    Q
    Can I put the BTI Mosquito Dunks under my deck?
    A

    BTI Mosquito Dunks need to be placed in standing water to be effective. If you need to treat the ground where water occasionally collects in pools or puddles, then we would recommend using Altosid Pro-G instead.

    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.

    Q
    I have a pool set up for my dogs is it safe for them to swim in the pool with BTI Mosquito Dunks?
    A

    You can use the BTI Mosquito Dunks directly in wading pools and they will not harm your dogs. These dunks will float on top of the water for several weeks so we would suggest that you take the dunks out of the pool while the dogs are in the water so they will not play with them or try to eat them.
