Why Old Town Monrovia's Craftsman Homes Face 100-Year Termite Exposure
Old Town Monrovia's 1910s-1930s Craftsman homes have original wood construction—redwood and Douglas fir framing, wood porch columns, rafter tails, and board-and-batten siding—that has been continuously exposed to both drywood and subterranean termite pressure for 90 to 100-plus years. Raised pier-and-beam foundations allow subterranean termites to access sill plates and wall framing directly from below through soil; the same open foundation design allows drywood termite swarmers to enter attic spaces and wall voids through gaps in rafter ends and vents above. Monrovia Canyon Park's soil moisture from mountain runoff elevates subterranean termite activity in canyon-adjacent Old Town properties. Gold Line area redevelopment is disturbing established soil termite colonies, potentially spreading them to adjacent residential properties.
How LA Pest Pros Treats Termites in Monrovia Homes
Termite treatment in Monrovia begins with a full structural inspection of Old Town Craftsman homes, examining pier-and-beam foundation perimeters, crawl space timbers, porch column bases, and attic framing for drywood and subterranean termite evidence. Old Town historic district restrictions are assessed before recommending treatment methods; borate wood treatment and localized injection are non-fumigation options appropriate for designated historic properties. Central Monrovia ranch homes receive slab-perimeter assessment for subterranean activity. Alluvial fan soil from San Gabriel Mountains in Monrovia is well-drained but moisture from canyon runoff near the park creates elevated subterranean conditions near Old Town. All work includes written report for real estate disclosure and a 30-day callback.
