Treatment that reaches the colony under your house
Subterranean termites live in the soil, not the wood. Killing the ones you can see fixes nothing until the ground itself is treated.
Subterranean termite treatment in Bakersfield is a ground game. The colony lives in the soil, sometimes tens of thousands of insects deep, and sends workers up into your house through mud tubes: pencil-width dirt tunnels they build to stay moist while they travel. You’ll find the tubes on foundation stem walls, crawl-space piers, and garage walls, or discover the damage first and the tubes later.
How they get in depends on when your house was built. The raised-foundation homes in Bakersfield’s older central neighborhoods give termites a shaded crawl space full of piers, each one a ladder to the subfloor. The slab tracts built from the 1970s on trade that risk for a sneakier one: tubes come up through settling cracks in the slab and through the gaps around plumbing penetrations, inside the walls where nobody sees them. Either way, the yard irrigation that keeps lawns green through a Bakersfield summer keeps the soil moist enough for colonies to work all year.
The treatment logic follows from all this. Killing the termites in the wall today does nothing, because the colony in the ground replaces them tomorrow. The soil is the battlefield. If you’re still at the “is this even termites?” stage, the signs of termites guide covers the full evidence list before you commit to anything.
The liquid barrier, explained
A liquid soil treatment puts a continuous treated zone between the colony and your house. The crew digs a narrow trench along the foundation, treats the soil going back in, and drills through slabs or patios where concrete sits against the structure so the treated zone continues underneath. Done right, there’s no gap for foragers to walk around. “Done right” is the load-bearing phrase: a barrier with a two-foot gap behind the water heater is a barrier in name only, which is why the layout gets mapped before the first shovel of dirt moves.
The chemistry is the quiet hero here. Modern products in the Termidor class are non-repellent, meaning termites can’t detect the treated soil and don’t avoid it. They tunnel straight through, pick up the active ingredient, and carry it back on their bodies. Grooming and food-sharing spread it through the colony. That transfer effect is what separates today’s treatments from the old repellent barriers, which just pushed termites sideways until they found an untreated gap.
It’s honest to say what this doesn’t do. A barrier defends the structure and degrades the colony that keeps testing it. It doesn’t sterilize your whole yard, and it can’t stop a future colony from arriving years from now. It is the standard, proven answer for an active infestation in the termite treatment lineup, and it’s usually finished in a single day.
Baiting: slower, quieter, always watching
The other route is a ring of bait stations set in the soil around the house. Foraging termites find a station, feed on a growth inhibitor, and carry it home. The colony declines over weeks rather than days, but the effect reaches the colony itself, and the stations keep working as an early warning system long after.
Baiting earns its keep where trenching is impractical: finished landscapes nobody wants cut, drainage that would carry liquid product away, or properties where the owner simply prefers monitoring built in. It also suits homeowners who had a barrier installed years ago and want a second layer watching the perimeter. The trade-off is patience. A barrier starts working the day it goes in; bait works on the colony’s schedule, over weeks.
Whichever route fits, follow-through is the same: someone looks again on a schedule. A free inspection is how that cycle usually starts.
Mud tubes on the foundation? Have it looked at before the quote, not after.
Make sure it’s actually subterranean
One clarification saves Bakersfield homeowners real money: mud tubes mean soil termites, and no tent fixes a soil colony. Fumigation treats the wood and the air space inside a structure. The gas never touches a nest three feet under the back patio, so tenting a house for subterranean termites buys three days of disruption and zero control. The colony sends new workers up the week after the tent comes down, into a house that now believes itself treated. That false confidence is the expensive part.
The reverse mix-up costs too. Pellets under a window frame point to drywood termites, which soil treatment won’t reach; that’s a different treatment path entirely. If you’re not certain which insect you have, the drywood versus subterranean guide shows how to tell them apart before anyone quotes you anything.

Frequently Asked Questions
What do mud tubes on my foundation mean?
Subterranean termites are traveling between the soil and the wood in your house. The tubes protect them from open air on the trip. Scraping tubes off doesn't hurt the colony, so leave them for an inspector to evaluate first.
How long does a liquid soil treatment last?
Modern non-repellent products are made to stay active in the soil for years after application. No barrier is permanent, though. Soil gets disturbed by landscaping and plumbing work, which is why periodic re-inspection remains standard after treatment.
Is baiting better than a liquid barrier?
Neither wins everywhere. Liquid treatment puts protection in place immediately. Baiting works slower but doubles as ongoing monitoring, and it fits properties where trenching or drilling is impractical. The inspection findings usually point clearly at one.
Does having subterranean termites mean the nest is under my house?
Not necessarily. A colony can forage many yards from its nest, so the termites in your wall may be based in the yard, or a neighbor's. That's why treatment targets the colony through the soil instead of chasing the nest.
