Grubs Destroying Lawn Repeatedly? Try Milky Spore

A homeowner lost their septic field lawn to grubs twice. GrubEx worked for one year, then failed. Crabgrass took over after reseeding. Pre-emergent would block new grass seed. Milky spore purchased but not used.

Why GrubEx Isn't Enough

GrubEx (chlorantraniliprole) is effective but must be reapplied annually. For large areas, cost adds up.

Milky Spore: The Long-Term Solution

• Organic, grub-specific (Paenibacillus popilliae bacterium).
• Kills only Japanese beetle grubs; harmless to earthworms, pets, humans.
• Lasts 10-15+ years once established in soil.
• Apply once, water in. Grubs ingest spores, die, release billions more spores.
• Higher upfront cost, but cheapest over time.

For crabgrass: Use a pre-emergent after new grass is established (mowed 3-4 times). Or spot-treat crabgrass with post-emergent herbicide (quinclorac) safe for new grass.

Apply milky spore now. It's the only treatment that builds lasting soil immunity.
