Spraying ant trails with repellent products is the leading cause of ants that keep coming back. The spray breaks up the colony into satellite nests. Show Me Pest Control's non-repellent bait protocol in Lexington reaches the queen -- the only way to actually eliminate the colony.

Non-repellent bait transfer technology, species identification, and perimeter treatment work together as a system.
Argentine ants, odorous house ants, pavement ants, fire ants, and carpenter ants all have different colony structures, nesting locations, food preferences, and responses to treatment products. Misidentify the species, apply the wrong product, and you get movement -- not elimination.
The active ingredient in non-repellent bait is undetectable to the ant. Workers carry it back to the harborage zone and pass it to other workers, to the queen, and to the developing brood. The collapse is colony-level, not surface-level.
Repellent products at the perimeter push ants to find new entry points. Non-repellent products let them walk through freely -- carrying the active ingredient into the colony. We use non-repellent formulations exclusively at the perimeter, maintaining the transfer mechanism that eliminates the population.
Carpenter ants do not eat wood -- they excavate it for nesting. Finding sawdust-like frass near wood members, hollow-sounding structural timbers, or large black ants near window frames may indicate an established carpenter ant colony in the wood structure. Void injection and perimeter exclusion are the correct responses.

What the spray kills is the forager -- the worker you can see. The workers you cannot see, the queen, and the developing brood are in a harborage zone that is typically behind a wall, inside a void, or in the foundation soil adjacent to the structure. The colony detects the repellent barrier and redirects around it, establishing new satellite nests on the far side. This is why ants treated with repellent products tend to appear in new areas of the home within 7 to 14 days.
Non-repellent bait transfer technology works through a mechanism called trophallaxis -- the food-sharing behavior through which ant workers pass nutrients to each other, to the queen, and to developing larvae. A worker that contacts non-repellent gel bait cannot detect the active ingredient and carries it back to the colony as a food source. The active ingredient is then transferred through the population during normal feeding behavior, reaching workers in the harborage zone, the queen, and the developing brood. Colony collapse begins within 3 to 10 days. The bait must be placed in the correct location -- inside or adjacent to the harborage zone, not on the foraging trail -- for the mechanism to function. Bait placed on a foraging trail is consumed by foragers and does not efficiently reach the reproductive core.
Sprayed multiple times and the ants are still there in Lexington? Call +1-866-315-0243. Our technician in Lexington identifies the species, selects the correct non-repellent bait, and places it in the harborage zone where the colony actually lives.
Consumer bait products have two limitations that professional treatments address. First, many homeowners contaminate their bait stations by applying repellent spray in the same area -- the colony detects the repellent and avoids the entire zone, making even correctly placed bait inaccessible. Second, colonies exposed to the same bait formulation repeatedly develop aversion, avoiding the attractant even when it appears fresh. Professional treatment uses bait formulations that rotate active ingredients and are placed in locations that have not been contaminated by prior repellent applications.
The frass produced by carpenter ants is diagnostic: coarser than termite frass, larger in particle size, and mixed with ant body parts and insulation fragments. Finding it near a structural wood member -- particularly in areas with prior moisture damage history -- indicates an active gallery. Surface spray applied to visible carpenter ant activity reaches foragers and not the gallery. Void injection, applied directly into the gallery through a small-diameter drill hole, delivers the active ingredient where the colony is physically located.
Recurring ant pressure in Lexington, IL is largely seasonal and predictable. Spring budding creates the maximum colony expansion pressure of the year. Summer heat and drought push foragers into cooled structures. Fall cooling brings foundation ingress. For properties that experience recurring annual infestations, a program that maintains a non-repellent perimeter through the spring and summer eliminates the conditions that allow colonies to establish inside the structure in the first place -- and is priced substantially below repeated reactive treatment costs.

Species ID determines bait formulation, placement location, and perimeter approach. We confirm it before selecting any product.
Professional-grade non-repellent gel bait placed in harborage zones and foraging corridors. Workers cannot detect the active ingredient and carry it back to the queen through trophallaxis.
The perimeter works by transfer, not by repulsion. Workers cross it, carry it, and bring it back to the harborage.
Carpenter ant treatment requires direct gallery access. Void injection delivers the active ingredient to the source -- not to the foragers you can see.
Professional fire ant granular broadcast applied in early season prevents the mound establishment cycle that produces dozens of active mounds by midsummer.
Spring, summer, and fall visits timed to address the colony expansion phases that produce indoor pressure. A prevention program is consistently more economical than repeated reactive treatments.
Four steps from initial contact to confirmed colony collapse.
Describe what you are seeing. We narrow the species before the visit and confirm on-site. The protocol is determined by the species, not a generic plan.
We locate the harborage zone before placing bait. The placement location is more important than the product.
Exterior non-repellent perimeter creates a second transfer pathway. Both treatments work simultaneously to collapse the colony.
Follow-up confirms activity trending to zero. If secondary nests are present, they are identified and treated at this visit.
Real outcomes from Lexington homeowners who had tried the spray approach first.
We had been spraying a trail every single day for three weeks. The trail kept reappearing in the exact same location every morning. Show Me Pest Control identified odorous house ants with a satellite nest inside the wall behind the dishwasher. Non-repellent gel placed inside the cabinet toe-kick cavity. Colony confirmed collapsed at the follow-up visit. We have not seen a trail since.
Hardware store baits stopped working after the second round. Show Me Pest Control explained the aversion issue -- colonies learn to avoid certain attractant compounds after repeated exposure. Different professional formulation, correct placement. The colony was gone in a week.
The coarse sawdust near my window frame turned out to be carpenter ant frass. Show Me Pest Control identified it correctly on the first visit, located the gallery, injected directly into the void. No new frass at the one-month follow-up. The other company I called first had no idea what they were looking at.
