    I realize merit 75wg is labeled only for suppresssion ,which means it not worth a damn for sod web worms . need a couple sugestion to kill of the bugger after they are identified and present .Dont like to use 7 in any form.

    i agree...7 sux
    dylox is pretty good on webworm
    talstar is pretty good also

    but...about seeing holes...have you totally ruled out birds?

    Holes like you describe (bigger by far than a webworm) are usually due to mole crickets hereabouts.
    Either way, Orthene will do the job.

    I like using Talstar, it has a broad label and bifenthrins are very safe. If there are sod webworm actively fedding you should be able to find them. Here I have often noticed that starlings leave pencil sized holes when digging through a lawn for sod webworm.

    I would suggest my tried and tru method for telling if its Sod Webworm or not:
    I get down on my hands and knees and crawl around, poking throught the grass, into the thatch layer, looking for them. Also look for their droppings, or frass. It almost looks like little bits of Penn Mulch. Check aound on the net, I'm sure you'll find some shot of it someplace.

    If they are webworms a soap flush will bring the little buggers out.

    That being said, if they are webworms, make sure you know what stage of the life cycle they are in. Webworms will have 2-3 generations per year and rather then treat at the end of one life cycle hit them at the start of the next for better success.
