If you have gone looking for rat poison in the Netherlands and come back empty handed, you have not missed a shelf. Since 2023, rodenticide may only be used outdoors by professionals who hold the relevant certification, and only as part of a documented Integrated Pest Management approach. For anyone who has moved here from a country where a box of bait sits next to the mousetraps in the supermarket, that is a genuine surprise. This article explains what changed, why, and what the alternative actually is.

What the rules on rat poison in the Netherlands say

The short version: the substances used to kill rats are anticoagulants, they persist, and they move through the food chain. The Dutch authorisation regime responded by tightening who may use them and under what conditions.

In practice that means three things for a household:

  • You cannot buy professional rodenticide as a private individual.
  • A professional may not simply put down bait either. Poison is a last step, permitted only when the cause has been addressed first and the treatment is documented.
  • The certification is real and checkable. A technician working outdoors with rodenticide is expected to hold it.

Glue traps deserve a separate mention. They are still sold in places, they are indiscriminate about what they catch, and they do nothing at all about how the animals are getting in. They are not a serious tool for a rat problem.

Why the ban is not the obstacle it looks like

The instinct when you have rats is that you need something that kills them, fast. The reason the rules push against that is not squeamishness; it is that poison on its own has a poor track record.

A rat population in a Dutch house is there because something is feeding it and something is letting it in. Kill the animals without changing either, and you have bought a few weeks. The route into the crawl space is still open, the damaged drain is still damaged, and the next animals along the street find the same vacancy.

There is also the problem of where poisoned rats die. In a crawl space or a cavity wall you cannot reach, that turns a rodent problem into a smell you live with for a month.

What Integrated Pest Management means in practice

IPM sounds like jargon and is actually just an order of operations:

  1. Inspect. Establish what you have, how many, and where they are living rather than where they are being heard.
  2. Identify the cause. Food source, water, harbourage, and the specific gaps being used.
  3. Take it away. Waste management, the bird feeder, the compost heap, the open bin store.
  4. Close the routes in. Ventilation gratings, pipe penetrations, drainage defects, gaps under doors.
  5. Only then treat, with trapping or, where it is genuinely justified, monitored bait under certification.
  6. Check. A follow-up visit that confirms the activity stopped rather than moved next door.

Steps three and four are the ones that decide whether the problem comes back. That is why professional rat control here begins with an inspection rather than with bait, and why the inspection is free: without it the rest is guesswork.

What you can legally do yourself

Quite a lot, and it is the part that lasts.

  • Snap traps for mice remain available to private individuals and are effective indoors when they are placed properly, against a wall, at right angles to the run, where droppings are actually being found.
  • Remove the food. Dry goods in hard containers, no pet food left down overnight, no open food waste, no spilled birdseed under a feeder.
  • Close the gaps you can reach. A mouse needs six or seven millimetres, a young rat about two and a half centimetres. Steel wool packed firmly into a gap and sealed over holds; foam alone does not.
  • Keep the perimeter clear. Dense planting straight against the foundation and firewood stacked on the wall both give cover right where you least want it.

What you should not do is import rodenticide from abroad or buy something advertised online as professional grade. Beyond the legal problem, you would be applying the least effective step of the process without any of the ones that make it work.

When to call someone in

Rats rather than mice, any activity in a crawl space, gnawed cabling, or a problem that has come back after you thought you had dealt with it: those are all reasons to have it looked at properly. In a block of flats it is worth doing early, because a shared building means shared shafts and a population that moves between units.

Longer term, the work that keeps a house clear is proofing and prevention: rodent-proof ventilation gratings, sealed pipe penetrations, sound drainage. It is unglamorous and it is the whole game.

Frequently asked questions

Is it illegal for me to use rat poison in my own home?

Professional rodenticide is restricted to certified users working within a documented Integrated Pest Management approach, so it is not something a household can lawfully buy and apply here. Snap traps for mice are a different matter and remain available to private individuals. If you are unsure about a specific product, that uncertainty is itself a good reason to have a certified technician look at the problem.

My neighbour has poison they brought back from abroad. Should I use some?

No. Aside from the legal position, you would be putting an unlabelled anticoagulant into a house where children, pets and wildlife can reach it, without knowing the active ingredient or the concentration. It also does nothing about the gap the rats are using, which is the part that decides whether they come back.

If poison is a last resort, what happens on a normal job?

Most of the work is inspection, removing what is feeding the population and closing the ways in, combined with trapping and monitored control points. Bait is used only where it is genuinely justified, always documented, and always alongside the proofing rather than instead of it. A follow-up check confirms the activity has stopped.
