My in-laws are in Arizona where there are scorpions. I’m giving them a powerful blacklight flashlight so we can go look for them when it gets dark out.
Be aware that powerful UV flashlights (especially the no-name Chinese ones) can also damage your eyes quickly without you noticing. Better ones will come with protective glasses.
To be clear UV flashlights are NOT the same as blacklight flashlights. However I totally agree if you are getting a UV light source for some reason, eye and possibly skin protection is a fantastic idea
