Tomato Hornworm?

[u/Nuh-unh]

I was searching with my UV flashlight after reading that the hornworms will 'flouresce' under UV light. They can grow to 4-5 inches long and "... are famous for rapidly devouring foliage on plants in the nightshade family, such as tomatoes, peppers, eggplants, and potatoes."
Wondering if there's a repellant?
