Treatment against rats, mice, cockroaches and other pests effectively is difficult. Call in a qualified pest control officer if you are affected. Professional treatment means not only that it will be more effective but also that fewer quantities of poison will be used, thus reducing the risk of harm to other creatures and humans.

If you must use pesticides, only buy a product which is approved by the Swedish Chemicals Agency. Approved pesticides are always preceded by a four-digit registration number and are divided into three authorisation classes. Products with a Class 3 marking are for public use. The Pesticides Register allows you to check the registration number and see whether the pesticide is approved and to which class it belongs, and to find other important information. If you buy a product for treating pests on the Internet, you always have the right to receive all the hazard information on the product before completing the purchase. Bear in mind that other countries may have other rules, but that the product to be used in Sweden must comply with Swedish rules.

Note the danger symbols and read the information so that you can protect yourself and handle the product in a safe way.

Rats and mice

Pesticides for rats and mice may harm your health and affect other creatures. If you suspect that a child or someone else may have happened to ingest a rat poison, you must immediately contact the Swedish Poisons Information Centre to seek advice.

Mice can be treated in many cases in the form of a classic mousetrap since mice are less suspicious of traps than are rats. Treatment against rats is difficult. If you have problems with mice or rats, please do contact a professional pest control officer via your home insurance company or property owner. Professional treatment against rats means not only that it is more effective but also that it reduces the amount of rat poison and the risk of harm to other creatures.

Prevent the problems by sealing openings where mice and rats can enter the building. Check ventilation ducts, cellars, attics and cesspools. Mice only need to jump 7 mm to get in, while rats need approximately 20 mm. Clear away food leftovers and waste which attract rats and mice. This also applies to public places such as parks and recycling stations. Store food in the fridge or a container.


The Spanish forest slug (the killer snail) inflicts damage in gardens, flowerbeds and vegetable plots. There are several methods of getting rid of snails, such as chopping them up, using traps or spreading lime around the plants. Snails are sensitive to drought. Therefore avoid creating any damp places in the garden. You can find further information at Snigelakuten (the emergency snail treatment centre) on the Natural History Museum of Gothenburg website.


There has been a sharp rise in lice in Sweden. Their bite may cause allergic reactions in the form of itching and a certain amount of swelling on the skin. Lice multiply fast and spread easily from room to room on clothing or objects. Lice are very difficult to get rid of, and if you are affected you should call in a professional pest control officer.

Avoid bringing lice and other vermin home with you after your holiday, such as by storing your clothing in a closed suitcase at the hotel. Don't push your case under the hotel bed, and don't take pillows or other bedding with you that you will then take home again. If you suspect that you have got lice in your packing, it may be worth placing the clothing in the freezer for several days when you come home to try to kill them in that way.


Cockroaches enter our homes together with food items and imported products. They seek out warm and damp places where they find food, such as kitchens or bathrooms. Cockroaches can spread both bacteria and viruses. Cockroaches are one of the oldest types of insect in the world and are counted among those hardest to treat. Therefore call in a professional pest control officer if you are affected.
