    I set up a small pool for my children in the summer. Are these safe to put in the pool with them - specifically if they accidentally drink some of the water or get it in their eyes?

  • Asked by Jerry from Grapevine, Tx

    Q
    Can I use BTI Mosquito dunks to control mosquitos in French drains?
    I have a bad mosquito problem which I think is coming from my French drain system underneath my backyard concrete patio. There are 6 inlets, and it really seems that the problem is coming from the inlets. I have sprayed the rest of the areas with backyard control products that is supposed to last for a few months, and also have a mosquito misting system. The only pesky area is righty at our feet and it drives us crazy! I've used a little bleach in the drain inlets because someone told me that would help... Only worked for a few hours. The drains are those black plastic ribbed type and I'm pretty sure they nearly always have a little standing water in them due to the ribs. What's the best solution? Would crushed up BTI donuts work if I poured a few gallons of water after insertion to have it spread out down the pipes?
    A

    BTI Mosquito Dunks will be a great choice to apply in french drains for mosquitos. We recommend using Bifen IT and Pivot 10 on the exterior of the home as well as other non-chemical methods for eradication. I have included some great articles below that you might find extremely helpful!   Mos…

    Q
    How long does it take for BTI Mosquito Dunks to work?
    I see mosquito larvae in my backyard pond (small).
    A

    BTI Mosquito Dunks will start working as soon as you place them in the water areas where mosquito larva can be found. It will slowly start breaking down and creating a layer on the water that should prevent the mosquito larva floating there from becoming adult mosquitoes.

    A

    BTI Mosquito Dunks will not dissolve immediately into water as that is not how they are designed to work. They float on standing water areas to slowly break down over about a 30 day time frame to sterilize the water so no mosquitoes can lay viable eggs in the water. If you wish to toss a dunk into y…
