MOSQUITO DUNKS--
Bti (Bacillus thuringienis israelensis)
Mosquito Dunk/BT israeliensis Product Label
Mosquito Dunks MSDS
The mosquito eggs are very hardy and manage to live under almost all
conditions.
When the water temperature is right, the eggs hatch and become mosquito
larvae
which swim around eating and growing.
In about a week they become full-grown mosquitoes and fly out of the water
looking for someone to bite.
Mosquito Dunks containing Bt israeliensis float on water and will keep
on working for 30 days or longer and are completely biodegradable.
While floating, they slowly release a natural mosquito-killing biocontrol
agent, Bti (Bacillus thuringienis israelensis) at the waters surface.
This agent gradually settles in the water where it is eaten by mosquito
larvae growing there.
Bti (Bacillus thuringienis israelensis) is a bacterial toxin that infects
and kills mosquito and black fly larvae.
It is safe and environmentally sound because it is highly selective, killing
mosquitoes and black flies.
Bti contains no poisonous chemicals and is completely harmless to other
living things! When Bti is eaten by the mosquito larvae, it damages the
gut cells, eventually entering the body cavity. Once this happens, the
larvae die.

KILLS MOSQUITOES BEFORE THEY BECOME OLD ENOUGH TO BITE:
- Used by professionals for more that a decade, Mosquito Dunks® have
proven their value in destroying Mosquitoes - by killing the larvae
before they mature into biting adult pests.
- Made with natural B. T.I., Mosquito Dunks represent a major breakthrough
for people and the environment when compared with the traditional toxic
chemical approach to mosquito control.
- Once a month float a Dunk in the Water Garden and every place water
accumulates around your home - you'll be rid of mosquitoes for the whole
season.
- Each Dunk will effectively treat up to 100 square feet of surface
water regardless of depth.
- Dunks may be broken to treat small areas.
- Kills mosquitoes for 30 days or longer when placed in standing water
outdoors.
- Can be used in bird baths, rain barrels, old automobile tires, ponds,
ditches, unused swimming pools, tree holes, flower pots, roof gutters
or wherever water accumulates.
For smaller areas (flower pots, bird baths, pet water bowls,) Mosquito
Dunks can easily broken into smaller pieces.
Suggested Amounts to Use:
- 1 to 5 square feet 1/4 Mosquito Dunk
- 5 to 25 square feet 1/2 Mosquito Dunk
- 25 to 100 square feet 1 Mosquito Dunk
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.
