This is our maximum strength mosquito repellent formulated for malarial areas, following the withdrawal of Trek 100 from the range due the EU Biocidal Products Regulations. Trek 50 (formerly Repel 55) is the insect repellent of choice for long-haul travellers, adventurers and explorers.

It is ideal for travel in areas of tropical and sub-tropical Central and South America, sub-Saharan Africa, India and Pakistan and South-East Asia.
