Are you tring to get rid of it? What do you need help with?
If it’s getting rid of that movement, my first thought was that would be a good place for a v3 in color night vision due to the outdoor light on the right. That would turn off the onboard IR lights because it appears that those are the attractant. The bugs/insects will always be there, especially with the woods and pond nearby, just have to find ways to not have them illuminated so much.
