Insects, especially ants, small spiders and even lizards, don’t need a big opening to start visiting. Tiny gaps under or around external doors are like invitations. You may clean and spray all you want inside, but if the entry points stay open, they’ll keep coming back.
By inspecting door frames closely – looking for light shining through, feeling for drafts, or even sliding a piece of paper under the door – you can spot where the gaps are. Simple fixes like door sweeps, weatherstripping, or rubber seals can block those tiny highways.
You also get a bonus benefit: fewer dust and draughts sneaking in. That can help keep interiors cleaner and more comfortable.
It’s easier to keep unwanted visitors out than to constantly chase them around the walls once they’re inside.
