Termite Treatment & Inspections in Jacksonville, FL | Golden Hour Pest Services
Termites don't announce themselves. There's no swarm of visible bugs crawling across your kitchen counter, no obvious moment where you think — okay, we have a problem. They work silently, inside your walls, under your floors, and along your foundation, and by the time most homeowners notice something is wrong, the damage is already done.
In Northeast Florida, that window of time matters more than almost anywhere else in the country. We have the warm temperatures, the humidity, and the sandy soil that subterranean termites thrive in — and Jacksonville sits right in the heart of it. Spring and early summer are when termite colonies produce swarmers, the winged reproductive termites that go looking for new places to start new colonies. If you've seen what looks like flying ants around your home recently, there's a decent chance that's exactly what they were.
Here's what to actually look for — and what to do if you find it.
Early Warning Signs of a Termite Infestation
The tricky thing about termites is that the signs that show up early are easy to explain away. A stuck door. A soft spot in the floor. A little bit of what looks like sawdust near a baseboard. People live with these things for months before connecting the dots.
Mud tubes along your foundation
Subterranean termites — the most destructive species in Florida — travel through pencil-thin tubes of mud that they build along the outside of your foundation, up concrete block walls, and across any surface connecting soil to wood. If you see these, it's not a "maybe" situation. That's a confirmed active colony.
Hollow-sounding wood
Tap along your baseboards, door frames, and window sills. Termites eat wood from the inside out, leaving a paper-thin shell on the surface. Hollow sound means hollow wood.
Stuck or warped doors and windows
As termites damage wood and moisture enters through that damage, door and window frames can warp in ways that make them hard to open or close. Easy to chalk up to Florida humidity — but worth a closer look.
Discarded wings near windowsills or light fixtures
When swarmers find a new nesting site, they shed their wings. Small piles of tiny, translucent wings near windows, doors, or light sources are one of the clearest signs a colony is trying to establish nearby — or already has.
Frass (termite droppings)
Drywood termites push their droppings out of small holes in the wood they're infesting. If you see what looks like very fine, granular sawdust — often near furniture, door frames, or wooden trim — that's frass, and it's a red flag.
Why Florida Homes Are Especially Vulnerable
Jacksonville's combination of warm winters, high humidity, and frequent rain creates near-ideal conditions for termites year-round. But a few specific housing factors make Northeast Florida homes particularly attractive:
Slab-on-grade construction — the most common foundation type in our area — gives subterranean termites direct access to your home through expansion joints, cracks, and plumbing penetrations in the concrete.
Older homes with original wood framing, especially those built before modern treatment standards, may have little to no chemical barrier remaining in the soil.
Mulch and landscaping placed close to the foundation creates a perfect moisture-rich bridge between the ground and your home's wood structure.
This isn't meant to alarm you — it's just the reality of living in Florida, and most homes can be effectively protected. The key is getting ahead of it.
What Actually Protects Your Home: Termidor vs. Baiting Systems
There are two main approaches to termite treatment, and they work very differently.
Termidor liquid treatment creates a continuous chemical barrier in the soil around and beneath your foundation. Termites don't need to find it or choose it — any termite that passes through the treated zone picks up the product and carries it back to the colony, where it spreads to others. It works quickly, covers the full perimeter, and provides long-lasting protection in the soil for years.
Baiting systems take a different approach. Stations are placed strategically in the ground around your property, where termites find and feed on the bait and carry it back to the colony. They're a lower-invasiveness option that works well for ongoing monitoring and prevention, and they're particularly effective as a long-term management solution after an active infestation has been addressed.
In some situations we recommend one over the other. In others, a combined approach gives you the most complete protection — liquid treatment for an immediate barrier, with bait stations providing ongoing monitoring around the property perimeter.
Our process always starts with a thorough inspection first, so any recommendation we make is based on what we actually find at your home — not a one-size-fits-all package.

Buying or Selling a Home? You Need a WDO Inspection
If you're in the middle of a real estate transaction in Jacksonville or St. Augustine, a Wood Destroying Organism (WDO) inspection isn't just a good idea — for VA and FHA loans, it's typically required by the lender.
A WDO inspection is a licensed, documented assessment of your property for termites, wood-rot fungi, and other wood-destroying organisms. It's different from a general pest inspection, and it needs to be performed by a licensed termite operator. At Golden Hour, we offer WDO inspections with fast turnaround — because we know real estate deals don't wait.
If you're a buyer, it protects you from inheriting someone else's termite problem. If you're a seller, getting one done proactively can actually help your transaction move faster and give buyers more confidence.
When to Call a Professional
If you've spotted any of the signs above, don't wait to see if it gets worse. Termite damage is cumulative — a colony that's been active for two or three years can cause structural damage that runs into the tens of thousands of dollars to repair. Treatment is almost always a fraction of that cost.
If you're not sure what you're looking at, that's exactly what a free inspection is for. Our team will walk your property, check the areas termites most commonly target, and give you a straight answer about what's there and what needs to happen next.
No startup fees. No pressure. Just honest answers from a local team that treats your home like our own.
Frequently Asked Questions About Termites in Jacksonville
What time of year are termites most active in Florida? Termite swarm season in Northeast Florida typically runs from March through June, peaking in April and May when temperatures warm up and humidity rises. However, subterranean termites remain active underground year-round — swarms are just when they become most visible to homeowners.
How can I tell the difference between termite swarmers and flying ants? Look at the wings and waist. Termite swarmers have two pairs of equal-length wings and a straight, thick waist. Flying ants have wings of different lengths and a pinched, narrow waist. Both tend to swarm near light sources. When in doubt, save a sample and call us — we'll tell you exactly what it is.
Does homeowners insurance cover termite damage? In most cases, no. Homeowners insurance typically covers sudden, accidental damage — not gradual damage from pests. That's one reason prevention and early detection are so important. Termite treatment is almost always far less expensive than structural repairs.
How long does Termidor treatment last? Termidor is engineered to remain active in the soil for years. The exact duration depends on soil conditions, but it's one of the longest-lasting termite treatments available, which is a big part of why we choose it over alternatives.
Can I treat for termites myself? Over-the-counter termite products don't come close to professional-grade treatments in terms of coverage, penetration, or longevity. Subterranean termite treatment — whether liquid Termidor or a properly installed baiting system — requires professional equipment, licensed application, and knowledge of where termites are most likely entering your specific home. It's not a DIY job, and with something as costly as termite damage, it's not worth the risk.
