I put milky spore on my lawn last year, so I'm anxious to see if it makes any difference this year. I would love to hear from people that have done it also! I put it on my flower beds also. I figured thats probably where the Japanese beetles were laying their eggs.

I've been planting things in my flower beds this week. Every time I did, I end up digging up grubs in the flower beds. That is why I was asking if people put grub control on the flower beds too. Hopefully someone that has had success with this can let us know?

I had a lot of success with milky spore application at my previous home to control japanese beetles. It didnt remove the problem entirely - I could only treat my small suburban lot - but it dropped thenumber of beetles from plague to nuisance.

At our new home I treated with milky spore the first autumn but I think I remember it taking a few years to kick in. Too soon to tell if I get lucky this time.

Edit to add: I treated lawn and garden beds, since both places had grubs.

I've heard before that it doesn't work in the colder zones, so Im not expecting much in my zone 5. I was desperate to try something.
