One of the most effective ways to keep pests out of your home, business, or agricultural property is by identifying and sealing pest entry points before an infestation takes hold. At Country Pest Solutions, we've seen countless cases where a small gap or crack has allowed rodents, insects, or other pests to gain access — causing significant damage and distress.
Pests don't appear from nowhere. Rats and mice can squeeze through gaps as small as a 10p coin. Wasps and bees find their way into roof voids through tiny cracks in mortar or gaps around pipework. Cockroaches enter through drains and utility gaps. By understanding how pests get in, you can take targeted action to stop them — often without the need for chemical treatments.
Gaps Around Pipes and Cables — Any point where a pipe, cable, or conduit passes through a wall is a potential entry point. These gaps are often left unsealed during construction or renovation. Rodents can gnaw them wider over time.
Damaged or Missing Air Bricks — Air bricks allow ventilation under floors but can become entry points if damaged or if the mesh is corroded. Rats and mice regularly use these to access sub-floor voids.
Roof and Soffit Gaps — Loose or missing roof tiles, gaps in soffits, and deteriorating fascia boards are common entry points for squirrels, birds, and bats. Wasps frequently nest in roof spaces accessed through these gaps.
Doors and Windows — Ill-fitting doors and windows, damaged seals, and gaps around frames are easy entry points for insects and even small rodents. Check the bottom of external doors — if you can see daylight, pests can get in.
Drains and Sewers — Rats are excellent swimmers and regularly enter properties through broken or poorly maintained drain systems. A damaged drain inspection cover or a missing rodent guard on a soil pipe is an open invitation.
Wall Cracks and Mortar Gaps — Older properties in particular can develop cracks in external walls that provide access for insects, mice, and even rats.
Once you've identified potential entry points, the next step is proofing. Common methods include:
- **Steel wool and expanding foam** — for gaps around pipes (rodents cannot chew through steel wool)
If you're unsure where pests are entering, or if you've already got an active infestation, it's best to call a professional pest controller.
