What a liquid barrier installation actually involves
It is a construction day more than a spraying day. The crew starts by clearing a working strip along the foundation, moving mulch, plants, and anything stored against the wall, then digs a shallow trench along the exterior. Termiticide goes into that trench at a labeled rate and the soil is replaced in treated layers so the zone is continuous. Where a patio, walkway, driveway, or porch slab meets the house, the concrete gets drilled at intervals and the product is injected underneath, then the holes are patched. Bath traps and slab expansion joints may need indoor drilling too. Gaps are the enemy. A treated zone with an untreated section is a doorway, and FDACS points out that termites can use cracks the thickness of a credit card to get in, so the detail work around utility penetrations matters as much as the volume applied. Ask for the finished job in numbers: linear feet trenched, holes drilled, gallons applied, and any areas the crew could not reach. Those exclusions are where retreatment calls usually come from.
Choosing between fumigation and spot treatment for drywood
The question is not which is stronger, it is whether anyone can define the boundaries of the infestation. West Indian drywood colonies are small, slow, and scattered, and a house can hold several independent colonies in different framing members with no visible connection. Spot treatment fits when evidence is confined to one identifiable area: pellets under a single window, a run of fascia, a detached garage door frame. Drilling and injecting that member is far less disruptive than tenting and can be done in a day. Fumigation earns its cost when pellets appear in more than one part of the house, when the attic shows kickout holes in several rafters, or when the framing simply cannot be inspected. It reaches everything inside the sealed envelope at once, which is the only real advantage, and a substantial one. Whatever you choose, get the recheck scheduled in writing. Drywood evidence returning six months later in a new spot is a common and frustrating outcome after a spot job.
How Jacksonville soil and rainfall affect treatment life
The same product does not last the same number of years everywhere, and this city sits at the demanding end. With around 50 inches of rain a year and average humidity near 75 percent, the soil beside a Jacksonville foundation spends much of the year damp, and a low average elevation of 16 feet means water does not drain away quickly in many neighborhoods. Moisture works on a treated zone in two ways. It moves product through the soil profile over time, and it keeps foraging pressure high because the conditions termites need are always present. That combination is why UF/IFAS gives such a wide range for soil termiticide protection, from two years to fifteen or more. The practical response is drainage. Getting roof water away from the wall, fixing an irrigation head that soaks one corner, and keeping soil below the siding line all extend the working life of whatever was applied. Ask the company directly what conditions on your lot would shorten the treatment and get those items listed on the proposal.
Reading a treatment proposal line by line
Start at the top, with the finding. The proposal should name a species or say identification is pending, and it should reference a diagram showing where evidence appeared. Everything downstream depends on that line being right, and in a state with 20 established termite species, vagueness there is a real problem. Next, the scope in measurable units: linear feet, drill holes, station count, or structure volume. A proposal without numbers cannot be compared to another proposal, and it also cannot be checked against what actually got done. Then the terms. What is the coverage period, what triggers a retreatment at no charge, what does the annual renewal cost, and does the agreement transfer if you sell the house. That last one carries weight when the median home value locally runs near $295,000 and buyers routinely ask for termite documentation. Finally, the exclusions. Inaccessible areas, detached structures, and repair work are the three items most often left out of the price and most often assumed to be in it.
Timing treatment around Florida swarm seasons
You can treat any month of the year here, but the calendar shapes both urgency and scheduling. February through April brings daytime flights from native eastern subterranean termites, which is when most homeowners first find wings indoors and call. May is the loudest month. UF/IFAS places peak Formosan swarming in May, shortly after sunset, and FDACS gives an evening window running April through July. A cloud of swarmers around a porch light in May is the classic Jacksonville discovery story, and it usually means a mature colony somewhere nearby, not necessarily under your slab. Summer and fall shift toward daytime drywood flights, which is when attic vents and unpainted trim matter most. University of Georgia material adds that the light southeastern subterranean swarms from July through September, so late-season flights are not automatically drywood. October through January is the quiet stretch. Activity underground continues, but the phones slow down, which makes it the easiest time to schedule a non-urgent job and get an unhurried inspection.
What happens after the crew leaves
Treatment is a start date, not an end date. For a liquid job, expect the treated zone to hold for years, and expect the company to want an annual inspection to keep the agreement alive. Keep the invoice, the diagram, and the product name together in one folder, because a future buyer or a future inspector will ask. For a bait system, the aftercare is the product. Stations only work while someone is opening them, reading them, and replacing consumed material, so put the service dates on your own calendar rather than assuming they will happen. After fumigation, watch for new evidence rather than assuming the story is over. Fresh pellet piles in a location that was not treated before mean a new flight found new wood, and the answer to that is prevention work on exposed trim. In all three cases, keep doing the boring maintenance: gutters clear, soil low, wood off the ground, leaks fixed. Every one of those extends what you already paid for.
