Rowhouses along Boulevard East, Palisade Avenue, and the cliff-side blocks. The wall-line strategy defines this work. We walk the property's exterior perimeter with the homeowner, identify active burrows and travel routes along the stone retaining walls, install tamper-resistant bait stations at the burrow heads and at intervals along the wall line, and treat individual burrows where active. Then we move to the building: identify every entry point at the foundation, the areaways, the steam vault grates, and the utility penetrations, and seal them with the right material for the gap — steel mesh and mortar at the foundation joints, copper or steel wool capped with sealant at the utility lines, replacement door sweeps and threshold work at the basement entries. Interior trapping closes out the existing population once the exterior is under control.
Walk-up rentals on the upper blocks. The walk-up rental stock concentrates house mouse pressure through the same vintage construction that drives the bed bug and cockroach work — radiator and pipe penetrations the construction never sealed, gaps along the baseboards, and unsealed service entries at the cellar. Adjacent-unit coordination matters here: mice travel between connected units through the wall voids, and treating one apartment without coordinating the building leaves the population to re-establish from next door. We run these accounts with the landlord on building-wide programs that hold the baseline rather than reacting to individual tenant complaints.
Central Avenue restaurants and food retail. The Central Avenue commercial spine has its own rodent profile — smaller scale than Downtown or Journal Square's alley pressure, but the same fundamentals. Restaurant and bodega alleys, dumpster lines, and dropped food feed Norway rat populations that then push into the surrounding mixed-use buildings. We run these accounts on monthly minimum service with HACCP-aligned documentation, mapped tamper-resistant exterior bait stations along the alley, sanitation coaching for operators, and pre-business-hours scheduling that respects the lunch and dinner rush.
Across all three building types the sequence is the same. We inspect first — species ID, exterior burrow mapping along the wall line, interior entry-point identification — document the conducive condition, and present a written plan before any work begins. Treatment is exterior-first: wall-line bait stations and burrow work, exclusion at the building entry points, and interior trapping once the exterior is under control. Follow-up at 14 to 21 days verifies the population has crashed.
