Ant control cost in Kensington, San Diego
Ant control in San Diego runs $149 to $249 for a one-time treatment, and it is included in any quarterly recurring program at no extra charge. Argentine ant supercolonies are the usual target here, and they need to be knocked down at the colony, not just wiped off the counter.
The homes around Marlborough Drive, Adams Avenue, and the Kensington Park blocks carry original wood behind thick stucco, so drywood termite inspection and roof-rat exclusion around tile roofs lead the work. Mature gardens keep Argentine ant trails running through spring and summer, and the canyon-adjacent streets see the most rodent activity.
What ant control costs
What changes the cost in historic urban core homes
The work centers on drywood termite inspection and local treatment on original wood-frame stock, interior roach and rodent exclusion where old walls and plumbing chases give pests a highway, and knocking ant colonies down at the source instead of chasing trails across a counter.

- Interior versus exterior-only treatment
- Carpenter ants in structural wood cost more than nuisance ants
- Recurring service folds ant control in at no added cost
What drives the price in Kensington
The species and the approach set the price. Argentine ants, the ones that trail across San Diego kitchens by the thousands, respond to colony baiting and a perimeter barrier for $149 to $249, and spraying the visible trail without treating the colony just moves them. Carpenter ants are different: they tunnel structural wood and need targeted treatment quoted on-site. Because Argentine ant pressure is relentless in our climate, folding ant control into a quarterly program usually costs less over a year than repeat one-time calls.
How to keep the bill down
Do not spray the trail. Killing the ants you can see leaves the colony intact and often splits it into more trails. Colony baiting plus a recurring perimeter barrier is what actually ends it, and keeping food sealed and landscaping trimmed off the house removes the reasons they come inside.
Ant control cost questions
What does ant control cost in Kensington?
Most Kensington homes land in the $149–$249 range. The pre-war wood framing behind the stucco draws drywood termites, tile roofs and mature landscaping give roof rats and Argentine ants harborage, and the canyon edges toward Ward Canyon push rodents into the back blocks., which is the main thing that moves the number here.
Why not just spray the ants I see?
Spraying the visible trail kills a fraction of the colony and can cause Argentine ant colonies to split and spread. Colony baiting takes the treatment back to the nest, which is what actually stops the trail for good.
Is ant control included in recurring service?
Yes. A quarterly general pest program covers Argentine, odorous house, and common ants at no extra charge. Only severe structural carpenter ant work is quoted separately.
