Multiple outlets report that some Fitbit Air owners are discovering their trackers can be damaged after contact with bug spray. Android Authority describes a user account in which the wearable was affected following exposure to insect repellent. TechRadar similarly highlights a scenario where a Fitbit Air is reportedly ruined after being sprayed with bug spray, with commenters and the publication noting the outcome as a warning. Phandroid and MobileSyrup also raise concerns that insect repellent and certain bug-spray ingredients can harm the device. While the reports focus on user experiences rather than laboratory testing, they consistently advise against applying bug spray directly to the tracker and treating it as incompatible with insect repellents. The coverage centers on the idea that chemical components in bug spray may damage the wearable’s materials or outer coating, leading to malfunction or physical deterioration. Readers are directed to avoid spraying the device and to consider using repellent on clothing or other approved methods instead.
