Rats are remarkably capable at finding and exploiting small gaps, which is part of why an infestation can seem to appear from nowhere. Here's how they actually get in, and the entry points genuinely worth checking.
Why Rats Get In So Easily
A rat can squeeze through a gap roughly the size of a 50p coin, and their strong teeth let them gnaw through many common building materials to widen an opening further. This combination means genuinely small gaps that look harmless are often enough.
Common Entry Points Around a Property
- Gaps around pipework entering the building, particularly under sinks
- Damaged or missing airbrick covers
- Gaps around loft eaves and roof junctions
- Poorly sealed gaps around doors, particularly garage and utility doors
- Damaged drain covers or gaps in drainage systems
Garden and External Attractions
- Compost heaps, particularly those including food waste
- Bird feeders, since spilled seed is an easy food source
- Overgrown areas or dense ground cover providing shelter
- Sheds and outbuildings with gaps at ground level
Why These Entry Points Get Missed
- They're often genuinely small. Easy to overlook during a casual visual check.
- They're in less-visited areas. Behind appliances, under decking, in loft eaves — not places people check regularly.
- Rats can widen existing gaps. A crack that looked too small last year may not be this year.
- A proper inspection catches what a casual look misses. This is exactly why professional proofing assessments matter.
Why Understanding Entry Points Matters
- Removal alone doesn't help if the same entry points remain open
- Proper proofing addresses the actual cause, not just the current activity
- Reduces the likelihood of a new infestation establishing later
- A genuinely thorough assessment covers more than the obvious spots
