Some small birds (finches?) are trying to build a nest in one of our 2 front porch lights. They can access the inside from down below openings. This has been going on for like, a week. Each day, there is a mess on our front porch of twigs, sticks that they are dropping. Each day I am having to clear our the few twigs that they manage to get IN to the light. This is a fire hazard, I use those lights many nights a week for when my hub works late. Where we live is full of trees and other homes! Why so persistent to nest at ours? We have acres of woods in our back yard. But, we also have a 'bird feeding station' in our back yard, that's always stocked with bird feed/sunflower seeds, where they likely eat daily. So, they must want to stay close to the food. Lol. Anyone have any simple deterrents? I guess I could cram paper towels up in the openings, but that's also a fire hazard. Would just leaving the lights ON 24/7 until they give up, help? Or, would they not care about the heat emanating from the 5 small candelabra type bulbs? Thanks!
