Gail from Denmark writes

How long after spraying grass, does it take to kill off the grubs from the Japanese Beetle?

Also, is it ok if it rains 1 hour after application?


Sevin Concentrate is not for use on turf nor labeled for grubs.  It is only for use on ornamentals and listed edibles for adult Japanese beetles. Sevin Granules are labeled for grubs in lawns and would be a better option.  You do want to water in after application.  It can take a few hours for pests to die after contact. You can also find our full line of grub products on our Grub Control Page.
