Residential Properties
They treated the apartment.
Three months later, you're hearing them in the walls again.
Standard treatment removes the colony that's there. Within weeks, rats from the surrounding block fill the same space again — because the food source didn't change and the territory is now open. Fertility management reduces how many move back in, until the cycle stops.
Start the 90-day programWhy residential properties in NYC and NJ face persistent pressure
Your building shares its block with the same population that keeps coming in.
A treated building in a dense city doesn't exist in isolation. The rats that come back after treatment aren't traveling from far away — they're already in the surrounding block.
Older building stock
Much of NYC and NJ's housing was built before modern construction standards. Foundation gaps, shared basement walls, and aging plumbing create entry pathways that are difficult to fully seal.
Subway and underground access
Buildings near subway lines or dense underground utility infrastructure face the highest replacement pressure. Rats use those corridors to move between buildings constantly.
Shared waste areas
Multi-unit buildings with shared trash areas create a persistent food attractant. Individual unit cleanliness doesn't offset a building-wide waste management gap.
Adjacent properties
A restaurant or empty lot on the same block elevates the local rat population for every building nearby. Your building's problem is partly a function of what's next door.
NYC tenant and landlord context
A rodent condition is an HPD violation. It stays open until a re-inspection confirms it's resolved.
NYC landlords are required to maintain buildings free of rodent infestation. A tenant 311 complaint triggers an HPD inspection. The violation stays open until a follow-up confirms it's been resolved — which means the standard treatment timeline matters. If the follow-up comes during a replacement cycle, the violation stays on the record.
For tenants: your landlord is responsible for rodent-free conditions. A documented pattern of complaints supports your right to a habitable unit.
NYC HPD Class B violation
Rodent infestation in a residential building is a Class B (hazardous) violation. The owner has 30 days to fix and certify. Multiple open violations affect the building's housing court record.
NYC 311 complaint history
Every 311 rodent complaint is logged against the building's address in NYC open data. Patterns of repeat complaints are visible to prospective tenants, housing court, and city enforcement.
New Jersey
NJ residential properties fall under local municipal housing codes. Tenant complaints route to local health departments. The obligation to maintain pest-free conditions is consistent across municipalities.
How the program works for residential
Two phases. Your existing exterminator stays.
The 90-day program adds a fertility management layer on top of whatever pest control is already running. Phase 1 clears the current colony. Phase 2 slows down what comes next.
Clear the current colony
Your current exterminator handles treatment. If a landlord doesn't have a vendor in place, we can connect with a licensed partner. Treatment records from this phase address the HPD violation documentation requirement.
Slow down the replacement
Evolve bait stations go in at entry corridors, basement areas, the exterior perimeter, and known travel paths. Made from cottonseed — EPA minimum risk, no secondary kill risk, safe for occupied residential buildings with children and pets.
Monthly monitoring documents declining activity over 90 days. That record shows a building under active, consistent management — useful for HPD certification, housing court, or just giving landlords and tenants confidence the problem is trending the right direction.
