How do you find where rodents are entering if the entry points aren't visible?

Our specialists use behavioral evidence — grease marks, travel patterns, droppings, and gnaw points — to trace activity back to its source. We open wall voids, pipe chases, and utility penetrations that standard inspections skip. K9 detection teams help confirm activity in areas that are structurally inaccessible. Entry point mapping is always the foundation before any exclusion work begins.

What materials do you use to seal entry points, and are they permanent?

We seal entry points using galvanized metal mesh as a structural backer, followed by mortar or professional-grade sealants appropriate to the surface. We do not use foam — it compresses, degrades, and rodents chew through it. Our exclusion work is designed to be permanent, though we recommend periodic structural monitoring because buildings shift and new vulnerabilities develop over time.

How long does it take to resolve a rodent problem?

It depends on the extent of entry points, the size of the population, and how long the problem has been active. Most situations see meaningful reduction in pest activity within the first two to three service visits. Full resolution — including completed exclusion work and confirmed absence of activity — typically takes four to eight weeks depending on the complexity of the structure.
