the lower back and one side of our house has good size spider webs. I clear them away but they start over again. My friend says I must have bugs?

i have not noticed any ants, etc inside. Is this something to be concerned about?

I definitely am not an expert in this area, but I've never seen a spiderweb focus on non-airborne insects. They almost always focus on things like flies, mosquitoes, etc.

Depending entirely on the species of spider, they normally put up spiderwebs in an area that generally does not get a lot of wind, but instead in an area where a small flying insect would be more likely to travel (an area that has less breeze and an easier area of passage). That can be around houses, between shielded trees, etc.

I can't say what would cause it, other than to say that maybe the area attracts mosquitoes or flies. Is this where the trashcans sit, or is there a pond or water stagnation in the area? If so, that might be draw for the area...
