Question
I live in Mentor, Ohio.  We were planting some petunias and noticed several grubs in the soil. Are they going to ruin my flowers?  What can be done about them?  Last year the flowers didn't do well there and I suspect the grubs ate the roots.    I know grub-x will take care of lawns but What about flowers?

Answer
Ann, Grub-ex is by far the best product on the market for an immediate resolution.  The problem with this product, as well as diazinon, is that they are only effective the year they are applied.  The problem will most likely reoccur next year, making this a very expensive proposition.

The best natural control for grubs is Milky Spore.  This is an organic product which kills only the grubs, while sparing earthworms.  Another benefit to milky spore is that it lasts for up to 15 years without needing to be reapplied.  The only downside is that it can be costly.  But given the fact you only need to apply it once every 15-20 years, it is the least expensive alternative over the long term.

Attached is a website which will give you additional information as well as a source to purchase the product.

Good luck, and write again if I can ever be of assistance.
