Grub Worm Control Services in Boerne, TX

What Are Grub Worms and Why Are They a Problem?

Grub worms are the larval stage of various beetle species, including June beetles, Japanese beetles, and chafers. These C-shaped, cream-colored larvae live beneath your lawn's surface, feeding on grass roots throughout their development. A healthy lawn can typically tolerate a few grubs per square foot, but when populations exceed five to ten grubs per square foot, serious damage occurs rapidly. In the Texas Hill Country, grubs are particularly problematic because our climate provides ideal conditions for multiple beetle species to thrive. 

Signs Your Lawn Has a Grub Problem

Visible Brown Patches

Dead or dying grass appears in irregular patches that expand over time. Unlike drought damage or disease, grub-damaged grass doesn't respond to watering and fertilization. The patches may appear in late summer or fall when grubs are actively feeding.

Spongy Turf That Pulls Up Easily

Because grubs destroy root systems, affected grass loses its anchor to the soil. Walk across your lawn—if it feels spongy underfoot, you may have grubs. You should be able to pull back sections of damaged turf like rolling up a carpet, with little to no root structure remaining underneath.

Increased Wildlife Activity

Birds, skunks, raccoons, and armadillos dig up lawns to feed on grubs. If you're seeing more digging activity or wildlife visiting your yard, they may be after the grubs beneath your grass. While these animals are helpful in reducing grub populations, the damage they cause while hunting can be extensive.

Visible Grubs in Soil

During a simple inspection, pull back a small section of affected turf and examine the soil. Grubs are most visible in the top three inches of soil. If you find more than five grubs in a one-square-foot section, treatment is recommended.

Understanding Treatment Timing

Different beetle species have different life cycles, but most follow a similar pattern in our area. Adult beetles emerge in late spring and early summer, laying eggs in lawns. These eggs hatch into grubs that feed on roots from late summer through fall. Grubs overwinter deeper in the soil, then move back toward the surface in spring for a final feeding period before pupating into adult beetles.

The most effective treatment windows are:

• Late Summer/Early Fall – Target young, actively feeding grubs (most effective)
• Late Spring – Catch grubs during their spring feeding period (effective but narrower window)
• Winter Treatments – Special formulations can work during mild Texas winters (see our coupons)
