Pavement ants are persistent. They follow cracks in driveways, foundations, and basement floors, building trails that seem to reappear overnight no matter how many you crush. The real problem isn’t what you see — it’s the colony hidden beneath the slab, and the only way to stop them is with a bait that worker ants willingly carry back to the queen.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve analyzed the active ingredients, bait station designs, and consumer test data across dozens of ant control products to separate the baits that actually eliminate pavement ant colonies from those that just kill a few scouts.
The right bait formulation targets the specific foraging preferences of pavement ants while remaining safe for indoor placement along baseboards and doorways. This guide breaks down the most effective options to help you find the best ant bait for pavement ants for your specific situation.
How To Choose The Best Ant Bait For Pavement Ants
Pavement ants are picky foragers. They prefer greasy, protein-rich foods but will also take sweets when the colony demands energy. The most effective baits exploit this dual preference by offering a matrix that contains both attractive food sources and a delayed-acting poison.
Active Ingredient Matters
Borax (sodium tetraborate decahydrate) is the gold standard for pavement ant baits. It works slowly enough that worker ants carry it back to the nest before dying, allowing the poison to reach the queen and the brood. Other active ingredients like abamectin or spinosad can work faster but may deter feeding if ants detect them too early.
Bait Station Design and Placement
Pavement ants need easy access. Look for bait stations with low-profile entrances that sit flush against baseboards or crack edges. For outdoor use, weatherproof stakes that push into the ground along the foundation line intercept foraging ants before they enter the house. Liquid baits often work faster because the moisture content attracts thirsty pavement ants during hot weather.
Colony Elimination Timeframe
No bait kills pavement ants instantly. Expect visible ant reduction within 3 to 7 days as worker ants distribute the poison through trophallaxis — the mouth-to-mouth food sharing that defines colony behavior. If you see dead ants near the bait station within the first 24 hours, the poison is acting too quickly and won’t reach the queen. A properly formulated bait triggers a gradual decline over two weeks.

In-Depth Reviews
1. Ortho Orthene Ant Killer Ant Bait
Ortho Orthene targets pavement ants with a bait formulation that worker ants cannot resist. The active ingredient delivers a delayed kill, giving foragers enough time to transport the poison back to the colony and share it with the queen. Users consistently report visible ant activity reduction within 3 to 7 days, with full colony elimination following within two weeks. The 24 bait station bundle provides generous coverage for multiple rooms or a large foundation line.
The bait stations are designed for discreet indoor placement along baseboards, in cabinet corners, near pipes, and on window sills. The low-profile plastic housing prevents accidental spills and keeps the bait secure from children and pets. Setup requires simply breaking the stations apart and placing them label-side down in active foraging zones.
User reports highlight the bait’s superiority over competing brands when pavement ants are being particularly selective. One reviewer noted that Ortho Orthene worked immediately when other baits failed earlier in the season, which suggests the formulation contains an attractant that aligns well with pavement ant feeding cycles.
Why it’s great
- Fast colony elimination in under a week for most infestations
- Large 24-station pack covers multiple problem areas simultaneously
- Mess-free placement with no liquid handling required
Good to know
- Not labeled for fire, carpenter, or harvester ants
- Stations can be difficult to remove if the plastic tears
2. Terro T1812-2 Outdoor Liquid Ant Killer Bait Stakes
Terro’s outdoor stakes intercept pavement ants before they ever reach the foundation. Each stake contains a borax-based liquid bait that attracts foraging ants and uses a slow-kill mechanism to allow transport back to the colony. The weatherproof housing protects the bait from rain and sprinklers, maintaining potency through multiple wet-dry cycles across the season.
The stakes push directly into the ground along the house perimeter, garage edges, or beneath decks. A tiered bait reservoir increases consumption over time, and the transparent window lets you monitor liquid levels without disturbing the station. The 2-pack contains 16 stakes total, enough to create a continuous barrier around a standard-sized home.
Real-world feedback confirms ants begin feeding within 15 to 30 minutes of stake placement. Users report a major decline in pavement ant activity within 3 to 4 days, with the stakes remaining effective for up to 6 months before needing replacement. One reviewer successfully used them around a chicken coop to protect feed from swarming ants.
Why it’s great
- Stops ants outside before they enter the house
- Weatherproof stakes withstand rain and sprinkler water
- Slow kill ensures poison reaches the queen through colony sharing
Good to know
- May need more frequent replacement in high-heat or very wet environments
- Liquid bait can attract non-target insects like flies
3. TERRO T300-3SR Liquid Ant Killer – 3 Pack
TERRO’s liquid ant killer is the most widely recognized bait in the category, and for good reason. Each station contains a borax-based liquid that targets sweet-feeding ants, which pavement ants actively seek when the colony needs quick energy. The bait attracts worker ants within hours, and they begin transporting it to the nest immediately. Users consistently report colony elimination within 3 to 7 days.
The 3-pack includes 18 total bait stations, providing extensive coverage for multi-level homes or apartments. The ready-to-use design requires no mixing or activation — simply peel the foil seal and place the station in an active ant trail. The enclosed housing prevents spills and keeps the liquid bait contained, which matters for interior placement along baseboards and countertops.
Customer reviews highlight the bait’s reliability across multiple ant species, including pavement ants. One user noted that a single gel pack eliminated an entire infestation in a large apartment within days, with no ants returning the following spring. The main caution involves liquid leakage if stations are inverted or handled roughly.
Why it’s great
- Works on multiple ant species including pavement ants
- Borax formula is proven with decades of successful use
- Large 18-station bundle offers long-term supply at a practical cost
Good to know
- Spilled liquid can cause skin irritation if contacted directly
- Best kept away from pets due to borax content
4. Pic HomePlus Ant Killer 6-Pack
Pic HomePlus uses a child-resistant metal bait station that distinguishes it from plastic alternatives. Pavement ants enter through small openings at the base, consume the bait matrix, and return to the colony. The metal housing resists crushing from pets and prevents accidental breakage, making it suitable for garages, patios, and basements where plastic stations might get damaged.
The bait contains four different food-source attractants, which increases the likelihood that pavement ants will find it appealing regardless of their current dietary preference. Users note that the bait stations remain effective even during heavy rain when placed outside between screens and window glass. One reviewer reported that a single 6-pack kept ants away for an entire spring-through-fall season.
The bait does not contain any of the seven major allergens, making it a viable option for households with food sensitivities. The metal can construction allows for placement under rocks or bricks without concern for the station collapsing under weight, and the child-resistant opening mechanism adds an extra safety layer for families with young children.
Why it’s great
- Metal bait stations resist chewing from dogs and other pets
- Child-resistant design adds safety for family households
- Four food-source attractants improve bait acceptance by pavement ants
Good to know
- Holes require opening with a pen or screwdriver before use
- May not be as fast-acting as liquid bait alternatives
5. Maggies Farm Ant Bait Station
Maggie’s Farm offers a gel-based bait station that prioritizes pet safety without sacrificing effectiveness against pavement ants. The gel formulation contains a non-toxic active ingredient that targets the ants’ nervous system without posing a risk to cats or dogs who might investigate the stations. This makes it an ideal first-line option for households with roamers.
The 6-count pack provides adequate coverage for small to medium-sized rooms. Users report that placing the stations along walls and near entry points produces visible results within 2 to 3 days. The bait stations have no unpleasant odor, which is a common complaint with spray-based ant killers. One reviewer noted that the gel stations eliminated camper ants in under two days, outperforming larger national brands.
The main limitation is that the gel can dry out over time, reducing effectiveness after 3 to 6 months. Some users have revived dried stations by adding a few drops of water, but for best results, you should plan to replace them at the start of each ant season. The stations are manufactured in the United States, which may appeal to buyers seeking domestic production.
Why it’s great
- Pet-safe formula works near cat feeding stations and dog beds
- No odor during use, suitable for indoor kitchen placement
- Fast-acting gel attracts pavement ants within hours
Good to know
- Gel dries out after several months and needs replacement
- 6-pack covers limited areas compared to larger bundles
