Rodent & Mouse Control Guide (2026 Exclusion & Trapping Protocols)
Rodents infest over 21 million U.S. homes every winter, posing fire risks by gnawing electrical wires and carrying vector-borne pathogens.
Health safety guidelines and rodent-borne pathogen precautions align with the U.S. CDC Vector-Borne Disease Division and EPA Rodenticide Regulations.
Rodent Species Comparison & Behavior
| Species | Physical Features | Preferred Nesting Area | Nesting & Feeding Habits |
|---|---|---|---|
| House Mouse (Mus musculus) | Small (2–4 inches), pointed snout, large ears | Wall voids, kitchen cabinets, clutter | Curious; feeds on grains, seeds, processed food |
| Norway Rat (Rattus norvegicus) | Large (7–10 inches), heavy body, blunt snout | Basements, crawlspaces, ground burrows | Cautious (neophobic); burrowing nest builders |
| Roof Rat (Rattus rattus) | Slender body (6–8 inches), tail longer than body | Attics, rooflines, trees, upper floors | Agile climbers; fruit, nut, and seed preference |
4-Step Professional Rodent Exclusion Protocol
Poison alone will not solve a rodent problem if entry points remain open. A long-term solution requires complete structural exclusion:
- 1. Comprehensive Perimeter Inspection: Identifying all gaps larger than 1/4 inch (size of a pencil eraser).
- 2. Mechanical Sealing & Hardware Cloth: Filling gaps with copper mesh, steel wool, silicone sealant, and heavy-duty 1/4-inch galvanized hardware cloth.
- 3. Strategic Trapping & Removal: Placing snap traps and multi-catch stations along active travel runways (guarded by wall edges).
- 4. Sanitation & Attic Decontamination: Cleaning droppings with HEPA vacuums and applying enzyme disinfectants to neutralize pheromone scent trails.

Mice can squeeze through gaps as small as a dime (1/4 inch), while rats require 1/2 inch gaps. Common entry points include weep holes, pipe penetrations, damaged roof soffits, and door sweep gaps.
Initial rodent trapping and exclusion service averages $350 to $850 depending on home size and extent of structural repairs required.
