Lawn Problems
Q.

When should I apply grub-ex treatment?

Zone Northeast | mariac37 added on March 13, 2012 | Answered

Last year, my lawn was infested with grubs. I treated the problem in the spring with a Grub-ex product. Over the summer, the grass did improve somewhat. Now, in March, I see the same pitted holes and brown patches of grass on my lawn. Should I treat the lawn in April with Grub-ex? Can you recommend a product?

You will need to wait until summer for conventional treatment, but organic treatments may be effective sooner. Nematodes or Milky spore may attack the grubs at any stage in their life.
