The landscape around Leiden and its effect
Every place has its own reason for rodent activity, and in Leiden it starts outside the house. Historic buildings have voids in places modern construction does not: behind panelling, under timber floors, in the space between an old and a newer wall. Combined with the moisture that older masonry holds, that makes a historic centre an environment where a population can settle quietly.
That is why proofing is part of the standard job in Leiden and not an optional extra. Alongside that, the river and its banks plays a part in what we find here.
Leiden falls under the municipality of Leiden in Zuid-Holland. We cover it on the same schedule as the surrounding places, including Katwijk, Alphen aan den Rijn and Wassenaar, so an extra visit rarely takes long to arrange.
What we look at first in Leiden
An inspection in Leiden runs a fixed route past the situations that occur here. In concrete terms:
- cellars that connect beneath adjoining buildings
- soft mortar and settled masonry with open joints
- timber floors and voids behind panelling
- the river bank and floodplain within walking distance
From your call to a solved problem
- 1
Survey
The whole building envelope: foundation, facade, thresholds, vents, roof edge and penetrations.
- 2
Prioritise
First the openings that are demonstrably in use, then the ones that pose a risk.
- 3
Carry out
Steel mesh, mortar, replacement vents and brush profile, neatly finished and rodent-proof.
- 4
Hand over
Photographs of the points dealt with and advice on the maintenance you can do yourself.
Safety decides the method here, not the other way round. In a household with children, dogs or cats we use mechanical control as standard: shielded traps inside tunnels, placed where only the target animal can reach them. Where we do use a product, it goes exclusively into a locked bait station that opens with a key.
For an emergency the practical sequence is this: on site the same day where possible, close off the acute room, set traps, and only at the second visit go through the rest of the house and the outside in full.
Price structure and conditions
We work with three clear levels. The first is the inspection with advice: that is free, including when it shows no treatment is needed. The second is a single treatment from 95 euros, for a contained problem such as mice in a kitchen. The third is control combined with proofing, where we solve the problem and close the building.
Concretely: inspection and quote free, single treatment from 95 euros, control plus proofing quoted per property. What is not included we say in advance, so nothing is a surprise afterwards.
Doing it yourself versus having it done
- DIY traps work for a single mouse, not for a group
- Poison placed wrongly leaves carcasses where you cannot reach them
- Without proofing the problem returns within a few months
- Repairing pipes or insulation costs many times a treatment

Prevention indoors and outdoors
The second layer is structural: if there is nothing to get in through, the problem stays outside. Walk around the house once and look at knee height and below, because nine times out of ten that is where the opening is. Think of the gas pipe penetration, the gap under a threshold, a broken air brick and the join at the downpipe.
This is the part you have the most influence over yourself. A treatment that is not combined with clearing up holds for a few months at best.
What to do in the first week
- Remove food sources indoors and outdoors straight away
- Check the building envelope at knee height and below
- Mark a trace and look again two days later
- Have it checked while it is still a handful of animals
The signs we find in homes in Leiden
Damp and rodents belong together, and that connection is often missed. Rats need to drink daily and settle by preference where water is available: a leaking pipe, a blocked downpipe, a wet crawl space or an old disused drain. Where it is dry, they rarely stay long.
A second early signal is food disappearing faster than it should. If more goes out of the bowl than your pet eats, or if you find biscuits in an odd place behind a cupboard, something is eating along. Rodents carry food back to the nest, and those displaced pieces often point fairly precisely in the right direction.
Search the edges, not the middle
- Follow skirting boards, cable ducts and pipes; that is where they run
- Hold the torch low and at an angle so grease marks show up
- Look behind and under appliances that are rarely moved
- Watch for fine footprints and a tail drag mark in dust
Rats and mice in Leiden: common questions
- Yes. We will drive to Leiden for a single mouse behind a skirting board. With a small problem the work is done in one or two visits, which is the cheapest outcome for both sides.
- Yes, all of Leiden and the rest of the municipality of Leiden, plus the surrounding villages and districts in Zuid-Holland.
- Ask for the Dutch certificate for rodent management. Without it no rodenticide may be used outdoors. Our technicians work to the IPM rules.
- A cat will catch the occasional mouse, but it cannot reach an established population in the cavity wall or under the floor. The opening they come in through also stays exactly where it was.
- We remove it in full, together with the nesting material. Leaving a nest and catching only the adults causes an odour problem and solves nothing.
