  • Asked by Tanya from Owasso, Ok
    05/16/2017
    Q
    Which is more effective for mosquito control - BTI Mosquito Dunks or Altosid?
    We have natural drainage ditches around our house, and several low areas hold water. There's also a more quickly moving creek-like ditch behind our house. Which would be more effective - dunks or granules?
    A

    A granular product like Altosid Pro-G Mosquito Larvacide would have an advantage over the BTI Mosquito Dunks because the Altosid granules would disperse over a farther range than a mosquito dunk would cover.

  • Asked by Jessica from Uniontown, Ohio
    06/25/2018
    Q
    Can you use water treated with BTI Mosquito Dunks to water your lawn?
    We have alot of gnats in our grass. When our dogs are outside laying down they are covered in them. Trying to find a non-harmful way to get rid of them.
    A

    BTI Mosquito Dunks are only meant to be used in standing water areas like bird baths, ponds, etc. If you wanted to treat your lawn for gnats you would want to use an actual insecticide like Bifen I/T which is a clear drying insecticide that would last on the lawn for at least 30 days to give continuous control over the gnat population and would be completely safe for your pet to lay on once dry. Bifen I/T is used at the rate of 0.5-1 oz per gallon of water and can be sprayed on lawns, bushes, trees, hedges, flowers, etc for gnat/mosquito control.

  • Asked by Arlette from Clayton Nc
    08/20/2014
    Q
    I am having a problem with terminology of the BTI Mosquito Dunks.
    The website refers to Mosquito Dunks. The product is sold in pack of 20. Each briquet will effectively treat up to 100 square feet of surface water. I worked out that a pack holds 20 dunks but what is a briquet? I know what it is in French but I doubt that applies here!
    A
    A briquet is a small brick of compressed coal, sawdust, etc. In this case, it is a small brick of Bacillus thuringiensis subspecies israelensis solids, spores and insecticidal toxins. It is just another name for the individual BTI Mosquito Dunks. Please let us know if you have any additional questions.

  • Asked by Sara from Atlanta

    Q
    Is it possible that deer are eating the BTI Mosquito Dunks?
    I keep putting dunks in my bird baths and they keep disappearing.
    A

    We really couldn’t say what is happening to the dunks honestly.  Per the product manufacturer of the BTI Mosquito Dunks the insecticidal toxins are a by-product of the bacillius thuringiensis in the dunks with is not harmful in any way to non-target animals.  So if they are eating the dunks it should not harm them.

  • Asked by Shelley from San Diego
    07/09/2019
    Q
    Will BTI Mosquito Dunks kill mosquito larvae in my water garden?
    A

    Yes, BTI Mosquito Dunks kills mosquito larvae before they are able to grow into mature, biting adults, eventually controlling the mosquito population.  As the briquets float, BTI (or bacillus thuringiensis israelensis, a natural mosquito-killing biocontrol agent) is slowly released at the water’s surface and gradually settles in the water where it is consumed mosquito larvae.

    Q
    Can you use BTI dunks in a pond used for drinking water?
    I have a customer who has a pond that is used to provide drinking for his home. I'm not sure of what sort of filtration system he has, but I'm wondering if it would be ok to use the BTI dunks to treat the water? He has another pond that doesn't provide drinking water that he uses the methoprene dunks on and I didn't think he should use those for his drinking water pond, but wondered about the use of the BTI dunks?
