Question: My lawn is overrun by grubs, how do I get rid of them?

Answer: First of all, a little bit about these pesky grubs. Grubs are the larvae of the Japanese beetle. They lay eggs from early to middle of summer. As these eggs develop into grub worms, they begin to feed on grass roots until the fall. So, the best times to treat for grubs are in the Spring or in the Fall using products like Milky Spore, Merit, Dylox or Sevin.

To prevent future infestation of grubs, take these preventative measures:

1 – The Japanese beetle does not like laying eggs on long grass, so don’t give your lawn a buzz cut. Cutting it at least 2 inches long should help keep the grubs away. They don’t like thick grass either, so over-seeding your lawn is a good idea also.

2 – Water your lawn less frequently, but deeply each time rather than watering frequently. Frequent watering not only promotes shallow roots, but provides a moist environment which grubs need to hatch. (See also: Top 3 Mistakes You Must Avoid When Watering Your Lawn.)
