## Description

The briquets/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 briquets/dunks will ensure that active material is released at the surface as well as gradually settle to the bottom. These briquets/dunks may be used in all types of mosquito breeding areas. To prevent briquets/dunks from being flushed out of certain treatment sites, they can be anchored using string tied through the hole in the center or staked in place. They can also be used for preflood treatment. If the briquets/dunks are applied to dry areas which are known or suspected to become breeding sites when flooded, such as woodland pools and abandoned swimming pools, the briquets will float to the surface when flooding occurs and start releasing the active Bti material. Alternate wetting and drying will not reduce their effectiveness.

Review: superb product & great price - great product appeared to work straight away. Update:- 3/06/20 just finished this card of dunks, only use on a large Koi pond to maintain, all the aquatic bugs ( mozzies, black, fruit flies etc.... ) Again only use in the spring/summer here in the UK, very temperature dependant, but they certainly break up the life cycles, I bought an expensive U/V, professional light tube zapper, before finding these! The zapper has not been used for years? The downside is that the product only appears to be available in USA? So the price with shipping, has more than doubled? Why? This makes them prohibitive now. Looks like the Zapper will make a comeback!!!

## Questions & Answers

**Q: What area/volume of water does one Dunk treat?**
A: APPLICATION RATES
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. 

SAFE FOR USE IN FISH HABITATS
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. 

Surface Area of standing water        1 to 5 square ft.       5 to 25  square ft.     25 to 100 square ft.      Above 100 Square ft.
Use quantity                        ¼ Dunk             ½ Dunk           1 Dunk          1 Dunk per 100 sq. ft.

**Q: Will they harm my carp and Goldfish**
A: No. I have personally microchipped hundreds of carp and know of others who have chipped thousands and I have no knowledge of any carp having any bad reactions either during chipping or since.

**Q: If I buy the large pack and have some left over, will they be effective say 9 months later?**
A: I am just about to find out....  :)  Will update in a few weeks when it's clear what is or is not happening. They were certainly effective all last summer.

**Q: Is this safe to put in the pond with stergions and gold fush**
A: I put one in my pond which has goldfish in it and they are fine.

*by P***B on 5 August 2015*

Mosquito dunks worked brilliantly. My small still (no flow or fountain) wildlife pond was full of mosquito lava which cleared in about 2 days. I use half a dunk once a month and so far it has remained clear of them.
