We have moths at the telescopes on Mt. Graham in eastern Arizona. Lots of them.
The solution was to make the Mothinator 2000 XL. This is a 50 gallon garbage bin with the UV light frame from a big bug zapper mounted on the lid, but without the zapper energized. Instead, there’s a big 8" fan under the UV light that sucks the moths into the garbage bin.
The garbage bin fills to half-full after a month of service in the warmer months.
