Kearny's character comes from its dense neighborhoods of attached row houses, two-family homes, and closely spaced older construction — many dating from the 1910s through 1950s. That density creates a specific termite risk that detached suburban homes don't face: a subterranean termite colony established in the soil beneath one unit can freely travel through shared soil to adjacent structures, feeding on multiple homes from a single colony.
If a neighbor has or had a termite problem, your risk is elevated — even if you've never seen a swarmer. June is when termite colonies are most actively expanding and feeding. Here's what Kearny homeowners and landlords need to know.
Key fact about attached homes: Subterranean termites don't respect property lines. They travel underground through soil, which is continuous beneath attached homes and row houses. A colony established under one unit can send foraging tubes into adjacent units without the adjacent homeowner ever knowing until damage appears.
Most people think of termite infestations as isolated to a single property. In Kearny's dense housing, that's rarely the case. Here's how colonies expand through attached structures:
Check the basement perimeter walls and any exposed foundation. Tubes climbing from floor to the sill plate or first-floor framing indicate active foragers.
Inspect both sides of basement party walls where they meet the floor. Termites often enter through the joint between the footing and the wall.
The sill plate — the wood beam resting directly on the foundation — is the most common first target. Probe with a screwdriver: soft or crumbling wood indicates damage.
Wings or dead swarmers on windowsills in spring = a mature colony inside the structure. Even if you didn't see swarmers, your neighbor may have — and that colony could be heading your way.
Treating termites in an attached home is more complex than treating a detached house, because the treatment must account for the continuous soil that connects multiple properties. Partial treatment — addressing only the affected unit — leaves the colony a path to re-enter from the adjacent untreated soil.
The most effective approach for attached homes is treating the full accessible perimeter of the affected unit with liquid termiticide, including both exterior and interior foundation walls and all penetrations. This creates a complete barrier without relying on the adjacent property to provide any protection.
When we find activity in one unit of an attached home, we always recommend that the adjacent units also be inspected — and in many cases, treated simultaneously. A coordinated multi-unit treatment is more effective and more economical than sequential single-unit treatments after the colony migrates.
We work with landlords, property managers, and condo associations in Kearny to coordinate building-wide inspections and treatment plans that address the shared-soil problem effectively.
Many Kearny landlords own two-family or small multi-unit buildings. For these properties, we recommend annual inspections regardless of whether tenants report problems — because tenants often don't notice the early signs, and by the time damage is reported, structural framing may already need repair. An annual inspection is far less expensive than an emergency structural repair.
