Think Spraying Will Fix It? Think Again.
Spend five minutes online and you’ll find dozens of DIY termite hacks—orange oil, boric acid, even homemade bait stations. The appeal is obvious: no appointment, no technician, no upfront cost. But what looks like a clever shortcut often turns into a costly mistake.
At Good Sense Termite, we’ve spent over 14 years cleaning up after DIY termite treatments gone wrong. In many Bay Area homes, the damage we uncover could have been avoided—if the infestation had been properly handled from the start.
Here’s what homeowners aren’t being told about DIY termite control—and why expert treatment is more than just a can of spray.
1. Misidentifying the Pest = The Wrong Treatment Plan
Not all wood-damaging pests are termites. Not all termites are the same.
Drywood termites live in the wood itself and leave behind frass (tiny droppings that look like pepper or sand).
Subterranean termites live underground and travel through hidden mud tubes.
Carpenter ants don’t eat wood but burrow through it to nest.
Misidentifying the pest leads to the wrong product, the wrong placement, and no lasting solution. We’ve seen homeowners treat for ants when they had termites—or apply orange oil to a problem buried two feet below the slab.
A free inspection from a licensed professional doesn’t just tell you if you have termites—it confirms exactly what you’re dealing with and where.
2. Most DIY Products Just Don’t Reach the Colony
Most hardware store products are limited by law to surface-only applications. California restricts the use of true termiticides (like fipronil or imidacloprid) to licensed professionals for good reason—they require safe handling, and they actually work.
DIY foams and sprays might kill what you see, but termites rarely stay in one spot. Subterranean colonies can stretch 15–20 feet underground. Drywood termites may be deep inside rafters, joists, or wall voids.
Killing the visible swarmers does nothing to stop the unseen workers still chewing through your structure.
3. DIY = Missed Entry Points, Hidden Activity
A termite colony only needs a crack the width of a credit card to get in. Some of the most common entry points in Bay Area homes include:
Planter boxes against siding
Deck attachment points
Cracked stucco near the foundation
Utility penetrations (gas, water, electric)
Slab expansion joints
DIY treatments typically target where the bugs are spotted—not where they’re actually coming from. And without attic or crawlspace access, you’re only guessing at how far the damage goes.
4. There’s No Monitoring, No Follow-Up, and No Warranty
Even if your DIY treatment appears to work short term, termites can (and often do) return. Professional termite companies offer something DIY never will:
Regular re-inspections
Warranties for re-treatment
Ongoing monitoring in high-risk zones
Long-term protection backed by licensed applicators
When you go DIY, there’s no backup plan. If the termites return, you’re starting over.
5. Code Violations and Safety Risks Are Common
Many homeowners unintentionally create risks by misusing termite products:
Using foggers in sealed spaces, which can be flammable or toxic
Applying boric acid without PPE
Trenching too close to foundations without proper drainage knowledge
Attempting “do-it-yourself fumigation” (yes, we’ve seen it)
There’s also the legal angle—unlicensed chemical application can violate California pesticide laws or void your homeowners insurance policy.

FAQ: DIY Termite Treatments
Q: Can I treat a small termite issue myself?
You can try—but small visible issues often mask a much larger infestation. A free inspection helps ensure you're not missing critical structural damage.
Q: Is orange oil effective?
Only in very limited, surface-accessible Drywood infestations. It won’t help against Subterranean colonies or anything behind walls, under slabs, or inside beams. Plus, orange oil requires direct contact with termites to kill, which limits it's effectiveness.
Q: Will DIY treatment affect my warranty?
Yes. Many professional termite warranties become void if non-professional products are used after treatment. It’s best to let your provider handle any future pest activity.
Final Thoughts: Termite Control Isn’t a Weekend Project
There’s a big difference between spot-treating pests and protecting a home. Termite control in the Bay Area requires experience, safe products, and a full understanding of where colonies live—not just where they show up.
