KNOW THE PEST. KNOW YOUR NEXT STEP.
Big ants around your home? Get help identifying them, understanding the signs, and deciding whether an inspection makes sense. Supernova serves wooded neighborhoods, rural properties, and homes across our Idaho and Washington service area.

Carpenter ants remove wood to make nesting galleries; their food includes insects and sweet materials such as honeydew. A parent nest may be outdoors in a stump or tree, with satellite nests elsewhere—including a building. That is why an inspection looks beyond the ants on the kitchen counter. Source: UC IPM.
Workers of common western species are often about ¼–½ inch long. Look for a single waist node and a smoothly rounded upper thorax in side view. Some are black; others have reddish coloring. Size or color alone is not enough to identify the species.
Winged ants have elbowed antennae, a narrow waist, and longer front wings than hind wings. Termite swarmers have straighter antennae, a broad waist, and wings of similar length. A clear close-up or collected specimen is more useful than guessing from a distance.
A carpenter ant indoors may be a forager from outside. It does not, by itself, prove there is a nest or structural damage in your home.

Photograph the ants and any debris, note the room and time of day, and tell us about leaks or previous treatments. Share what you have seen before disturbing a suspected nest or opening a wall.

LOCAL FIELD OBSERVATIONS
In our field work, we see more carpenter-ant activity around wooded properties in Spokane Valley, Coeur d’Alene, Athol, Hayden, Orofino, Kendrick, and Juliaetta. Trees, stumps, stored wood, and moisture are useful places to begin an inspection; a city name alone does not tell us whether a home has a nest.
For homes beside wooded lots and tree cover, tell us where you have seen ants around the house and yard.
Our local observations include wooded properties around Coeur d’Alene, Hayden, and Athol.

Orofino, Kendrick, and Juliaetta are also part of the wooded communities we inspect and treat.
Local observations supplied by Zach Leavitt, owner of Supernova Pest Control. These observations describe our service experience, not a measured ranking of infestation rates.
We identify the ants, inspect reported activity, and look for likely nesting sites, entry routes, and moisture conditions. Indoor and outdoor findings help us decide where to focus.
Depending on what we find, our approach may include targeted baiting and non-repellent treatments. We explain the recommended scope, access needed, and price before treatment.
We point out conditions that need attention and explain what to watch for afterward. Ask us what follow-up is included in your specific service recommendation.
Which plan fits? Start with identification and an inspection so we can confirm the scope of your carpenter-ant problem. Compare Shield, Strike, and Naturals to understand the general service options.
Repair leaks and damaged wood, improve drainage and ventilation, and keep gutters clear. Store firewood away from the house and off the ground. Keep branches from touching the structure and seal accessible entry gaps around utilities. These steps support control but do not confirm that an existing colony is gone. Prevention guidance: UC IPM and NC State Extension.
No. An ant may be foraging from an outdoor colony. Damage develops where ants excavate nesting galleries; its extent requires inspection. University of Minnesota Extension.
Not reliably. Worker sizes vary, so identification uses several features together. If you are unsure, start with a photo and our general ant guide.
Tell us where the ants are showing up and whether you have noticed trails, winged ants, wood debris, or moisture. We’ll help you choose a sensible next step.
