The summer lawn problem

In June and July, many homeowners start noticing sudden patches of torn-up grass. These areas are often mistaken for disease, drought stress, or fertilizer burn, but in many cases the real cause is wildlife activity driven by grubs in the soil.

Skunks, raccoons, and birds actively search lawns during this time because grubs are present in the upper soil profile and are actively feeding on grassroots.

What grubs are doing in June–July

Grubs are the immature stage of beetles such as Japanese beetles and June beetles. By early to mid-summer, newly hatched grubs begin feeding on turf roots.

During this period:

  • Grubs are closer to the soil surface
  • Root feeding begins to increase
  • Turf becomes easier for animals to tear up
  • Populations begin building toward peak damage later in summer

This makes June and July one of the most important windows for grub control applications.

Why animals start digging now

Skunks and raccoons have a strong sense of smell and can detect grub activity underground. Once grubs are present in enough numbers, they become an easy, high-protein food source.

Common signs include:

  • Small patches of rolled or flipped turf
  • Areas of shredded or loosened grass
  • Nighttime digging activity
  • Birds pecking in damaged areas during early morning hours

The animals are not randomly damaging lawns—they are targeting areas where grubs are actively feeding.

Why June–July grub control is important

Applying grub control during June and July helps stop the problem at its source before it escalates.

A properly timed application:

  • Reduces active grub populations before major root damage occurs
  • Removes the food source that attracts skunks and raccoons
  • Helps prevent visible surface disruption in mid to late summer
  • Protects turf health during peak heat stress periods

Once animals begin digging, the lawn is already being physically damaged. Preventative treatment is significantly more effective than repairing damage after the fact.

Why timing matters

Grub control products are most effective when applied while grubs are small and actively feeding. June–July applications target this early stage, helping prevent larger populations from developing later in the season.

Summary

Summer grub activity is one of the leading causes of sudden lawn damage. Skunks and other animals are responding to what is happening below the surface.

By applying grub control in June and July, the food source is eliminated early, turf is protected during peak stress periods, and costly wildlife damage is prevented before it starts.

Healthy lawns start below the surface, before the digging ever begins.
