Ant Treatment & Prevention in San Francisco — FAQ

How much does ant treatment cost?+

A single ant treatment visit costs $150-$300 for a typical Sacramento home. Most infestations need 2 visits ($250-$500 total). Quarterly maintenance plans run $100-$200 per visit to prevent recurrence.

Why do ants keep coming back?+

Argentine ant colonies can number in the millions across interconnected super-colonies. Killing foragers with spray doesn't reach the queens. Professional baiting with transfer products kills the colony at its source.

Are the chemicals safe for kids and pets?+

Modern non-repellent insecticides are applied to exterior surfaces and dry within 30-60 minutes. Interior gel baits are placed in cracks and crevices out of reach. Follow your technician's re-entry guidelines (typically 30-60 minutes).

When are ant problems worst in Sacramento?+

Sacramento sees peak ant activity from March through October, especially during spring rains (which flood nests) and summer heat (which drives ants indoors seeking water). Preventive treatment before spring helps avoid infestations.
