These are a biological safe method that kills mosquito larvae in your water garden pool, rain barrels, bird baths, or anywhere water collects for a period of time. It kills the mosquitoes that may transmit West Nile Virus, Encephalitis, Dengue Hemorhagic Fever, and Malaria. There are two forms of this biological mosquito control - Mosquito Dunks^® or Mosquito Bits^®.

Mosquito Dunks^® are round with a hole in the center. Simply float the dunk on the surface of the water. One dunk is effective for 100 sq ft surface for a month. Tricker's has tested for other organisms in the pond and have found that Daphnia is safe.

For longer residual control use Mosquito Dunks^®.

Mosquito Bits^® are granulated and are simply spread over the surface of the water. This will settle in the water and be eaten by mosquito larvae. The Bits^® give a quick kill within 24 hours. Sprinkle one teaspoon per 75 square feet . Apply every 7-14 day intervals.

As the Dunks^® slowly dissolves, it releases a bacterium which is toxic to all species of mosquito larvae. Mosquito Bits^® are a granule that contains the same active ingredient found in the Dunks®, but unlike the Dunks® the Bits^® release the larvicide immediately. The active ingredient in Mosquito Dunks^® is Bacillus thuringiensis subspecies israelensis which is a bacterium that is deadly to mosquito larvae and harmless to other living organisms.

Where should Mosquito Dunks^® be used?Just float a biodegradable Mosquito Dunk^® in water troughs, koi ponds, birdbaths, rain barrels or any place where water collectsand remains for periods of time. When female mosquitoes laytheir eggs in standing water treated with a Mosquito Dunk^®, thelarvae will hatch and begin to eat the B.t.i. The B.t.i. will kill themosquito larvae before they can grow up to become biting anddisease-spreading adults.

William Tricker (1853-1916) started commercial water lily culture in the United States in the late 1800's. He began experimenting in hybridizing water lilies and what helps their growth. The shape, colors and hardiness of his beautiful aquatic plants has withstood the test of time.

In the early 1890's, hybridization of water lilies gave him a reputation as a leader in aquatic plants. He established a water lily nursery and company in both Ohio and Pennsylvania that were passed down to his family until the 1980's when Richard Lee purchased the Ohio company. In 1892, the first William Tricker catalog was mailed to customers across the nation.
