Termite Treatment Options by Climate Zone

January 24, 2026 · Regional Pest Guide Team · termites treatment

Not all termite treatments work equally well in every climate. The best approach depends on your region, the termite species you’re dealing with, and the construction of your home.

Key Strategies

  • Liquid soil treatments (termiticides) — the traditional approach. A chemical barrier is applied around and under the foundation. Most effective for subterranean termites. Works in all climates
  • Bait monitoring systems — stations placed around the perimeter are checked regularly. When termites are detected, bait is introduced. Slower but less disruptive than liquid treatment
  • Fumigation (tenting) — primarily for drywood termites in Southern California, Florida, and Hawaii. The entire structure is sealed and treated with gas. Expensive but comprehensive
  • Heat treatment — raising the temperature of infested areas above 120°F kills termites at all life stages. Non-chemical option growing in popularity, especially on the West Coast

Additional Considerations

  • Borate wood treatments — applied directly to wood during construction or renovation. Prevents future infestation. Most practical during building or remodeling
  • In the humid Southeast: liquid barriers combined with monitoring stations provide the most reliable protection against both subterranean and Formosan termites
  • In dry climates (Southwest, Mountain West): termite pressure is lower. Bait systems or spot treatments may be sufficient
  • In Pacific regions: combination treatments addressing both subterranean and dampwood species may be needed

Taking Action

The key themes here are treatment options climate comparison. Start with prevention, monitor for early signs of problems, and escalate to targeted treatments only when needed. Most pest issues are far easier to prevent than to resolve after they’re established.
