Pest Control-Mosquito Dunks - Summit Biological Larvicide Rings | Safe Water Pest Control for Rain Barrels & Ponds

Stopping a massive swarm of biting pests requires treating the exact source where they aggressively breed and multiply. These Summit mosquito dunks act as a highly effective, completely biological larvicide, actively destroying the next generation of flying biters before they ever have a chance to hatch. You can effortlessly protect your outdoor living spaces and enjoy your garden all summer long without constantly swatting your arms.

Formulated with BTI, a naturally occurring soil bacterium, these solid rings float on the surface of any standing water and slowly dissolve over thirty days. When you place these mosquito dunks into a stagnant puddle, the active bacteria are eagerly consumed by the developing mosquito larvae, which rapidly shuts down their digestive systems and kills them within hours. Because this highly targeted biological agent only affects specific flying insect larvae, it is absolutely safe for fish, frogs, visiting birds, and your roaming pets. You can even use the treated water safely on your outdoor potting mix without any fear of chemical contamination.

Toss one entire ring into your large decorative koi ponds, deep rain barrels, or neglected birdbaths at the very beginning of the warm spring season. If you have smaller water features or damp, marshy areas acting as a heavy soil conditioner, simply break the ring into smaller pieces for perfectly scaled coverage. These authentic Summit mosquito dunks provide dedicated homeowners with a month-long, highly reliable shield against dangerous, disease-carrying garden pests.

Store in a cool, dry place away from direct sunlight and moisture. Reseal packaging tightly after use to maintain product quality and effectiveness.
