How to get rid of ants in Del Mar, CA
Ants show up in San Diego kitchens and bathrooms almost year round because our mild winters never force a hard die-off. A single scented crumb or a damp patch under a sink is enough to pull a trail of them inside.
What you're dealing with in Del Mar
Argentine ants dominate San Diego County, forming huge interconnected colonies, with odorous house ants and pavement ants also common around foundations.
Del Mar mixes older cottages along Coast Boulevard with newer custom builds in Del Mar Heights and Crest Canyon. Roof rat pressure is high from mature landscaping and canyon adjacency, and HOA-managed neighborhoods require documented quarterly service records for compliance.
Why ants show up here
The marine layer keeps Pacific Beach, Point Loma, and Ocean Beach humid most of the year, and Argentine ant colonies stay active through winter instead of slowing down. Tight lot lines on older beach cottages mean one neighbor's colony easily becomes yours.
How to get rid of ants: step by step
- Trace the trail back to the entry point Follow the line of ants to the crack, gap, or door threshold they are using and mark it before you clean anything up.
- Wipe the trail with soap and water Ants follow a scent path, so breaking it with a soapy wipe-down slows the next wave while you find the real fix.
- Seal the entry points you found Caulk gaps around pipes, window frames, and foundation cracks. Argentine ants can use openings smaller than a dime.
- Cut off food and moisture sources Store sugar, pet food, and produce in sealed containers, and fix any dripping faucets or damp areas under sinks.
- Use bait stations, not spray, near the trail Slow-acting bait gets carried back to the colony. Sprays just scatter the trail and can split one colony into several.

Ants questions from Del Mar homeowners
Why do I keep seeing ants in my Del Mar kitchen even after I clean up?
The scent trail survives normal cleaning. Wipe with soap and water specifically, then seal the entry point, or the same trail keeps getting used.
Do ants in San Diego go away in winter?
Rarely. Our mild winters let Argentine ant colonies stay active year round, which is why they are one of the most common calls we get in every season.
Is store-bought ant spray a waste of money?
Spray kills the ants you can see but often splits the colony into several smaller ones. Bait that gets carried back to the nest works better long term.
