Overview
- Germany’s mild winter and northward species shifts have driven record tick numbers with up to 40 percent carrying Borrelia bacteria
- The “Invertiert” filter in a phone’s magnifier app swaps colors to make blood-sucking ticks stand out against hair or skin
- iOS users enable the filter by opening the Magnifier app, tapping the gear icon, adding the Filter control and selecting Inverted
- Android owners can set up a Magnifier shortcut in settings to access the inverted view, while Google Pixel 4a (5G) and older models require third-party apps
- Early spotting of tiny nymph ticks supports prompt removal and helps prevent tick-borne diseases like Borreliosis and FSME
