One sighting does not show infestation size. Record physical signs and arrange inspection that addresses food, harbourage, entry and safe control together.

Signs can include droppings, gnawing, tracks, burrows, noises, rub marks and damaged food. Photograph with scale without touching droppings or carcasses. Note time, room and route.

A professional inspection identifies species/evidence, access points, food/water, neighbouring sources and risks. The plan may combine sanitation, proofing, monitoring and legally permitted control. Proofing timing matters: sealing while animals remain inside can create welfare, odour and damage problems.

Keep people and pets away from traps/baits. Follow written product and carcass-disposal instructions.

FAQs

Does one rat show the size?

No. Visibility depends on disturbance, food and behaviour. Inspection/monitoring estimate extent.

Why might rats return?

Food, harbourage, drainage or missed/reopened entry routes can remain after short-term control.

Suggested component

Use a Rat Evidence and Entry Map without automatic infestation scoring.
