Rodent Control 

How We Protect Your Property

Species Identification Before Treatment The single most important step in rodent control is identifying the species before deploying any traps or bait. Roof rats, Norway rats, and house mice require different strategies — different trap types, different placement heights, different bait selections, and different follow-up intervals. A snap trap on the floor won’t catch a roof rat living in the attic. We identify first, treat second.

IPM-Based Approach: Inspect. Exclude. Control. We locate entry points, assess the conditions sustaining the population — food sources, harborage, landscaping — and apply treatments precisely where they’ll be most effective. We share what can be corrected to support lasting control between service visits.

High-Rise and Commercial Expertise Rodent pressure in commercial buildings is rarely random. It originates from identifiable external sources — neighboring construction activity, dumpster proximity, utility corridors, and landscaping conditions adjacent to the structure. Our technicians provide accurate source attribution and help property managers navigate accountability between tenants and building ownership with clarity.

Residential and Multi-Family Properties From single-family homes with citrus trees and ivy to multi-unit apartment complexes — we inspect the roofline, subarea, and all exterior entry points before recommending a program. Ongoing service programs available for properties with persistent or recurring pressure.

The Janus Rodent Control Program

Rodent control isn’t a single visit. It’s a sequence — and skipping steps is why most programs fail.

Initial Inspection We start with a thorough walkthrough of your property — for a home, this includes the attic, garage, subarea, and full perimeter. We look for how rodents are getting in, where they’re living, and what’s attracting them. Entry points, active harborage, and conducive conditions — overhanging branches and vines that bridge to the structure, overgrown vegetation, wood piles, debris, and unsecured food sources — are all noted and discussed with you on the spot. We’ll tell you what we can address, what’s within your reach to correct, and where another tradesperson may be the right call. No surprises, no upsells you didn’t ask for.

Exclusion Identifying entry points during inspection is only half the equation. Where conditions allow, we seal them — closing the gaps, penetrations, and structural breaches that give rodents access to the building. For residential properties, that means roofline access points: overhanging tree limbs, utility lines, and damaged fascia are the primary entry routes for roof rats in the San Gabriel Valley. For commercial properties, ground-level gaps, dock doors, and dumpster proximity are the primary risk factors. Every entry point identified is documented and photographed. Property managers receive a written report of findings and corrective actions taken.

Trap Deployment and Monitoring Following inspection and initial exclusion work, traps are deployed in high-activity areas and monitored over multiple follow-up visits. We return several times to check activity, reset traps, relocate stations based on what the data shows, and assess whether pressure is declining. This is not a set-it-and-forget-it program.

Ongoing Maintenance For properties with active bait stations or traps in attics, subareas, crawl spaces, or mechanical rooms, we recommend monthly service — ensuring bait levels are maintained, traps are functioning, and new activity is caught early before populations reestablish. Quarterly programs are available for lower-pressure properties on a prevention schedule.

Additional Services Beyond trapping and monitoring, Janus can coordinate the full scope of post-rodent remediation — structural exclusion repairs, site disinfection, and attic insulation removal and replacement. Where specialized work is required, we refer trusted contractors we have long-standing relationships with. You get a qualified referral, not a cold search.
