Gardener's Supply Company – Summit Chemical Co. Mosquito Dunks Set of 20

Protect Standing Water with Natural Larva Control

Standing water around your home can become a hotspot for mosquitoes. The Summit Chemical Co. Mosquito Dunks from Gardener's Supply Company offer a natural approach to curb larvae in ponds, birdbaths, rain barrels, and water features.

How it works

Each Dunks ring contains Bt israelensis, a naturally occurring bacterium that targets mosquito larvae when released into water. The rings are designed to float and slowly release their active ingredient over about 30 days, providing a steady window of protection.

• Contains Bt israelensis for natural larvae control
• Slow-release, floating ring ensures continuous activity
• Each ring covers up to 100 square feet of water surface

What’s in the set

The package includes 20 Dunks rings, ready to place atop your water surfaces. The set is ideal for larger ponds, multiple water features, or seasonal mosquito management around a yard.

• Set of 20 rings for broader coverage
• Effective for ponds, water gardens, birdbaths, and rain barrels
• Sold on Amazon

Practical uses and tips

Place rings on still water where mosquitoes commonly breed. For best results, distribute evenly across the water surface and refresh after the 30-day window to maintain ongoing protection.

Real-life scenarios you might consider:

• Preserve the serenity of a backyard pond by reducing larvae before adults emerge
• Protect a birdbath used by visiting wildlife without harsh chemicals
• Keep rain barrel interiors free from early-stage larvae while collecting water

Why choose these Dunks

• Natural, bacteria-based approach rather than synthetic repellents
• Low-maintenance once placed, with a predictable 30-day activity window
• Conveniently sold as a 20-ring set to cover multiple water features

Note: While these rings are designed for standing water, always follow product guidelines and local regulations for water features and wildlife considerations.
