Remove Rodents and Seal Them Out for Good

Rodents cause more than nuisance activity. Rats and mice can contaminate food, damage wiring and insulation, and multiply quickly once they gain access to a structure. Effective rodent control requires both removal and exclusion—reducing current activity while sealing the building so rodents cannot return.

Pestcom Pest Management provides professional rodent control and exclusion services across southwest Idaho and eastern Oregon. Our goal is simple: stop the rodent problem you’re dealing with now and help prevent repeat infestations with a clear plan you can understand.

In the Treasure Valley, seasonal temperature swings and new construction can create new access points—especially around garages, crawl spaces, attic lines, and utility penetrations. That’s why we combine targeted removal with structural hardening and practical guidance so you can keep your home rodent-tight long after the first visit.

Why Rats and Mice Invade Homes

Rodents are driven by three needs:

• Shelter in attics, crawl spaces, wall voids, garages, and storage areas
• Food such as pet feed, pantry goods, bird seed, and garbage
• Water from plumbing leaks, condensation, irrigation, and outdoor sources

Common entry points include:

• Gaps under doors and worn door sweeps
• Utility and pipe penetrations
• Crawl-space vents and foundation openings
• Roofline, attic, and eave access points

Once inside, populations can grow quickly. That’s why lasting results usually require both removal and exclusion—not just a few traps.

Rodents We Commonly Treat

• House mice in kitchens, garages, and wall voids
• Norway rats burrowing near foundations, sheds, and landscape edges
• Roof rats using trees, fences, and utility lines to access attics and eaves

Each type of rodent behaves differently, so the strategy that works for house mice in a small crawl space may not be right for roof rats using tree limbs and utility lines. During our visit we look for droppings, gnaw marks, and runways that point to the specific species involved, then design placements and exclusion steps to match. This helps reduce wasted time on generic treatments and gives you a clearer plan for resolving the issue from first activity through final confirmation of control.

Signs of a Rodent Problem

• Droppings along walls or behind appliances
• Grease or rub marks on baseboards and edges
• Scratching or movement sounds at night
• Shredded paper or insulation used for nesting
• Chewed packaging, wiring, trim, or stored items

You may also notice unusual pet behavior (dogs or cats intensely watching a cabinet or appliance), or a faint ammonia-like odor from heavy activity in enclosed spaces.

Our Rodent Control Process

1) Inspection & Game Plan

We map travel routes, nesting zones, and entry points from foundation to attic, then provide a clear plan and timeline.

During the inspection, we also review sanitation conditions, storage habits, and vegetation against the home so we can explain which changes will have the biggest impact. Our technician walks you through what we’re seeing and what to expect during follow-up visits.

If you’re also dealing with broader pest issues, we’ll point you to the right service path (for example, spider control or seasonal stinging insects concerns) so everything stays coordinated.

2) Removal & Population Knockdown

Depending on activity and layout, we may use:

• Professional traps or tamper-resistant bait stations placed along active runways
• Interior placements in attics, crawl spaces, garages, and behind appliances when needed
• Exterior pressure-point placements where travel is confirmed
• Monitoring to verify activity drop-off

We focus first on areas where rodents are already moving so we reduce numbers quickly and safely. Between visits, we use fresh evidence—new droppings, updated rub marks, or lack of activity—to fine-tune placements until we see consistent improvement and ultimately no new signs.

3) Exclusion & Structural Hardening

Effective exclusion reduces the chance of repeat infestations by closing off access points and reinforcing vulnerable areas. Depending on the structure, we may:

• Seal utility penetrations, foundation gaps, and siding openings
• Adjust or replace door sweeps and weather-stripping
• Screen vents and openings with gnaw-resistant materials
• Reinforce high-risk chew points where activity is common

Because the Treasure Valley includes a mix of older homes and new builds, we tailor exclusion to the construction details and local conditions instead of applying a one-size-fits-all approach.

4) Sanitation Guidance & Follow-Up

We provide practical guidance you can implement right away, including:

• Safe cleanup steps for droppings and nesting material
• Storage and housekeeping recommendations to reduce attractants
• Rechecks to confirm the structure remains rodent-tight
• Maintenance options for ongoing protection

If you want long-term peace of mind, we can structure ongoing service so you’re not stuck reacting every season. For some properties, that’s the difference between a one-time cleanup and a lasting solution.

Typical Timeline

• Day 0–1: Inspection, setup, and exclusion priorities identified
• Days 3–7: Most properties see a noticeable drop in activity
• Week 2–3: Follow-ups, placement adjustments, and confirmation of control

Severity and structure layout can extend timelines, but many homes see fast improvement once entry points and travel routes are addressed.

Homes with long-standing infestations, multiple outbuildings, or heavy clutter may need additional follow-ups beyond the typical three-week window to fully verify control. We discuss these possibilities at the outset so you understand how the process may look for your specific property and can plan around access, pets, or sensitive areas. Because building designs and rodent pressures vary throughout the Treasure Valley, our goal is always to give you realistic expectations and a clear roadmap rather than promising a one-visit solution.
