You’re not alone if you’ve spotted ant trails across your Boise kitchen floor, bathroom sink, or patio during the summer months. In fact, ant infestations are one of the most common pest problems Boise homeowners face during warm weather.
From the North End to Southeast Boise and everywhere in between, summer creates the perfect storm of conditions for ants to invade your home: rising temperatures, outdoor food sources drying up, and easy access through foundation cracks or poorly sealed doors.
At Candor Pest Control, we receive dozens of service calls each week during the summer from Boise families overwhelmed by ant activity. In this post, we’ll cover:
- The types of ants common in Boise
- Why infestations spike in summer
- How ants are getting inside
- What homeowners can do to stop the problem
- When it’s time to call a local pest expert
What Kind of Ants Are Invading Boise Homes?
Not all ants behave the same. Here are the top species you’re most likely to deal with in Boise:
Odorous House Ants
- The most common nuisance ant in Idaho homes
- Small, brown to black in color
- Give off a rotten, coconut-like odor when crushed
- Attracted to sugary substances
- Nest indoors near moisture—under sinks, behind walls, around leaky pipes
Pavement Ants
- Often found around driveways, patios, sidewalks, and basement floors
- Build nests in cracks in pavement and foundations
- Tend to enter through slab gaps or utility lines
- Feed on a variety of crumbs, oils, and pet food
Carpenter Ants
- Larger ants (¼–½ inch long)
- Nest in wood, especially if it’s damp or decaying
- Unlike termites, they don’t eat wood—but they carve tunnels through it
- Can weaken wood structures over time
- Most active at night and often found in walls or attic spaces
Why Are Ants Worse in the Summer in Boise?
Ant colonies go into overdrive during the summer. Here’s why:
1. Heat Drives Ants Indoors
When Boise hits triple digits in July and August, ants seek relief just like we do. Homes provide a cooler, stable environment—and access to water and food.
2. Unpredictable Weather Patterns
Sudden thunderstorms or droughts push ants to relocate their nests. Foundations, basements, and crawl spaces are prime real estate.
3. Foraging Season Peaks
Ant colonies expand aggressively in summer and need more food. Worker ants venture farther indoors to meet the growing demand.
4. Cracked Foundations and Gaps Get Worse
As homes shift and settle with the heat, gaps around doors, windows, and foundations widen—giving ants easy access inside.
How Ants Are Getting Into Your Boise Home
Ants don’t need an open door—they only need a fraction of an inch. Here are the most common entry points we find during inspections:
- Unsealed baseboards and trim
- Gaps under exterior doors or garage doors
- Holes in foundation vents or crawlspace access panels
- Plumbing and utility line entry points
- Cracks in stucco or siding
- Poorly sealed windows
Why DIY Ant Control During June and July our Meridian team handles ant calls on a near-daily basis, with odorous house ants being the most common species homeowners bring to us. in Boise Rarely Works Long-Term
You might be tempted to grab a can of store-bought spray or set out bait stations. While these can provide short-term relief, they often don’t fix the real issue.
Common DIY Pitfalls:
- Spraying ant trails scatters the colony instead of eliminating it
- Using the wrong type of bait for the ant species
- Not targeting the nest—only surface foragers
- Overlooking hidden nests behind walls or in crawlspaces
Note: Carpenter ant infestations often go undetected until real damage is done. Professional inspections are critical for long-term protection.
Signs You Have an Ant Infestation (Not Just a Few Strays)
- Visible trails that appear repeatedly along baseboards or countertops
- Piles of dirt or sawdust (may indicate nesting activity)
- Consistent sightings in kitchens, bathrooms, or laundry rooms
- Hollow-sounding wood (a sign of carpenter ants)
- Stray ants even after cleaning—a signal of a nearby nest
