All Climate Zones
Compare termite risk across different climate zones.
High seasonal risk, warm winters, humid summers. Year-round vigilance needed.
TL;DR: Subtropical zones (Gulf Coast, Southern California, South Texas) face high seasonal termite risk. Warm winters eliminate dormancy; humid summers peak activity. Annual inspections before spring season recommended. — How inspections work or call (833) 404-3632.
Subtropical regions sit between tropical and temperate zones, creating unique termite pressures. Warm winters prevent the dormancy that slows temperate-zone activity, while humid summers create ideal breeding conditions:
Build mud tubes from soil to wood. Create large colonies. Cause extensive damage. Most common species in subtropical regions. Active year-round but peak in spring/summer.
Live inside wood without soil contact. Produce pellet-like frass. Smaller colonies but harder to detect. More common in Southern California. Active year-round.
Prefer high-moisture wood. Found in coastal areas and areas with water intrusion. Less common than subterranean but indicate moisture problems.
High-risk areas: Crawl spaces (warm, moist), attics, bathrooms and kitchens (moisture), exterior wood (foundations, decks, siding), areas near downspouts or poor drainage, wood-to-soil contact.
Peak season: March–August, especially April–June. Winter (December–February) sees reduced but ongoing activity. Spring swarmers common after warm, humid weather.
Repeated signs: If mud tubes, frass, or discarded wings reappear after cleanup, active infestation likely. One-time sightings may be swarmers, but recurrence indicates established colony.
Multiple locations: Signs in different areas (foundation AND attic, or multiple walls) suggest larger infestation. Immediate professional inspection warranted.
Subtropical zones have distinct seasonal peaks unlike tropical zones. Activity fluctuates predictably:
Reduced activity but not dormant. Termites still feeding in protected areas. Good window for preventive treatments and inspections.
Activity ramps up. Swarmers emerge. Mud tubes become visible. Peak inspection season. Schedule professional checks now.
Highest activity. Warm, humid conditions ideal for feeding and reproduction. Multiple swarms possible. Watch closely for new signs.
Activity remains high but begins declining. Preparation for winter. Good time for follow-up inspections if spring activity detected.
Frass: Pellet-like, uniform size, piles near small holes, tan or brown. Sawdust: Irregular shavings, usually from carpentry, no organized piles.
Mud tubes: Raised, earthy, crumble when broken, often rebuilt. Cracks: Part of the material, don't crumble, not rebuilt.
Termites: Straight antennae, thick waist, equal-length wings, shed wings in piles. Ants: Elbowed antennae, pinched waist, unequal wings.
Termite swarmers: Appear in spring/early summer, soft bodies, equal wings. Carpenter ants: Larger, darker, unequal wings, appear year-round.
Subtropical conditions demand seasonal awareness:
Fix leaks promptly. Ensure proper drainage. Use dehumidifiers in crawl spaces. Ventilate attics. Redirect downspouts away from foundation.
Keep mulch 12+ inches from foundation. Trim vegetation touching roof/siding. Store firewood away from house. Use treated wood for new construction.
Schedule professional inspection before spring (February–March). After heavy rains, inspect within 2 weeks. Monitor for swarmers in spring/summer.
Consider preventive treatments before peak season. Liquid barriers or bait systems recommended by professionals in high-risk areas.
In subtropical zones, professional help is essential. Call immediately if you notice:
