kittriana said:It could attract moths, but more likely somewhere was a lot of eggs laid in an outdoor plant that generated the caterpillars. You would have seen them (caterpillars) or noticed the damage to plant leaves as they grew and pupated. Any plant that is left outdoors can become a source of indoor swarms. You didn't show us the plant, but as to the other, insects are drawn to colors like a honeybee, red, orange, yellow and blue can attract all sorts of good and bad insects
