Why termite treatment costs what it does in San Marcos
San Marcos is mostly 1990s and 2000s tract construction through San Elijo Hills and off Twin Oaks Valley Road, and that newer building stock keeps most jobs predictable and toward the lower end of the price range. The exception is rental housing near Cal State San Marcos, where fast tenant turnover creates real bed bug pressure, and that's a different job than a standard ant or spider visit, with more prep and follow-up required.

Common questions about termite treatment cost in San Marcos
Why would a rental near Cal State San Marcos cost more to treat than a house in San Elijo Hills?
Bed bug treatment near campus rental stock takes more prep, more follow-up visits, and often a callback to confirm the job held, since turnover between tenants keeps reintroducing risk. A standard ant or spider treatment in a San Elijo Hills tract home runs closer to $149 to $249 for a one-time visit. Bed bug work runs higher because of the extra visits it takes. No trip charge applies either way.
