide effective control for smaller areas.
Each dunk provides up to 30 days of continuous protection. After a month, you should replace the dunk to ensure ongoing control of mosquito larvae.
No, the dunks are biodegradable and will not alter the water quality or chemistry of your pond or rain barrel. They are designed specifically for use in standing water environments.
The dunk will slowly release the active ingredient over the 30-day period. If a portion remains after a month, it is likely depleted of the active bacteria and should be replaced with a fresh dunk for continued effectiveness.
