Part 4: Physical Prevention Strategies That Actually Work

Relying on powders alone won’t stop roaches if the entry points remain completely open:

• Use Drain Covers or Stoppers: Place mesh drain strainers or rubber stoppers over sink openings at night when roaches are most active.
• Seal Pipe Gaps: Inspect under-sink cabinets and use expanding foam or silicone caulk to seal gaps where pipes pass through walls.
• Fix Dripping Faucets: Eliminate standing water sources by repairing leaks; roaches can survive for weeks without food, but only days without moisture.
• Maintain the P-Trap: Keep water in seldom-used sinks—a full water barrier in the P-trap blocks pests from crawling up through sewer pipes.
