Ortho Ant B Gon Max: Which One? 7 Canadian Labels Compared

Spray, foam, granules, liquid, traps or gel? The seven Ortho Ant B Gon Max labels side by side: where each is allowed, ant hills, carpenter ants and repeat intervals.

We list seven Ortho Ant B Gon Max products, and each one has its own Health Canada registration and its own label. All seven are Domestic-class insecticides, but they are not interchangeable: they use different active ingredients, the labels allow them in different places, and the repeat intervals differ. This guide sets the seven Canadian labels side by side so you can match the product to the job. We don't rank them on how well they work — the labels are the source, and we quote them.

Short answer: which Ant B Gon Max is for what?

Ants on trails, baseboards and cracks inside the house: the Ant Eliminator Ready-To-Use spray (PCP 27201) or the Ant Killer Foam (PCP 33727), or one of the three baits — the Ant Eliminator Liquid (PCP 9167), the Ant Traps (PCP 23372) or the Ant & Roach Killer Gel (PCP 32560).
Outdoors only, around foundations, decks, patios, pathways and driveways: the Ant Killer Granules (PCP 33511). Its label says "FOR OUTDOOR USE ONLY."
Ant hills in driveways, patios and interlocking brick: the Ant Killer Foam, whose label says "For use outdoors to control ants in ant hills."
Carpenter ants: of the seven labels, only the gel's names them.
Cockroaches as well as ants: the gel and the Ant & Roach Killer Spray (PCP 33725).

The first four are sprays, foam and granules; the last three are baits. That split matters for one direction on the gel label, covered below.

Ant Eliminator Ready-To-Use (PCP 27201): where and how often

The label limits how you spray it: "Apply as a crack and crevice or spot treatment only." Indoors it lists building surfaces including cracks and crevices in walls, floors and ceilings, along and behind baseboards, behind appliances, around sinks, drains and pipes, and points of entry, and adds: "For ants, also spray trails and nests."

The repeat interval depends on where you used it. Inside: "Treatment must only be repeated after 7 days if pest problem persists or reoccurs." Outside, the label reads "For use outdoors on the exterior surfaces of buildings." and sets a longer wait: "Treatment must only be repeated after 14 days if pest problem persists or reoccurs."

Two restrictions to read before you start: "DO NOT apply when people, pets or livestock are present." and "DO NOT allow people, pets or livestock to enter treated areas until sprays have dried."

Ant Killer Foam (PCP 33727): cracks, voids and ant hills

The foam's label says: "This product is designed for applying into cracks, crevices or voids that are difficult to reach and where the insecticide won’t be mopped away." It covers three situations, each with its own directions: indoors, the exterior surfaces of buildings and patios, porches and decks, and ant hills outdoors ("For use outdoors to control ants in ant hills.").

For ant hills, the label lists hills, mounds, cracks, crevices, gaps, voids and trails in driveways, patios, sidewalks or interlocking brick, and says: "Stop spraying when the foam comes back out the crack or crevice."

Repeat intervals: 7 days indoors and in ant hills, 14 days on exterior surfaces, patios, porches and decks. Like the Ready-To-Use, its label says "DO NOT apply as a space spray or broadcast application." — it is for spot, crack and crevice or void treatment only.

Ant Killer Granules (PCP 33511): outdoors only

This is the one to reach for around the outside of the house, and only there: "FOR OUTDOOR USE ONLY. DO NOT use inside buildings." The label lists the outdoor areas as around buildings, decks, patios, pathways and driveways. Its current version (dated 2024-02-15) was updated for Health Canada's re-evaluation of pyrethrins and piperonyl butoxide.

The label gives three ways to apply it (values stated, not quoted):

Perimeter: 10–15 g per square metre (2–3 level teaspoons) in a 30 cm wide band around the foundations of buildings.
Broadcast: the same rate on ant runs, around nests, hills and mounds and other ant-frequented areas on decks, patios, pathways and driveways.
Drench: 20–50 g (4–10 level teaspoons) dissolved in 1 L of water, applied to a 1 square metre area around ant nest entrances.

For the perimeter and broadcast methods the label says "Apply in early morning." Repeat interval: "Treatment must only be repeated after 7 days if pest problem persists or reoccurs." And keep everyone off: "DO NOT allow people or pets to enter treated areas until product has dried (drench application) or until granules have settled."

Ant Eliminator Liquid (PCP 9167): drops of bait

The liquid is a bait, used in small amounts: "Apply as a spot or crack and crevice application only." The label defines the spot: "A spot application is an open, localized placement of bait in areas inaccessible to children and pets." For indoor or outdoor use: "Place drops on an impervious surface along the ant runs and in the cracks where ants are seen or at the entrance to the nest." Then, in capitals: "ONLY A FEW DROPS ARE REQUIRED." The label also says: "Repeat application after rain."

Ant Traps (PCP 23372): spacing inside and out

Each trap holds 5 g of bait, and the label carries an allergen line: "Warning, contains the allergen peanut butter." Before you set one out: "PUNCH ALL SIDE HOLES ON ANT TRAP."

Spacing differs by location. Inside the house: "Place traps 1.5 - 3 m apart where ants are numerous." Outside: "Place traps where ants enter dwelling, near ant hills in the lawn or garden 5 metres apart." Placement: "Use only in areas inaccessible to children and pets." And: "Replace traps as needed."

Ant & Roach Killer Gel (PCP 32560): the one that names carpenter ants

We searched the text of all seven labels: only the gel's mentions carpenter ants. Its use line reads: "For control of ants, carpenter ants and cockroaches, use indoors or outdoors in and around homes, apartments and condominiums." On timing, the label says: "The boron works slowly and sufficient bait should be made available for at least 14 days of continuous feeding." Our separate guide, Cockroach & Ant Gel Bait in Canada: How to Use Ortho Ant B Gon Max Gel, covers the gel's label in full.

Can you spray near ant bait?

Not near the gel. Its label says: "Do not use sprays, foggers or any chemicals or cleaners near the bait placements." If you are using one of the sprays or the foam along with a bait, keep them in separate places and follow each product's own label.

Ant & Roach Killer Spray (PCP 33725): ants and other crawling insects

The aerosol's indoor pest list includes ants, cockroaches, crickets, earwigs, firebrats, silverfish, sowbugs and spiders. If crickets are the problem, our guide Crickets in the Garage or House: How to Get Rid of Them, by the Label compares the labels that name them.

Are Ant B Gon Max products safe around kids and pets?

We don't make a safety claim; the labels set the precautions. The liquid bait's label says "KEEP AWAY FROM CHILDREN AND ANIMALS" and the traps' label "Use only in areas inaccessible to children and pets." For the Ready-To-Use spray: "DO NOT allow people, pets or livestock to enter treated areas until sprays have dried." If a pet gets into any of them, call your veterinarian and have the product's label with you.
