Cynthia from Mandeville, La writes

Will an herbicide like Round-Up have any effect on the bacteria in the BTI Mosquito dunks?

Herbicide and Dunks

Answer:

Herbicides such as should not effect the BTI Mosquito Dunks as long as it is used as directed.  We wouldn't recommend spraying the dunks directly though just to be on the safe side but if applied to a body of water that is also treated with an aquatic herbicide, the dunks would not be effected.
