Homes with standing water sources (ponds, bird baths, planters, rain barrels) where a low-toxicity, ongoing larval control is desired.
Great Value
Approximately one month per application in still water; longer in favorable conditions.
Key Buying Points
BTI larvicide mechanism targets mosquito larvae with minimal non-target impact, protecting ponds and water features.
Each dunk treats up to 100 square feet of standing water for 30+ days, reducing maintenance and reapplication.
Non-toxic to wildlife, pets, fish and humans, making it suitable for ponds, water gardens, and other outdoor water features.
Easy application—simply drop the puck into standing water; no mixing or spraying required.
Versatile for multiple standing-water environments (ponds, rain barrels, planters, water gardens).
Bulk 20-pack delivers cost-effective ongoing control for larger properties or multi-site use.
Offers preemptive larval control to reduce adult mosquitoes before biting begins.
The Catch
Larval-only control: does not kill adult mosquitoes.
Effectiveness depends on water remaining still; moving or highly aerated water can reduce performance.
Higher price point per treatment compared with some DIY alternatives.
Not a stand-alone solution; should be part of an integrated pest management plan.
Requires reapplication when water is replenished or after seasonal changes.
