Soap will not kill the grubs reccomend a Granular Insecticide and water it in with 1 inch of water and reapply in 7-10 days. Diazonon is good to use and apply as directed.

Hi,

I just ploughed my lawn this weekend with a tiller.
I saw tons of white grubs.
The city of Ottawa says that I can use soapy water to kill them.
But what kind of soap (laundry detergent, hand soap, etc..)
what concentration ?
Can I spread laundry detergent over the earth and water it ?
how often ?
for how long ?
how many time ?

Please advice,
Thanks,
Bruno.
