Controlling ants and getting rid of them permanently requires understanding which species you’re dealing with and targeting the colony, not just the foraging workers you can see. Here’s a practical guide to ant control for BC homeowners.

Why Ant Control Is Harder Than It Looks

The ants you see trailing across your kitchen floor represent only a small fraction of the colony. The queen — who can produce thousands of eggs per day — remains deep in the nest, completely unaffected by surface sprays. Killing foraging workers provides temporary relief while the colony continues producing replacements. Effective ant control must reach the queen.

Identify the Species First

Different ant species require completely different treatment approaches. Carpenter ants require locating and treating the nest directly. Pavement ants and odorous house ants respond best to slow-acting gel bait. Pharaoh ants must never be sprayed — spray causes the colony to split and spread, dramatically worsening the infestation. Getting the species right before treating is essential.

What Actually Works for Getting Rid of Ants

Gel bait: Slow-acting gel bait is the most effective method for most indoor ant species. Workers carry the bait back to the colony, poisoning the queen and nest within 7-14 days. Place bait along active trails and near entry points. Do not use sprays alongside bait — they repel ants from bait stations.

Residual insecticide: For perimeter treatment and direct nest treatment, residual insecticide applied by a licensed technician provides effective knockdown and lasting protection against re-entry.

Exclusion: Seal cracks around the foundation, windows, doors, and pipe penetrations. Ants enter through tiny gaps — sealing them prevents re-infestation after treatment.
