Mouse Control in South Jersey

House mice are the most common rodent call in South Jersey and the most underestimated. A mouse fits through a gap the width of a pencil, which means the question is never whether your house has mouse-sized openings. It is how many. Acorn Wildlife treats mouse control as a sealing job with trapping attached, not the other way around, and that is why our jobs end.

Short answer: We control mice by trapping the population inside while sealing every exterior gap larger than a quarter inch, from the sill plate to the roofline. We skip poison because poisoned mice die in walls and the openings stay open. The result is a sealed home covered by our Seal-Tight Warranty.

Sounds

Light, fast scratching and skittering in walls, ceilings, and cabinet voids, mostly at night. Quieter and quicker than rats, and often in several parts of the house at once.

Droppings

Rice-sized, 1/8 to 1/4 inch, pointed ends, scattered wherever mice travel. A single mouse leaves dozens per day, so quantity is not a headcount.

Nests & Gnawing

Shredded paper and insulation nests in cabinet corners, drawers, and wall voids. Gnaw marks on food packaging, wire insulation, and soft plastics.

Where They Get In

Gaps under garage doors, utility and AC line penetrations, sill plate gaps, dryer vents, and cable holes. Any opening a pencil passes is a mouse door.

Whole-Home Sealing: The Part That Makes Mouse Control Permanent

The rhythm of South Jersey mouse calls tells the story: our phone gets busiest from late September through November, when the first cold nights push outdoor mice toward heated structures. A home sealed in summer skips the fall rush entirely. A home that only trapped last winter joins it again.

Sealing Mice Out for Good

Every opening we seal is closed in materials mice cannot gnaw through: steel wool backed with sealant, hardware cloth, and metal flashing, never foam alone. The work carries the Acorn Seal-Tight Warranty: if rodents get back in through a repair we made, we come back at no charge.

✓  Sill plate and foundation gaps sealed at ground level

✓  Utility, AC, and cable penetrations packed with steel wool and sealed

✓  Dryer and crawl space vents fitted with hardware cloth covers that still breathe

✓  Garage door sweeps and corner gaps closed, because the garage is the most common first entry

✓  Roofline gaps checked too: mice climb, and attic mice are a real thing

Methods and materials live on our wildlife exclusion page and the foundation and crawl space and vents pages. After removal, cleanup and sanitization handles droppings safely: the CDC advises against dry-sweeping rodent droppings, and we follow their wet-cleaning protocol.
