WHEN DEALING WITH GRUBS, you should first determine if they are really causing a problem. Pull up a 1 ft. square section of sod and turn over the soil below. If you see more than 4 or 5 grubs, then you may have a problem; any less than that is not enough to worry about.

If you're in the trouble range you should do a few things:

1. Try using a product called Scanmask or Margosan-O. Margosan- O is an organic grubicide made from Neem oil.

   Scanmask is a solution of beneficial nematodes which search out and kill grubs within a week at the very most.

   Please keep in mind that both of these are only solutions for dire situations. If the grubs are not causing any immediate damage (brown patches, loose sod, etc.), don't use these methods. Although they are better than chemicals, they can still upset the natural balance of the soil to some degree.

   Option 2 below might be a better alternative if there is no immediate damage but you'd like to rid yourself of the grubs so as to be sure there isn't any future damage.

2. Another available long-term option is to apply milky-spore disease to your lawn. This is completely safe for humans and pets, but fatal to grubs. Treatment can last up to 10 years.

3. To stop grubs from popping up next year, get the beetles this year. You might try walking the yard in the early morning and collecting as many beetles as you can.

4. Plant trees and shrubs to create a natural habitat for grub predators such as birds. This will help eliminate the need for steps one and two and three in the future.
