    Just wondering if anyone else has ran into a problem with Talstar One not working on ants. They are mainly Pyramid ants. There are hundreds of mounds on a normal 6,000 foot lawn in many parts of town. Spraying seems to make them worse if anything.
    I had the FMC etomologist/rep come out and look at several properties and he said he has never seen anything like it. They are trying to figure something out but I thought maybe someone here might have the answer. The best guess he had right off is that they are resistant to pyrethoids which takes care of many of the chemicals on the market. What does everyone do for ants in the lawn?

    Thanks,
    dwc

    My Termidor is one year old .
    I heard the label has changed to include ants in the yard .
    I've not seen this , just heard it .

    I know your licensed so I won't go there. However have you ever heard the term "Rotate". Yep time for some carbanilate or organophosphate.

    I am way down south and my problem is fire ants. Talstar smokes them when you soak the mounds. And can I ask...why no bait first? Can they not be baited?

    Here homeowners are told to do the "Texas Two Step" use bait then knock out the mounds in a week. After that, bait regularly....Thanks

    Do a search "Fire Ants" or "Texas Two Step" I think I have posted the Texas Two Step more than once. Yes it is very effective. A couple of years ago I had a big argument with Kirby over Top Choice vs the Texas Two Step.

    Now Talstar is Befenthrin which is a Pyrethroid. Pyrethroids have been known to become in-effective in the past. Rotate and use another Chemical Family for a period of time. Then you can go back to them. However be sure not to go from one Pyrethroid to another or you will still have a problem.

    Talstar can break down if left too long in a tank/can.

    I am new here and trying to learn. I have heard good things about Top Choice and wanted to offer it. Have you tried both? I'd appreciate your opinion....Drew

    Our sandy soil in Florida has no chemical holding power. (CEC) Therefore Top Choice has given very mixed results. Top Choice has the same time frame as Hydramethylnon baits for control But cost about 8 times more.

    For whatever reason, I cannot explain, but Fipronil works great on fire ants. However, it does not work on all ants. I've been treating my own lawn with fipronil for 3.5 years now. One app per year. I've had no fire ants. But I do have another variety of ants on my landscape. My wife calls them sugar ants. Not sure what kind they are, but they're there.
