Rodent proofing: closing the ways in
The best solution against rats and mice is making sure they cannot get in. A rat needs an opening of two centimetres, a mouse gets through six millimetres. With proper proofing we close those routes, so the animals do not get the chance in the first place, and no product is needed.
Where the openings usually are
In an average Dutch house we find between five and fifteen: at the meter cupboard, along the gas pipe, under a threshold, at the crawl space hatch, behind the downpipe, at broken air bricks and where the roof boarding does not close properly. Nine out of ten are at knee height or below, which is why we search there first.
What we seal with, and what we never use
Steel mesh, mortar, replacement vents and brush profiles: materials that cannot be gnawed through. We do not use expanding foam or tape, because a rat gets through both in a single night. Every point we close is photographed before and after, so you can see what was done.
The best moment to do it
August and September, ahead of the autumn migration indoors. From late September onwards mice move into buildings in large numbers as soon as the nights turn cold and there is less to find outside. A house that is closed by then comes through the winter without trouble.
Proofing without an active problem
You do not need an infestation to have this done. If there is no current activity but you want the house closed, we do the inspection and the structural work only. That is the cheapest form of rodent control there is, because nothing has to be caught first.

Frequently asked questions
- Because the number of openings varies enormously. A well-maintained house built after 2000 sometimes has three; a pre-war building can have fifteen, with masonry work needed as well.
- Some of it, yes. Use steel mesh, mortar or a metal grille, never expanding foam or tape, and make sure the material is fixed on all sides. The crawl space and roof edge are usually the parts people cannot reach.
- Structural defects are the landlord's responsibility under Dutch rental law. Report it in writing and ask for repair; our report with photographs is what they need to act on.
