Carpenter ants hollow out damp or damaged wood rather than eating it, which means their presence often signals a moisture problem worth investigating too. Every Ant Control call in Crystal Lake starts with tracing the trail's direction rather than guessing, which is what keeps us from treating the wrong side of the colony.
A technician checks for carpenter ant frass and moisture damage in addition to standard trail mapping.


Every technician treating Crystal Lake properties for ants carries state licensing and full liability coverage.
We prioritize fire ant mound calls given the sting risk to kids and pets.
You'll know the full cost before any bait station or barrier spray goes down.
We use non-repellent insecticide and slow-acting bait so the colony carries product back to the nest instead of scattering.
Carpenter ants excavate damp or damaged wood for nesting, so treatment includes moisture-source identification alongside colony elimination.
Odorous house ants form large, fast-moving colonies with multiple satellite nests, so bait placement targets several access points at once.
Pavement ants nest under slabs, walkways, and foundations, so exterior perimeter treatment targets those specific access points.
Fire ant mounds get direct mound treatment plus a broader yard bait application to catch satellite colonies nearby.
Crystal Lake restaurants and retail spaces get scheduled bait monitoring to prevent recurring trails near food storage areas.
A perimeter barrier around the foundation reduces new trails from forming after the initial colony is addressed.

Call +1-866-315-0243 and describe the trail location — kitchen counter, foundation, or yard mound — for the right Crystal Lake dispatch.
Our mobile units stock separate bait types for carpenter, odorous house, pavement, and fire ants.
We trace the trail, identify the species, and quote a flat price covering interior and exterior treatment.
Guarantee coverage means continued trail activity after the guarantee window gets a free re-treatment.
We'd sprayed the visible trail ourselves for months with no luck. Non-repellent bait cleared the whole colony within two weeks.
Fire ant mounds near our kids' swing set got treated same-day, which was a huge relief given how close they'd built to the play area.
Having a documented ant program helped us pass our last health inspection without issue.
Pavement ants kept coming up through a crack in our patio slab every summer until the perimeter treatment finally sealed that off for good.

Nex Pest Control dispatches ant-specialized technicians throughout Crystal Lake and nearby communities, with species-specific bait stocked on every vehicle. Whether you're dealing with a single trail or a full yard of fire ant mounds, the same crew and pricing structure applies everywhere we service Crystal Lake.

Non-repellent bait works differently — ants carry it back to the colony, which is what actually eliminates the nest.
Carpenter ants prefer damp or already-damaged wood, so their presence sometimes points to a moisture issue worth checking.
Bait stations are enclosed and placed out of reach, and we'll walk you through placement locations during the visit.
Full elimination timing depends on colony size, but visible activity usually drops within the first week.
Fire ants are treated with both immediate mound knockdown and a longer-acting yard-wide approach.
Commercial ant programs include documented visits so you have records ready for any health inspection.
