Identify the animal before choosing the job
Rats are generally larger than house mice, but a young rat can be mistaken for a mouse. Different rat species have different body proportions and habits. A photograph and the location of activity are more useful than size alone.
Scratching in a ceiling may have several causes. Ask for evidence of the animal before agreeing to a service for a particular species.
Record activity at ground level and above
Droppings, gnaw marks, tracks, burrows and repeated routes can help locate rat activity. Some rats favour ground-level shelter, while others climb and use elevated spaces. Neither an upstairs sound nor a garden hole confirms the species.
- Record recurring signs around bins, stored food, outbuildings and roof access.
- Photograph from a safe position without reaching into a burrow or moving contaminated material.
- Tell the company which areas are shared or cannot be accessed.
Address food, shelter and access
Secure rubbish and animal feed, remove accessible food sources and reduce sheltered clutter. Arrange appropriate gap repairs. Do not dry-sweep or vacuum rodent waste before disinfection; consult CDC's cleanup instructions or a suitable professional.
Write down the boundaries of the quote
Rat control, exclusion, drain investigation, building repairs and specialist cleanup are not interchangeable services. Ask which are provided directly and which require separate arrangements.
Where activity crosses property boundaries, identify the person responsible for coordination. Compare how the company will assess progress and communicate new findings, including whether additional visits cost extra.
Three questions to take to a company
- What evidence confirms rats and their likely routes?
- Does this quote cover exclusion or only the current activity?
- Who arranges inaccessible-area inspection, repairs and cleanup?
