Bactimos Mosquito Control Dunks — floating BTI briquets, 30-day protection for birdbaths & gutters

Bactimos Mosquito Control Dunks are floating BTI briquets that steadily release a natural larvicide to control mosquito larvae in standing water.

These ready‑to‑use briquets contain Bacillus thuringiensis israelensis (BTI), a biological control agent formulated to target mosquito larvae where they hatch. Each dunk floats on the water surface and disperses active ingredients gradually, making it simple to treat bird baths, gutters, rain barrels, and other stagnant water sources without constant reapplication. Because they act where larvae feed, these briquets reduce the next generation of mosquitoes while minimizing impact on non‑target areas when used according to directions.

How do these briquets work and how long do they last?

The briquet floats and slowly releases BTI into the water where mosquito larvae feed, delivering an effective dose over time rather than a quick spike. Typical longevity depends on water conditions and temperature but one dunk commonly protects small water sources for up to 30 days.

• Slow‑release formulation targets larvae at the water surface and just below.
• Effective in small containers, gutters, ponds edges, and similar habitats.
• Lasts roughly 21–30 days in most residential standing water sites.

Where can I safely use Bactimos Dunks around my home and property?

These briquets are intended for nearly any location with stagnant water where mosquitoes breed. They are ideal for isolated or hard‑to‑reach pockets of water where conventional spraying is impractical or undesired.

• Bird baths, flower pot saucers, and rain barrels.
• Old tires, animal watering troughs, and pond edges.
• Gutters, tree holes, unused pools (particularly above‑ground), and small drainage areas.

Are these safe for pets, wildlife, and beneficial insects?

BTI targets mosquito larvae and is widely used as a biological larvicide when applied according to label instructions. It has minimal activity on most non‑target organisms, but users should follow the product label to avoid unintended exposure and protect beneficial species.

• Formulated for mosquito larvae; limited effect on fish and other wildlife when used properly.
• Apply only in stagnant water where label allows; do not introduce to drinking water sources.
• Follow disposal and application guidance on the product packaging for safety.

How easy is it to apply and maintain control?

Application is straightforward: drop a dunk into the targeted water and replace according to the product’s active period. This makes it convenient for seasonal upkeep without frequent reapplication or specialized equipment.

• Ready‑to‑use — no measuring, mixing, or special tools needed.
• Low maintenance: inspect water monthly and replace briquet as needed.
• Works well as part of an integrated effort with source reduction and screening.

Who is this for: Bactimos Mosquito Control Dunks suit homeowners, property managers, and caretakers who need an easy, targeted way to reduce mosquito breeding in small, stagnant water sites. They are useful for people maintaining yards, gardens, pools, pet areas, and public spaces who prefer a biological option that fits into routine property maintenance. Always read and follow label instructions before use.
