Anyone who goes fishing, carries out river fly monitoring, does river habitat works, or indeed is involved in any other water-based activities, should be aware of the risks of transferring diseases and invasive non-native species (INNS) on clothing and equipment.
The basic advice is to ‘check, clean and dry’ all equipment and clothing. For a very effective, simple solution, the check, clean, dry protocol can be augmented with immersion of equipment in hot water (45C) for a period of 15 minutes (Anderson et al. 2015). This approach will even cope with kit like felt-soled wading boots which are notoriously difficult to clean and dry effectively.
