Use approved agents
Mosquito and tick repellent must be approved by the Swedish Chemicals Agency. Approved agents always have a four-digit registration number and are divided into three authorisation classes. Products marked Class 3 may be used by the general public. In the Pesticides Register ( in Swedish only) External link., you can check the registration number and see if the product is approved, what class it belongs to and find other important information.
Natural is not the same as harmless
Some agents that are not approved by the Swedish Chemicals Agency are based on so-called “natural substances”, which in some cases means that they are based on essential, volatile oils. But natural does not necessarily mean harmless, and the oils can cause harm, such as hypersensitivity or allergic reactions. Make sure that the chemical pesticides you buy are approved by the Swedish Chemicals Agency.
Your right to information
If you buy a tick or mosquito repellent on the internet, you always have the right to receive all hazard information about the product before you make the purchase. Keep in mind that other countries may have other regulations, but any agents that are to be used in Sweden must follow Swedish regulations.
The Swedish Chemicals Agency finds no reason to advise against the use of approved mosquito and tick repellents by pregnant women when other methods do not provide sufficient protection.
In case of an accident
