I used to paint houses during the summer, and at the end of the day, the other painters and I would always tell the customers not to turn on their outside lights at night because lights would attract all sorts of flying insects — june bugs, moths, mosquitoes — and they would get stuck in the still-wet paint. Inevitably, someone would flick on the outside lights. Then I would have to scrape the caught critters off the new finish coat.
To remedy the situation, I took to unscrewing the outside bulbs that were anywhere near the house. Bugs still are attracted to light corning from the windows at night, but not having any illuminated bulbs on the outside of the house helps to minimize the condition.
