    This is put perfectly. Going back a few years ago I had breakthrough and suspected this was the case. Since that time I have been applying very late June, early July with no problems. Other than a more plentiful naturally occuring watering-in, there really isn't any reason to apply Merit so early anyway. Apply later and get protection deeper into the season where the problem presents itself anyway! Good stuff.

    Theres a lot of advertising pressure from company's like Scotts that get people in the mood for preventative in late April.

    Pro applicators should know the timing.

    One thing I wondered about this year is in the midwest I am convinced beetles emerged from the soil earlier due to the grubs not being deep in the soil and pupating early from the mildest winter on record.

    IF... this happened, could it have created a prolonged mating (and subsequent egg laying) period?

    Do beetles mate more than once? (sluts!) Lay more than one batch of eggs? (fertile myrtles!) Or are they one and done.

    I don't know.

    I do know grub pressure is heavy this year in my area, and same with sod webworm and chinch bugs and I believe this can be directly attributed to the mild winter we had.

    It set up the perfect storm. Dry warm winter with no insect attrition, grubs close to the surface, no winter snow for moisture into spring, an earlier spring than we have had in 100 years, followed a month later by the worst drought in 100 years.

    I can understand the logic behind waiting a little longer to app the merit, however, if you use allectus as i have for the past few seasons, you will miss the 1st generation of chinch bugs!

    It's one and done and they will go back to the exact spot they were hatched and came from to lay their eggs. However as a few have pointed out, with the drought affecting a big part of the US, all bugs including beetles are acting crazy. We have noticed grubs being attracted to irrigated lawns since all the other areas that are not irrigated are as hard as concrete. Couple that with the extreme heat and the life cycle of many insects is all messed up this year.

    Why is that?

    That is what the bayer entomologist told me anyway. I went to a whole ceu class on it. Maybe he made a D- in "BEETLE 101".

    the few damages i have, are on irrigated lawns. I am afraid of not getting it watered in and do apply sometimes a bit early. If i waited 2 more weeks, none of my grub control would have been watered in except irrigated lawns.

    so, in that case, hmmmmmmmmm.

    also though, i experienced the same as above. more than anything though, the grubs are under threshold enough, but the skunks etc are ripping the lawns up feeding on those near wooded areas and irrigated. they know where to look

    Well I have always noticed they return to the same locations. I have never heard or figured out why.
