first off i am new here so hi to all.

I have a question that i hope some of you might be able to help with,
over the past few days, it looks like ravens, have been attacking my
lawn leaving hugh patches of grass torn up and scatered all over the
place. I believe this is because they are after grubs of some sort.

My question is does anyone know of a way to prevent this happening,

Having animals tear up turf is indeed a classic sign of grubs. If you
want to kill the grubs now, per Steveo's advice, Dylox is the
recommended agent. Next year, apply one of the season long grub
controls. Or if you want to go the organic route, you can try
nematodes, though I think they take a couple seasons to be effective.


and
what would be the best course of action to replace the bare patches,
reseed or place turf in the holes as some are at least 90 sqr cm.

Impossible to answer without knowing climate where you're located or
how many of these spots you have covering what size area, etc.
Guessing and it sounds like you're in the UK, so you probably can
still seed. Normally, I'd use a slice seeder for any larger work,
but if the turf has limited roots, that would probably do more damage
to the grass that's left, so I'd probably do it by hand.




hi to all again and hope to hear from you
