Kills Mosquito Larvae Before
They Can Become Biting Adults
MOSQUITO DUNKS® are formulated to release
effective levels of Bti for a period of 30 days or more under typical
environmental conditions. The floating action of the dunks will ensure
that active material is released at the surface as well as gradually
settle to the bottom.
These dunks may be used in all types of
containerized mosquito breeding areas. To prevent dunks from being
flushed out of certain treatment sites, they can be anchored using a
string tied through the hole in the center or staked in place.
MOSQUITO DUNKS® can also be applied to dry areas which
are known or suspected to become breeding sites when flooded, such as
abandoned swimming pools, the dunks will float to the surface when
flooding occurs and start releasing the active Bti material. Alternate
wetting and drying will not reduce their effectiveness.
Application Rates
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.
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.
