I had a few questions about black lights. How long does an arachnid need to be exposed to it to have harmful effects? What are some of the best flashlight black lights you've used? Would they work for field herping or would I have to get a filter to remove visible light? What are some of the best wavelengths of black lights to show up the most and be the most distinctive? Thank you in advance.
