| Active Ingredient |
|
Bacillus thuringiensis subspecies israelensis solids, spores and insecticidal toxins 10.31% |
| Target Pest: |
|
Mosquito Larvae |
| Pet Safe: |
|
Yes, when used as directed |
| Usage Sites: |
|
Outdoor Use around the Household to kill Mosquito Larvae: MOSQUITO DUNKS can be broken into portions for use in many outdoor applications near the household, such as containerized standing water in bird baths, old automobile tires, rain barrels, abandoned or unused swimming pools (particularly above ground types), tree holes, roof gutters for collecting rainwater, flower pots, animal watering troughs, or water gardens. MOSQUITO DUNKS can be broken and used as shown in the following table, the amount dependent upon the surface area of the water in the treatment site. |
| Application: |
|
Mosquito Larvae:
Flooded larvae breeding sites:
Use one (1) MOSQUITO DUNK for up to 100 sq. ft. of surface area of containerized standing water, regardless of depth. In highly polluted water with a high organic content, the application rate may have to be increased to as much as four (4) times the normal dosage based upon evaluation by the user. When larval populations are high, aquatic vegetation dense, or the water highly polluted at the time of dunks use, pre-treatment with SUMMIT MOSQUITO BITS is recommended. Dunks will then suppress larval development for up to 30 days or more. Some larvae which hatch after dunk application may partially develop before dying. Allow a minimum of 48 hours for their control.
Pre-Flood treatment:
Apply one (1) MOSQUITO DUNK to each 100 sq. ft. of containerized surface which is known or suspected breeding site when flooded.
Evaporative Coolers:
Apply one (1) MOSQUITO DUNK to each 100 sq. ft. of Cooler box or for smaller Coolers refer to the table below for applications rate.

HOW MOSQUITO DUNKS WORK :
- Mosquito Dunks can be used in all types of standing water sites where mosquito larvae grow before becoming adults.
- Alternate wetting and drying will not reduce their effectiveness.
- To prevent dunks from being washed away, anchor them using a string tied through the center hole, or they can be staked in place.
- Mosquito dunks contain no poisonous chemicals and are harmless to other living things.
- Each Dunk of Bti treats 100 sq.ft of water surface regardless of depth.
- Mosquito larvae will feed on them and will be killed continuously.
- You will then be rid of biting adult mosquitoes for the entire season.
- Mosquito dunks, which dry out will start working again when they become wet.
- Unused dunks will remain active indefinitely.
- The floating action of the briquets will ensure that active material is released at the surface as well as gradually settle to the bottom.
- The floating Briquet formulation releases effective levels of B.t.i at the waters surface for a period of 30 days or more. Summit B.t.i. Briquets remain in the water column where mosquito larvae feed, to give you continuous kill.
- Summit B.t.i. Briquets release a constant, low dose of B.t.i, so early instars may survive temporarily. However, continuous ingestion of the active ingredient produces a chronic infection which kills the larvae. So you will not observe pupae, and the adult mosquitoes will not emerge.
- Summit B.t.i. Briquets can be used in both permanent and temporary mosquito breeding habitats. Alternate wetting and drying will not reduce their effectiveness. Summit B.t.i. Briquets can be applied as either a pre or post hatch treatment
- Dunks also can be used as a pre-flood treatement in areas expected to become breeding sources.
