Rats: no resident waiting for it. Yet they also walk around in our city. Of course you don’t want those animals in your house. Do you have to contact the municipality of The Hague if you are bothered by rats? Or do you have to solve it yourself? And how do you prevent it from bothering you?

There are no reliable figures about the number of rats in the Netherlands. What is clear is that the number of rats in our country is increasing. This is apparent from the number of reports about rats. In Amsterdam, this number has more than doubled. According to the GGD, this is partly due to the corona crisis. At that time, more waste was produced at home and more people noticed the rat problem.

This creates a rat infestation

Rats often crawl into a home through broken sewers and cracks or chinks in the exterior walls. To prevent a rat infestation in the house, it is therefore important to close all unwanted openings in the outer walls. You do this with steel wool and/or fine mesh. Do you want to prevent a rat infestation in your home? You can buy fine-mesh gauze and steel wool at the hardware store.

Rat control

But please note: if If you already have rats in your house, you should not do this. Then turn on the rat control. In The Hague, for example, you call in The Fighting Brigade. The pest control service can tell you what is best for you in your situation.

The costs

Are you renting a house? In that case, the costs for rat control in most cases fall under minor repair work that is for the account of the tenant. If it concerns a structural problem or if the vermin is caused by other tenants, the costs are in in some cases for the account of the landlord. An overview can be found at Rijksoverheid.

The price for rat control starts at approximately 90 euros. Depending on the size of the problem, the price increases. How quickly the rat problem is solved after that depends on how big the problem is and how the problem is tackled.

Outside on the street

A rat infestation can also occur in outdoor areas, for example in a park or on the street. You often find them in places where people leave food residues. It is therefore not a good idea to feed the ducks old bread, because rats are attracted to the leftover bread. Bird food and rabbit food is also a favorite. It is therefore important to always keep pet food well closed.

How do you tell the difference between rats and mice?

Were you shocked when a beast swept through your house? ran, but did you find it difficult to tell if it was a rat or a mouse? It is easy to find out whether you are dealing with mice or rats.

A mouse has larger ears and a longer tail in relation to the body. A rat has larger legs and a larger head in relation to the body. The brown rat (most common species in the Netherlands) has a thicker body and shorter tail.

Droppings and food scraps

You can also see the difference in the food scraps. Mice nibble on food, while a rat ‘cuts’ food with its teeth. You can see the difference in the food left behind by the rat.

The droppings of brown rats are dark brown in color and are wide in the middle and narrow at the ends. They are about ten to twenty millimeters long. The droppings of mice are about three to eight millimeters long, black in color and granular in shape. Rats’ droppings are often clustered together, while mice leave them scattered everywhere.
