2-Pack Summit Mosquito Dunks | BTI Mosquito Larvae Control for Standing Water

Meet the 2-Pack Summit Mosquito Dunks

Designed for homeowners who want a straightforward way to address mosquito breeding grounds, Summit Mosquito Dunks use BTI—bacteria toxic only to mosquito larvae—to interrupt the life cycle where standing water collects. Each dunk floats in place, releasing its active ingredient over time, so you don't have to worry about constant reapplication in typical backyard containers.

Why this matters

Using a targeted larval control approach can help reduce the number of biting adults around your outdoor spaces. The formula lasts up to 30 days, delivering steady exposure to larvae in about 100 sq ft of surface water per dunk. The 2-pack gives you flexibility for multiple water features, from birdbaths to clogged gutters, rain barrels, and decorative ponds.

What you get

• Bundle includes 2 Summit Mosquito Dunks
• BTI-based formula targets larvae, not adults
• Floating disks release across a season of use

Usage ideas and real-life scenarios

Plop a dunk into any standing water feature to start a slow, steady release of the active ingredient. In a backyard setting, the two-pack allows you to cover separate containers, increasing your potential reach with minimal effort. In rain barrels, ornamental ponds, or pet-safe water features, the Dunks sit quietly while doing their work.

• Good for small ponds, birdbaths, rain barrels, and other standing-water spots
• Discreet, low-maintenance solution you can place and forget for weeks
• Simple to monitor and replace as needed when the 30-day window ends

Important note

Always follow label directions for placement and replacement intervals. This product is intended for outdoor use in standing water features and is part of a broader approach to mosquito control in residential spaces.
