Beneficial Nematodes vs. Milky Spore for Texas Grubs & Fire Ants

Texas: Japanese beetle grubs + fire ants. Considering beneficial nematodes (Antidote brand) for grubs/fire ants/fleas + milky spore (slow, long-lasting). Worried nematodes hurt earthworms.

Nematodes Safe for Earthworms

livingwithbugs.com/ent_nems.html confirms: No earthworm harm.

Strategic Advice

• Milky spore: Grub-specific, 10-15 yr residual. Good for Japanese beetles.
• Fire ants: Treat separately with baits + mound treatments (livingwithbugs.com/fire_ant.html). Nematodes give poor fire ant control.
• Combo OK: Nematodes for grubs/fleas + baits for fire ants.

Don't rely on nematodes alone for fire ants.
