A tiny gap at a pipe, an ill-fitting door and a damaged vent are different repair jobs. Finding a possible opening does not prove it is in use; pair the building check with signs inside.
What evidence helps?
Record noises, food damage and sightings by room and date. Photograph accessible gaps with something for scale. Do not handle droppings or pull apart electrical and plumbing areas.
What can you do now?
Secure stored food and report repairs. Avoid sealing a route without confirming whether animals remain inside or whether the opening serves ventilation.
Details worth including in your enquiry
- A photo of each accessible gap with scale
- Different evidence from each room
- Which repairs must preserve ventilation
Describe observations in your own words and tell us about any treatment already used. Photos can be useful, but there is no need to take a risky close-up, handle droppings or disturb a nest. If a landlord, tenant or manager needs to provide access, say who can coordinate that before a visit is discussed.
Agreeing a useful next step
Ask for a plan that identifies the likely access route, control method, proofing specification and follow-up check. A quote should state who performs each repair.
Before agreeing work, ask for the proposed area and method, any preparation or temporary exclusion, the number of visits, the full price and what would lead to a follow-up. Product-specific written instructions take priority over a general article. Sending an enquiry or naming a preferred day does not make a booking.
A common question
Will blocking one gap solve the problem?
Only if it addresses the actual route and the rest of the plan is appropriate.
