    I have trouble killing large lawn grubs. Dylox doesn't work on them. They are easy to kill when they are small but what can be done to kill them now that they are big.
    Please help!!

    Large is about 1 inch long. I tryed Dylox granules at 25gr / square meter. (Excuse my metrics) but that is the advised rate.
    I have digital photoes of them. How do I post them?

    It is going to take heavier dosage, and longer to kill adults than small ones.

    I dont know turf where you are but maybe this will help.

    Here in Mass (USA) grubs mostly feed in the late summer- fall months, thats when there young and small, they do much more damage at this stage than any other. I dont know of any species that dylox dosnt work well on.

    In spring when they move up to emerge there big, and usually dont feed, controls at this time is usually not needed because there not feeding.

    Spring and early summer we apply merit to prevent the grubs from feeding come fall, and dylox in fall when they are there feeding.

    Some material in the past that worked, maybe you can get some over there.

    Oftanal, triumph, sevin, or Mach 2

    These Ive used in the past with OK results, but by far merit seems to be the best.

    Dylox requires at least a 1/2 inch of water to work its way through the thatch. If it's getting that you may need to up your rate a bit. I have never used a more effective product for active grubs other than possibly Diazinon, which I don't think you can buy any longer.

    Dylox also has a shelf life of about 12 months after which time it degrades pretty quickly. Some bags are date coded.

    If the material is over a year old, I'd be concerned.

    actually dylox does work on grubs but you have to do like 3 apps within a 2 week time period to get results, this is probably not recommended but it is the only way I have found to get rid of the nasty little things. Billbugs too.

    Is that consistent with the label? If not, its against the law.
    You aren't giving the material time to even work. The grubs will still be present and alive but not feeding. Look for them to start turning black.

    Also, do you charge your customer for 3-apps in 2 weeks? How much do you charge them?
