Trails run outdoors spring through fall, and come inside during a drought and again after heavy rain.
If a trail comes back a day after you sprayed it, wider than before, this is why. Argentine ants run enormous colonies with many queens, and neighboring nests cooperate rather than fight, so what you are looking at is one arm of something much bigger living outside and feeding on honeydew in the shrubs. A contact spray makes it bud: workers carry brood and queens away from the disturbance and you get more trails, not fewer. Bait is the only thing that reaches a queen.
Spring swarming season follows the warm, humid stretch from February through May
A defined line two or three ants wide, running the same route along a mortar joint, a cable or the top of a baseboard, busy at the same hours each day. That is not a scout, it is infrastructure. Walk it in both directions before treating anything, because one end leads outdoors to what they are feeding on and the other leads to what they are feeding it to.
Look at the sizes rather than the color. Every ant in the line being the same size, about an eighth of an inch and light to medium brown, narrows it quickly, because several of the other nuisance species in this county run obviously mixed sizes in the same trail. Uniform means this one, and this one needs bait rather than spray.
They nest near water rather than near food, which is why hunting the kitchen wastes time. Look under a potted plant, behind a dishwasher that has been weeping, along a bathroom baseboard, and outside in the mulch where a downspout discharges. In a county that takes sixty inches of rain a year there is no shortage of options, so the damp spot nearest the trail is the place to start.
The way they nest matches local landscaping almost too neatly. These ants hold shallow nests just beneath anything that traps a little moisture: pine straw and bark mulch banked against the foundation, the sand bed under a paver walkway, landscape timbers, the saucer under a potted plant on a patio. Because Red Hills soil dries off at the surface and stays damp a few inches down, those pockets remain usable right through a hot week when open ground has baked solid.
Weather pushes the traffic both ways, which is what confuses people. A dry stretch drives foragers indoors hunting for water, so the first trails show up in kitchens and bathrooms. Then a heavy storm floods the shallow nests and moves whole sections of the colony in under siding and into wall voids. The household ends up reporting ants in two quite different seasons and assuming they were two separate problems.
In multi-unit housing the scale runs away from people quickly. One colony can occupy the space behind the siding of an entire building, so a single apartment or one half of a duplex treating alone is working on a fragment while the remainder carries on exactly as before. Buildings need a coordinated job and a plan for the shared exterior, not a run of individual callouts.
Tallahassee's older duplex rows and garden-style complexes near the university create exactly this multi-unit pressure, and the same coordination gap shows up wherever siding meets siding. Out toward Southwood, property managers around Central Park and the stormwater ponds face the same trail problem despite newer construction. Even off Woodville Highway near Lake Munson, where lots run bigger, shared fence lines and utility easements let one colony service several households at once.
Tallahassee sits on clay hills near the Ochlockonee and St. Marks rivers, not on the coast, and the ground here rarely freezes. Homes near Killearn Estates or Bradfordville face slab foundations or crawl spaces, never basements, which shapes where subterranean termites and moisture pests actually get in. Leon County's mild winters slow pest activity but almost never stop it outright.
Odorous house ants. Both are small, brown, trail-forming ants that turn up on a kitchen counter, and the practical difference between them is smell. Crush an odorous house ant and you get an unmistakable rotten coconut odor. Argentine ants give off nothing more than a faint musty note. It is worth the two seconds it takes, because odorous house ants answer to a narrower bait strategy while an Argentine colony needs sustained baiting spread across a far larger area.
Bait is the entire strategy, and it has to be generous and then left alone. Liquid or gel bait goes down on the trails and near the moisture, foragers feed and carry it home, and it works through the colony to queens in nests nobody ever located. Expect the trailing to look worse for a day or two while recruitment builds, then fall away. Wiping the trail with a strong cleaner, or spraying it halfway through, throws all of that away.
Around the bait sit the changes that count for a great deal more than any product. Pull mulch and pine straw back off the siding, lift potted plants off the slab, fix the dripping spigot and the sweating supply line, cut the branch resting on the roof, and keep the treated band on the foundation rather than in the kitchen. Argentine ants live outside and merely visit, so the exterior is where a program either holds or comes apart. If a company offers to spray the trail and call it finished, ask them what happens in two weeks.
Killearn Estates and Killearn Acres both sit inland from the Gulf, closer to the clay hills than the coast, which means the pest pressure here follows a slower, milder pattern than south Florida sees. Frost knocks activity back in December and January, but it never fully stops through a Tallahassee winter.

Two things a homeowner can do outperform anything sold in a bottle: find the water, and stop wiping the trail. Sealing the gap where a pipe comes through under a sink, dragging mulch off the brick, and leaving a bait station untouched for a full week will beat a perimeter spray comfortably. The classic mistake is understandable and expensive. Spray what you can see, feel pleased with yourself, then find the colony has budded into two or three fresh locations and the trails now run through rooms that were clear the week before.

Breeds indoors. Needs a follow-up visit. This is the one that does not come in from the yard.
The one spider here worth real caution. The southern black widow is the one spider here worth treating as medically significant, and almost every bite comes from a hand going somewhere a hand does not normally go: into a meter box, a firewood stack, a plant pot stored on its side, under a deck rail.
Comes looking for you. Every stage bites. Most ticks sit and wait for something to brush past them.
Contact insecticide kills foragers and broadcasts danger, and a colony with many queens answers that by budding. Queens and brood get carried away from the treated area and start fresh nests close by, which is precisely how one trail turns into three. Bait works with the colony's own behavior instead of against it.
No. The pheromone in that trail is what keeps bringing more workers to the bait. Clean around it, leave the line itself alone until activity has dropped away, then wipe it down and seal whatever they were coming through.
A short-term rise is normal and usually a good sign, since recruitment to a food source is exactly how the bait gets carried back to the nest. Judge it at two weeks, not on day two.
A first visit with baiting and an exterior perimeter band, plus a return, runs an estimated $95 to $185 on a typical house, with ongoing quarterly service below that per visit. Multi-unit buildings get quoted on the whole structure, because treating one unit on its own does not hold. Guide ranges only.
Rental turnover around Tallahassee Community College and Tallahassee State College keeps bed bugs a steady concern here, not a seasonal one.
