Prevent Freeze Damage to Pest Control Spray Equipment

Winter freeze destroys sprayers—manual and powered. Damage is avoidable but common. PMPs report burst wands, cracked pumps, costly downtime.

Key Principles

• Pressurized equipment freezes worse. Always release pressure after each stop and daily.
• Discuss climate with supplier for appropriate design.
• Never operate frozen equipment—thaw first.

Prevention Strategies (Low to High Risk)

1. Store in heated space: zero risk.
2. Drain system, remove pump/gun/filter, store indoors. Open all valves. Use quick-remove fittings.
3. Run antifreeze through system. Install pre-pump fittings for easy pouring.
4. Heat pump with battery blanket or bulb-in-box (avoid fire hazard). Drain first. For periodic deep freezes.

Winter is slow season. Don’t compound it with preventable equipment failure.
