Can I use grubbex on a new lawn?

Answer 1

How new is the lawn? Sometimes you can put down insecticides before you put down a new lawn, especially if you know you have an insect problem.

The trick with grubs is you have to get the material down before the larvae hatch, which us usually in the summer, but depends on where you live. The product in GrubEx is a preventative control ,which means it will kill the larvae provided you put it down at the right time.

If you are trying to kill grubs, I would water the product in, so it can get down to the grubs, but follow what it says on the label. I did not see any restrictions for the use of a similar product on new lawns (both GrubEx and the Bayer Advanced Products are imidacloprid which is the active ingredient), but still follow the label for the product you have. Based on that, I really do not see any reason why you couldn't use the product on a new lawn.

Answer 2

Don't bother with grubex. It works only for a season. Treat the lawn with Milky Spore disease and after a couple of years when it is fully established, you will never have another grub in your lawn.

GrubEx works in Summer but not in Fall or Spring. For those times, I would recommend nematodes.

Here's a site describing GrubEx:
