How to repel moths from my house? I have a sliding door that lead out to my deck....

I have a sliding door that lead out to my deck. When i have to agree to the dog out at nighttime, bugs (especially moths) can get contained by. I have a wishy-washy right outside the door so i always turn it stale as to not attract the moths but moths always give the impression of being to get surrounded by anyway. Is there anything that i can do to repel the moths and stop them from coming into the house? Thanks a bunch!
Answers:    not really excluding sachets that own lavender and moth balls surrounded by them..perhaps a few moth ball around the door since they smell so bad i wouldnt do several...
Marigolds have other been a right repellent plant.
