Billbug Control & Treatment
Billbugs are one of the most damaging lawn pests in Idaho. These small weevils and their larvae feed on grass stems, causing brown patches that can quickly spread across your lawn if left untreated.
Identifying Billbug Damage
Billbug damage is often confused with drought stress or other lawn problems. Here’s how to identify it:
Visual Signs
- Brown patches that appear in late spring to mid-summer
- Damage often starts in sunny, stressed areas
- Grass breaks easily at the crown
- Sawdust-like frass (excrement) at the base of plants
The Tug Test
Pull on grass in the affected area. If it breaks at the crown but the roots stay attached, you likely have billbugs. (Grub damage, by contrast, causes grass to pull up like carpet because the roots are eaten.)
Finding Billbugs
At the base of damaged grass, you may find:
- Small white larvae with brown heads (no legs)
- Adult billbugs: small black or brown beetles with distinctive snouts
Why Timing Matters
Billbug control is all about timing. The larvae cause the most damage, but they’re protected inside grass stems where they’re difficult to reach. Treatment must target billbugs at specific points in their lifecycle:
- Preventive treatment (late spring) is most effective
- Curative treatment (once damage is visible) is more challenging
- Professional timing based on local conditions is critical
