Subterranean Termite Treatment & Prevention Soil Treatment | Bait Systems | Moisture Control Solutions

Subterranean termites live in soil and build mud tubes to reach wood. Unlike drywood termites (which live entirely in wood), subterranean colonies require ground contact and moisture. Treatment focuses on soil barriers, bait systems, and eliminating moisture sources.

Understanding the Two Types: Drywood vs Subterranean Termites

California has two primary types of termites that damage homes: drywood and subterranean. They behave completely differently, require different treatments, and have different warning signs. Here’s how to tell them apart.
Characteristic
Drywood Termites
Subterranean Termites
Where They Live
Entirely inside wood (No soil contact needed)
In underground colonies (Require soil contact)
Colony Size
Small: 1,000-3,000 termites
Large: 60,000-1,000,000+ termites
Moisture Requirements
Can survive in dry wood (Extract moisture from wood)
Need constant moisture source (Die without it)
Visible Signs
• Pellet-like droppings (frass) • Discarded wings • Tiny holes in wood
• Mud tubes on foundation/walls • Damaged wood near soil • Swarmers in spring
Damage Pattern
Galleries across wood grain (Clean, hollow chambers)
Galleries follow wood grain (Packed with mud/soil)
Common Locations
• Attics • Window frames • Furniture • Rafters • Any dry wood
• Crawl spaces • Foundation sills • Floor joists • Anywhere near soil
Entry Method
Fly in (swarmers enter through small gaps, establish colony)
Underground (build tubes from soil to reach wood)
Swarming Season
Late summer/fall (Warm afternoons)
Spring (After rain, warm mornings)

How We Treat Subterranean Termite Infestations

Subterranean termite treatment targets the underground colony, not just the visible damage.
We offer two proven methods: soil chemical treatment (immediate elimination) and bait station systems (colony elimination over time).
Your property’s specifics determine the best approach.

TREATMENT OPTION 1:
Soil Chemical Treatment (Termiticide Barrier)

How It Works

We create a continuous chemical barrier in the soil around and beneath your home. When termites pass through treated soil (either foraging or returning to colony), they contact the termiticide and die.

The treatment also prevents new colonies from entering.

Advantages

TREATMENT OPTION 2:
Bait Station System (Colony Elimination)

How It Works

We install monitoring/bait stations around your home’s perimeter. Stations contain wood monitors initially. When termites are detected feeding, we replace monitors with bait that termites carry back to colony. Bait disrupts molting process, slowly eliminating entire colony.

Advantages

Think You Have Subterranean Termites?

If you’ve spotted mud tubes, spring swarmers, or wood damage near your foundation, you likely have a subterranean termite infestation. Our licensed inspectors can identify the type of termites, assess the extent of damage, and recommend the most effective treatment—soil barrier, bait stations, or combination approach.

Common Questions About Subterranean Termites

Quick answers to the questions we hear most often. Don’t see your question? Call us at (650) 969-5556.

Less common than drywood termites, but definitely present. About 10-20% of termite infestations we treat in Silicon Valley are subterranean.

Subterranean termites are more common in:

  • Areas with poor drainage or standing water
  • Properties near creeks, wetlands, or retention ponds
  • Homes with irrigation system leaks
  • Older neighborhoods with mature landscaping
  • Properties on expansive clay soil (retains moisture)

Drywood termites are the primary concern in Silicon Valley, but if you see mud tubes on your foundation, you have subterranean termites and need treatment.

Look for these definitive signs:

You have SUBTERRANEAN if you see:

  • Mud tubes on foundation, walls, or crawl space
  • Swarmers in spring (dark brown/black with wings)
  • Damage in wood near ground level
  • Galleries packed with mud/soil

 

You have DRYWOOD if you see:

  • Pellet-like droppings (frass) near windows or in attic
  • Swarmers in late summer/fall
  • Damage in attic, rafters, window frames (above ground)
  • Clean, hollow galleries in wood Sometimes homes have BOTH types. Our inspection identifies which you have and recommends appropriate treatment for each.

Not recommended.

Here's why:

  • Professional-grade termiticides aren't available to homeowners (most effective products require licensed applicator)
  • Application requires specialized equipment (100+ gallon tank, rod injector, drill)
  • Incorrect application wastes money (gaps in treatment = termites find route)
  • Safety concerns (termiticides require proper handling, PPE)
  • Warranty issues (DIY treatment voids any existing warranties)

 

DIY products (foam sprays, spot treatments) rarely work for subterranean termites because:

  • They don't reach the underground colony
  • They don't create continuous barrier
  • Termites simply route around treated areas Subterranean colonies contain hundreds of thousands of termites. Professional treatment essential for elimination.

Yes, when applied correctly by licensed professionals.

Soil Treatment:

  • Modern termiticides (Termidor, Taurus, Altriset) have low mammalian toxicity
  • Applied in soil (not living spaces)
  • Binds to soil particles (doesn't leach into groundwater)
  • Pets and children can return same day after application
  • No odor, no off-gassing into home

 

Bait Stations:

  • Bait locked inside tamper-resistant stations
  • Stations installed in soil (not accessible to pets/children)
  • Bait only where termites feed (precision application)
  • Extremely low environmental impact

 

Precautions we take:

  • Use EPA-registered products only
  • Follow all label instructions precisely
  • Keep pets/children inside during application
  • Inform you when safe to resume normal outdoor activities (usually same day) If you have specific health concerns, discuss with us during estimate. We can address individual situations.
