What Property Managers Should Document When They Find Signs of Pests During an Inspection
A property manager walks a unit, opens the cabinet under the kitchen sink, and finds droppings and a water ring on the particleboard. The next twenty minutes decide how much that finding costs.
Pest companies often get called with a sentence: "There are mice in unit 4B." That leaves the technician with little information before arrival. They may spend time locating evidence the manager already saw or need another trip with different equipment. A documented finding can help the team prepare and reduce avoidable repeat visits.
Here is what to capture while you are still standing in front of it.
Photograph the evidence three times
Take the same finding at three distances, in this order.
Wide. Stand back far enough to show the whole room or the whole exterior wall. This is the photo that tells a technician which unit, which side of the building, and which floor.
Medium. Frame the fixture, cabinet, or section of wall. This shows the relationship between the evidence and the plumbing, the vent, the slab, or the door.
Close. Fill the frame with the droppings, the mud tube, the gnaw mark, or the stain. Include a ruler or familiar reference for scale only if you can do so without contacting or disturbing the evidence. Photograph droppings without touching, sweeping, or vacuuming them; follow appropriate cleanup guidance separately. Scale helps a technician assess size, but photos alone may not establish the species or treatment needed.
Write down where, exactly
"Kitchen" is a room. A technician needs a position in that room.
Record the unit or address, the room, the wall or surface, and the height off the floor. If the building has a numbering convention for units and a consistent front-of-building reference, use them every time. On the exterior, describe the location relative to a fixed feature: "north wall, six feet east of the gas meter, at grade."
Note the date and the time of day, too. Rodent activity, ant trailing, and cockroach movement all change with the hour, and a technician deciding when to schedule the visit will use that detail.
Name the evidence type, and stop there
Describe what you saw in plain terms: droppings, shed wings, mud tubes, frass, live insects, gnaw marks, grease trails along a baseboard, a musty smell in a closet, or a rustling sound in a wall at night.
Resist naming the species. A manager who writes "termites" when the evidence is carpenter ant frass sends the office down the wrong path before anyone arrives. Photograph it and describe it, and let the technician make the identification. The one exception worth flagging by name is a swarm of winged insects indoors, which is time-sensitive enough to say out loud.
Capture the moisture conditions
Moisture can contribute to many pest problems. Document any water issues alongside the pest evidence.
Look for a slow drip at the supply line or the trap, a soft or spongy spot in the floor near a tub or shower, staining on a ceiling below a bathroom, condensation on cold-water lines, a running toilet, a clogged gutter, or a downspout dumping against the foundation.
Photograph any suspected water source in the same set as the pest evidence. Where moisture is contributing to activity, treatment alone may not address the underlying conditions. Reporting both together helps the office coordinate pest control and repairs. Pests and moisture are also high on the list of what city inspectors look for in rental units.
Look for the way in
Stand at the finding and work outward toward the exterior. Photograph any gap you find along that path: pipe and cable penetrations under sinks and behind washers, the dryer vent, gaps at door sweeps and garage thresholds, missing or torn window screens, soffit and roofline gaps, weep holes, and crawl space or attic access left open.
A quarter-inch gap admits a mouse. A half-inch gap admits a rat. Most of the durable fix in a rodent job is pest exclusion work — sealing those openings so the population has nowhere to re-enter — and photographs of suspected entry points can help a technician assess the likely scope. An on-site inspection may still be needed before quoting or choosing a repair.
Record what the resident tells you
Ask three questions and write the answers verbatim.
How long has this been going on? Where and when do you see or hear it? What has been done so far?
That last one matters more than it sounds. Over-the-counter foggers scatter cockroach populations and make a job harder. Store-bought bait already in place changes the treatment plan. Residents rarely volunteer this information, and they answer it readily when asked directly.
Note the conditions you can change without a technician
Some findings are housekeeping and some are structural, and the report should tell them apart.
Stored cardboard, pet food in open bags, standing water in trays and buckets, mulch piled against siding, vegetation touching the building, and firewood stacked against an exterior wall are all conditions a work order or a resident notice can resolve this week. Separating those from the items that need a licensed technician keeps the pest budget aimed at the work that requires it.
Send it as one packet
Assemble the photos, the location notes, the evidence description, the moisture findings, the suspected entry points, and the resident interview into a single message, and send it before you leave the property.
A packet like that helps a pest control office triage before dispatch: choose an appropriate technician, prepare likely materials, and assess whether exclusion work may be needed. It can make the first visit more productive and may reduce repeat visits, though inspection and pricing may still require an on-site assessment.
It also builds a record. A dated, photographed inspection history showing what was found, when it was reported, and what was done can help support the record in a security deposit dispute or habitability complaint. It does not, by itself, determine responsibility or resolve a dispute.
The habit is the point
The value here comes from doing it the same way every time. Same photo sequence, same location format, same six categories. Findings compare across inspections, patterns surface across a portfolio, and the manager who has been photographing the same cabinet quarterly notices the new stain immediately.
Fifteen minutes of documentation at the moment of discovery is the cheapest part of any pest problem.
Frequently asked questions
What should I photograph first when I find pest evidence?
Take a wide shot of the room, a medium shot of the fixture or wall, and a close shot of the evidence. Include a scale reference only if safe. Do not touch or disturb droppings to arrange a photo. That sequence records where, what, and approximate size.
Should I identify the pest myself?
Describe the evidence and photograph it. Species identification drives the treatment plan, and a wrong name in the work order sends the wrong materials to the property.
Why does the pest company ask about moisture?
Moisture can support many pests. Recording leaks, condensation, or standing water alongside pest evidence helps the team assess contributing conditions and coordinate any needed repairs with treatment.
What do I ask the resident?
How long it has been happening, where and when they notice it, and what they have already tried. Store-bought treatments already in place change the professional treatment plan.
How small a gap matters?
A quarter inch admits a mouse and a half inch admits a rat. Photograph any opening along the path from the finding to the exterior.
