Wow, what a mess !  Everyone is horrified and wondering what has happened to their lawns . It is actually a combination of mostly night-visiting raccoons, skunks and daytime attacks by CROWS destroying your lawn.
       As you probably know, they are looking for the grubs of the chafer beetle. It is amazing how quickly entire neighbourhoods have been vandalized by these clever-but-unaesthetic vandals !   There is not much you can do.
   In late July/August, there is a nematode solution for sale at nurseries that costs about $80.00 . You mix-up a solution of this eco-friendly chafer beetle grub killer and water it in well.  But, it does nothing to the adult beetles, or the ones in your neighbours lawn.
   The theory is that chafer beetles lay their spawn in crummy/distressed lawns more than in lovely, moist, perfect lawns.  I think this is true.  I haven’t noticed the mess on healthy, very well-cared for lawns. I hope it is not on golf courses, even though I don’t golf.  There is a lot to read online about this and I won’t go into it here.
    We  have no solution to this new problem, and don’t offer anything product-wise that could help.  My suggestion is to wait til the destruction stops (nothing left to eat), then rake up the mess. Spread an even layer of nice topsoil, rake it smooth, and reseed.  Either commit to putting more effort into your new lawn, or think about using a groundcover other than grass…..
