First, choose the mosquito repellent spray that suits your needs. Effective for up to 8 hours and for the whole family from the age of 1, Family mosquito repellent keeps European and tropical mosquitoes at bay. Tropical mosquito repellent is designed to repel even tiger mosquitoes in high-risk areas.
In the event of bites, Tricosteril offers two soothing treatments for rapid relief of itching: the After-Bite Roll-on and the Soothing Cream, with an immediate cooling effect. The two after-bite solutions will relieve the itching of the whole family, from birth onwards, from insect or plant bites.
With Tricosteril, take advantage of complete, family-friendly mosquito protection made in France, suitable for all needs and situations, whether you're traveling or at home.

Both Tricosteril anti-mosquito lotions offer 8-hour protection thanks to their high concentration of the repellent active ingredient IR3535®, renowned for its effectiveness. Both are suitable for the whole family from one year upwards. The main difference lies in the type of mosquitoes they are able to repel. The Family mosquito repellent protects you from European and tropical mosquitoes, while the Tropical mosquito repellent even protects you from tiger mosquitoes.
