Hi Mike,
I think it will also depend on what kind of bugs you are trying to repel. Planting that many plants nearby (particularly flowering plants) will inevitably attract pollinators. The dirt below the plants will be prime living space for slugs, beetles,
ants, and the like. Living in Maine, I totally understand the desire to keep mosquitos and black flies out of the house. However, trying to plant a small garden and keep out ALL bugs, is a little like trying to plant a forest, but trying to keep out all squirrels,
deer, racoons, birds, etc. Its not going to work very well. This planet was designed for all sorts of life to be mixed up together.
My suggestion would be to build some outdoor spaces with ceilings and arbors and the like. This way you get some of the "inside" outside, but you won't have to open your house up to bugs coming in.
