Ant Control & Exterminators in San Diego & Southern California
Fast, reliable ant control across San Diego and Southern California. With 90+ years of experience, same-day service, and a 100% satisfaction guarantee, we don’t just clear the ants you see — we eliminate the colony behind them.
Common Ants in San Diego & Southern California
Not all ants behave the same — and effective treatment starts with correctly identifying the species.
Argentine Ants
by far the most common ant in San Diego and coastal Southern California. They form massive, interconnected colonies and trail indoors toward water and sweets, returning fast without colony-level treatment.
Carpenter Ants
large ants that tunnel into wood to build nests and are often mistaken for termites. They can cause real structural damage and call for a licensed inspector.
Odorous House Ants
give off a foul, rotten smell when crushed and frequently invade kitchens and bathrooms looking for moisture and sugar.
Fire Ants
aggressive ants with a painful sting, usually found in yards and open ground and more common inland than along the coast.
Identifying the species is what lets us eliminate the colony at its source — not just the ants you can see.
Signs You May Have an Ant Infestation
If you’re seeing ants regularly, a colony is likely nearby — and growing.
- Ant trails along walls, counters, baseboards, or your foundation
- Ants showing up in kitchens, pantries, or bathrooms
- Small piles of dirt or debris near cracks and entry points
- A rotten, musty smell when ants are crushed (odorous house ants)
- A surge in activity during warm weather or right after rain
Why Ants Are So Common in Southern California
Southern California’s mild, dry climate keeps ant colonies active almost year-round. In San Diego especially, constant landscape irrigation, dense neighborhoods, and a long warm season give ants a steady water supply and easy paths between properties.
When it turns hot or right after rain, ants move indoors searching for moisture and food — which is why even spotless homes end up with ant trails.
How Lloyd Pest Control Gets Rid of Ants
Our approach targets the entire colony — not just the ants you see.
Inspection
we identify the ant species, locate nesting sites, and map the trails and entry points around your property.
Targeted Treatment
we treat the exterior perimeter with professional-grade products and use baits that carry the treatment back into the colony.
Barrier Protection
we treat entry points and create a protective barrier so ants can’t re-establish trails into your home.
Ongoing Monitoring
recurring maintenance visits catch new activity early and keep colonies from rebuilding — included with our monthly plans.
The result: long-term protection, not temporary relief.
Residential Ant Control
We protect every kind of Southern California home:
- Single-family homes
- Apartments & condos
- Townhomes & duplexes
You can book a one-time treatment for an immediate problem — but because ants are a year-round, recurring pest here, most homeowners choose our monthly maintenance plan. Ongoing service keeps colonies from coming back between visits, so you stay protected all year instead of just clearing today’s ants.
Choose from:
- One-time treatments for immediate issues
- Monthly maintenance plans for year-round protection (recommended)
Commercial Ant Control
Ant problems in a business mean health-code risks, customer complaints, and disrupted operations. Lloyd helps Southern California businesses stay compliant and pest-free with discreet, scheduled service. We treat:
- Restaurants & food service
- Hotels & hospitality
- Retail stores
- Offices
- Apartment communities

Store-bought sprays kill the ants you see but not the nest. Argentine ants — the most common species in San Diego — build huge interconnected colonies, so unless treatment reaches the colony, foragers keep returning. We treat the colony at its source and protect the perimeter so they can't re-establish.
Yes. We apply most products around the exterior perimeter, and indoors we place treatments inside wall voids and cracks — away from living spaces, children, and pets. The exterior product we use shares its active ingredient with common topical flea-and-tick medications for dogs.
The Argentine ant. It dominates coastal Southern California, forms enormous colonies, and is the species behind most of the indoor ant trails our San Diego customers report.
Because ants are active here almost year-round, most homeowners get the best results from a monthly maintenance plan, which keeps colonies from rebuilding between visits. A one-time treatment can knock down an active problem, but ongoing service is what keeps you ant-free.
Yes, but carpenter ants are handled differently from common household ants because they nest in wood and can cause structural damage. A licensed inspector locates the nest and recommends a targeted treatment, similar to how we handle wood-destroying pests like termites.
