I have been using UV light for years to trap insects and look for other invertebrates such as scorpions. I recently decided to use UV light to look for pests in the garden. When scanning the tomato plants they lit up like Christmas trees with tomato hornworms glowing a bright blue-green in the light. I was able to remove over 20 of them in five minutes; because of the dense growth of the plants none of these were easily visible in daylight.

Great idea! I didn't know the hornworms would glow. I do use the light for scorpion hunting.

This is an awesome thing to know!!! Thank you Paul!
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others.

Does anyone know what other common garden creatures would glow?
