How to Pest Proof an Apartment Effectively
Seal Every Structural Entry Point
The most important step in how to pest proof an apartment is eliminating pest access routes.

Damaged Air Bricks
Broken vents and unprotected air bricks allow rodents direct access into wall cavities.
Door Gaps
Install heavy-duty door sweeps on communal and external entrances.
Window Frame Cracks
Small cracks around sash windows provide insect access during warmer months.
Floorboard Voids
Older South West London conversions often contain hidden gaps beneath floorboards and skirting boards.
Using steel mesh, expanding sealants, and rodent-resistant fillers provides long-term protection.
