Good pest proofing removes three things pests exploit: access, food and shelter. Work methodically around the property instead of sealing random gaps after the first sighting. If a gap may contain an animal or active nest, identify the problem before closing it.
1. Start outside
- Keep waste containers closed and clean around spillages.
- Check gaps where pipes, cables and drains enter the building.
- Look at damaged air bricks, vents and door thresholds.
- Keep vegetation and stored items from creating hidden routes directly into the building where practical.
- Inspect sheds and external food stores for signs before moving items indoors.

2. Kitchens and food storage
Store vulnerable dry food in sound containers, clear food residues under appliances and cupboards, and rotate older stored food. Pantry pests can arrive inside packaged products, so proofing is not only about holes in walls.
3. Doors, windows and vents
Repair damaged screens, badly fitting doors and obvious service gaps. The aim is not to block ventilation: use suitable mesh or repair methods that preserve the function of vents and air bricks.
4. Lofts and roofs
Look for damaged soffits, roof-edge gaps, displaced materials and evidence around loft hatches. Do not work at height or seal an opening while an animal may still be inside. Squirrels and birds need particular care because welfare and legal considerations can apply.
5. Moisture
Persistent dampness can support silverfish, mites and other moisture-associated pests. Fix leaks, improve ventilation and address condensation where appropriate rather than treating the insects as an isolated problem.
6. Monitor after proofing
Proofing is more useful when you know whether activity has stopped. Keep an eye on new droppings, damage, insect monitors or repeated sightings. If evidence continues, there may be another entry route or the identification may be wrong.
Common mistakes
Sealing too early
Closing an active nest or animal entry point can trap animals or redirect activity into occupied rooms.
Blocking ventilation
Airflow openings should not simply be filled. Use a suitable proofing method that preserves ventilation.
Ignoring food and waste
Physical proofing is much less effective when reliable food sources remain available.
Assuming one gap is the only route
Rodents and insects can exploit multiple service penetrations and adjoining voids.
