Ant Control Services for Wausau Homes
From a sugar-ant trail in the kitchen to a job for a carpenter ant exterminator, one call covers finding the nest and treating it.
Ant Identification
Size, color, shape and where the ants travel tell the pro which ant it is, because each one needs a different plan.
Nest Location
Checks at dusk, following trails, looking for sawdust and tapping walls to listen for rustling.
Carpenter Ant Treatment
Light dust treatments put into wall voids through small holes, right where the colony lives.
Baiting for Small Ants
Sugar or protein baits placed along active trails, so workers carry them back to the queens.
Outdoor Treatment
A treated band around windows, doors and the foundation where ants come in.
Moisture Check
Wet spots under tubs, around sinks and toilets, or at roof leaks pointed out, so you can fix what drew the ants in.
A photo of the ants on the call helps.
Carpenter Ant Exterminator in Wausau: What Happens When You Call
A carpenter ant exterminator spends more time finding the nest than spraying. Here is how a typical visit for any kind of ant goes.
Identify the ant
Carpenter ants, odorous house ants and pavement ants each need a different plan. The wrong product can scatter a colony instead of killing it.
Find the nest
Carpenter ants are most active after dark, so the pro may check at dusk, follow trails, look for coarse sawdust and listen at the walls. Small ants are traced back along their trails.
Your price and plan, in writing
You hear what the ant is, where the nest is and what the treatment will cost. Nothing starts until you say yes.
Treat where the colony lives
Dust in wall voids, baits on active trails and an outdoor band around windows, doors and the foundation. The goal is the queen.
Check back
Ant baits work slowly and some ants have many queens, so a follow-up visit confirms the activity has stopped or adjusts the plan.

Ants in Wausau Homes: The Basics
UW–Madison Extension says carpenter ants bring more complaints from Wisconsin homeowners than any other insect. Workers are 3/8 to 1/2 inch long, they are most active between about 8 pm and 4 am, and winged ones swarm outdoors in late May and early June.
Carpenter ants inside between November and early March, winged ants coming from inside, or 15 or more workers a day in a room away from the kitchen usually point to a nest in the house. The tiny ants on kitchen counters are often odorous house ants or pavement ants walking in from a nest outside, looking for sweets, grease or pet food.

Pest Control for Ants in Wausau: DIY or Call a Pro?
A short trail of small ants in May is often a DIY job. Pest control for ants is worth a call when the colony is inside your walls or the ants are carpenter ants:
- Carpenter ants inside during winter
- Sawdust piles or rustling inside walls
- Winged ants coming from inside the house
- Ants keep coming back after weeks of baiting
- Ants in more than one room or floor
- A rental, restaurant or food business
If You Try Baits First
- Use sugar baits for small dark ants and protein baits for pavement ants, right on the trail.
- Don’t spray near the bait. It stops the ants from taking it home.
- Expect more ants for a day or two. That means it’s working.
- Skip foggers. They don’t reach a nest inside a wall.

What Affects the Price of Ant Treatment
Prices aren’t listed here because every job is different. We quote after seeing the problem, based on:
- The type of ant
- Where the nest is: in a wall, ceiling, door or outside
- How many rooms or floors have ants
- Whether wall voids need treating
- How many follow-up visits are needed
- The size and type of the building
Ask Before You Book
- Which ant is it?
- Where do you think the nest is?
- What will you use, and where?
- Is a follow-up visit included?
- What moisture problems should I fix?
Carpenter Ant Damage: What to Look For
Carpenter ants don’t eat wood. They dig smooth, clean tunnels in wood that is already damp or soft, which leaves it looking like Swiss cheese. UW–Madison Extension says the bigger problem is usually the moisture or rot that drew them in.
- Coarse sawdust mixed with insect parts below ceilings, cabinets or trim
- A dry rustling sound inside a wall or door, louder when you tap it, often at night
- Ants around a window or door frame, which can mean a nest in the frame or nearby wall
- Damp spots near tubs, sinks, toilets, leaky roofs or rotting sills
- Stumps, landscape timbers or boards on the ground near the house
Find the Nest First
If the nest can’t be found, long-term control is unlikely. A pest inspection looks for the nest and the moisture problem behind it, so the treatment goes where it counts.

How much is pest control for ants in Wausau?
That depends on the type of ant, where the nest is and how many visits it takes. A carpenter ant nest in a wall is a bigger job than a kitchen trail. We set the price after seeing the problem and give it to you in writing first.
Can pest control get rid of ants for good?
It can get rid of the colony you have. Keeping ants away long-term also means fixing moisture, sealing cracks and keeping mulch off the foundation, because new colonies move in from outside.
What is the hardest ant to get rid of?
Odorous house ants are tough, because a colony can have many queens and spread across several connected nests. Treating one nest often isn’t enough, so baiting and follow-up checks matter.
Do carpenter ants die in winter?
Outdoor colonies slow down and wait out the cold. If you see carpenter ants inside between November and early March, the colony is probably living inside your house.
Should I be concerned if I see carpenter ants?
A few in spring are usually scouts from outside. Be concerned if you see them in winter, find sawdust, see winged ants indoors, or count 15 or more a day in one room away from the kitchen.
Do I need an exterminator for carpenter ants?
Often, yes. The key is finding and treating the nest, which can be inside a wall, door or ceiling. Pros have the tools to locate it and treat wall voids with very little product.
Are ant baits safe around kids and pets?
Baits are used in small amounts, but keep them in closed bait stations out of reach of children and pets. We tell you which products we use and where we place them.
Are your ant control technicians licensed?
Yes. Every technician we send is licensed by the State of Wisconsin and fully insured.
