Rodents in Walls · NJ • NY • PA
Hearing rodents in the walls? Identify the route before cutting or baiting.
Wall sounds can be mice, rats, or another connected route. We inspect sound location, evidence, attic and crawl and foundation paths, and utility openings before recommending the plan.
Find every entry. Mice fit through a quarter inch, rats through a half.
Rodents use small gaps and the same routes repeatedly. The inspection finds where they're actually getting in, separates active routes from old damage, and confirms the species.
Whole-structure entry inspection
Foundation gaps, pipe penetrations, gable vents, garage door seals, dryer vents, utility line entries, attic vents, soffit returns. Rodents use all of them.
Active vs old, separated
Fresh droppings, grease marks along beams or baseboards, gnaw evidence with sharp edges. Old damage gets noted but doesn't drive the active sealing plan the same way.
Mice or rats, identified
Droppings are the easiest tell. Mouse droppings are small and pointed. Rat droppings are larger and blunt-ended. The species changes the trap plan and the gap size we have to seal.
Clear the active rodents. Then seal.
Sealing without trapping leaves the existing rodents stuck inside, where they chew through drywall or wiring trying to find a new route out. Trapping clears the active population. Then the permanent seal happens.
Snap traps placed where the activity is
Placement is what makes traps work. Traps go on the active route based on droppings, grease marks, and gnaw evidence, not scattered around.
No poison
Poisoned rodents die where they nest, often inside a wall or insulation cavity. The smell takes weeks. The carcass attracts secondary pests. We don't use it.
Confirm activity is out
Trap activity drops, droppings stop appearing, no new chew evidence. Then the permanent seal happens.
This is where most rodent jobs go wrong.
Poison only. Dead rodents in the wall. The entry is still wide open.
What the shortcuts cost.
Poison instead of entry sealing
Rodents die where they nest. The smell takes weeks. The entry stays open and a new family uses the same gap next month. Poison treats the symptom and leaves the cause.
Sealed without trapping first
The rodents already inside are now stuck inside. They chew through drywall, baseboards, or wiring trying to find a new route out. The seal-out becomes a seal-in.
Sealed the obvious gap, missed the actual route
Mice need a quarter inch, rats need a half. The visible hole isn't always the one they're using. A patch on the wrong gap leaves the active route open.
Some rodent jobs end at the trap-and-seal. Some need cleanup of droppings, urine staining, and affected insulation. The inspection decides.
See what cleanup includesPermanent closure. Then we walk the structure.
Once the active rodents are out, every gap they were using gets closed for good. Steel mesh and outdoor hardware. Then the structure gets a walk-through. Cleanup of droppings or affected insulation when the area calls for it.
Steel-mesh closure
Quarter-inch hardware cloth for mice, half-inch for rats. Screwed not stapled, sealed for outdoors.
Final walk-through with photos
You see the closed gaps, the attic deck, and the existing insulation condition before anything else gets recommended.
Cleanup with photos when warranted
Concentrated droppings, urine staining, or affected insulation get a written cleanup plan with photos.
What homeowners say
“They showed me photos of everything they found, sealed every entry point, and the house has been silent since.”
Sarah M., Montclair, NJ
“They were the only company that actually got into the attic with me and showed me the problem instead of just pitching a price.”
Dave K., Staten Island, NY
“They cleared the infestation, cleaned the contamination, and got the attic inspection-ready fast. It saved the sale.”
Maria L., Bucks County, PA
