California's newest city is also one of its most active ant markets — brand-new slabs, fresh landscaping, and open farmland on every side. Cornerstone routes have covered Mountain House through every phase of its growth.
Pests we see most in Mountain House
New construction and surrounding farmland make Argentine ants the dominant pest in every Mountain House village, with spiders, crickets, and earwigs close behind and wasps arriving each summer. We also treat cockroaches, silverfish, centipedes, and exterior fleas and ticks.
Where we work in Mountain House
Every village of Mountain House — Altamont, Bethany, Cordes, Hansen, Questa, Wicklund, and the newest phases — plus surrounding properties along Byron and Grant Line Roads.
