Snail Invasion in South Florida: Long-Term Management

Snails everywhere—house walls, carport, furniture—in South Florida. The homeowner wants permanent eradication.

Reality Check: "Permanent" Isn't Possible

Snails (and slugs) are a fact of life in humid subtropical climates. Management, not eradication, is the goal.

Two-Pronged Approach

1. Reduce Moisture & Habitat

• Cut back irrigation—snails need moisture.
• Remove hiding spots: boards, pots, dense ground cover, debris.
• Water in morning so surfaces dry by night.

2. Use Iron Phosphate Baits

• Safe for pets, wildlife, and edible gardens.
• Apply in evening when snails are active.
• Reapply after rain and every 2-4 weeks during wet seasons.
• Avoid metaldehyde baits—toxic to dogs, cats, birds.

Long-Term Commitment

Expect to bait several times a year, every year. Contact the UF/IFAS Extension (solutionsforyourlife.ufl.edu) for Florida-specific advice.
