Cambridge's Exclusion-First Rodent Team

Rat droppings run larger, roughly rice-grain size or bigger; mouse droppings are smaller and more pointed, and noise timing differs too. A full inspection covers roofline and chimney access alongside the foundation, since rodents use whichever gap is easiest.

Yes — trapping clears what's inside now, but sealing is what keeps the next one from moving in. A thorough seal job on the first visit is what actually prevents a second call a few months later, which is why we'd rather spend extra time sealing than rush to the next job.

We'd wait — disturbed droppings can aerosolize particles, and our crew handles that with proper PPE.

A typical job is a single day plus a short recheck window.

We lean on traps and exclusion before rodenticide in most residential jobs.

Pet food left out and gaps around utility lines are frequent culprits we flag on inspection. We recommend a seasonal walk-around of the foundation, since freeze-thaw cycles can open new gaps.
