House isn't that old, probably 1970 so it's not as if it's a thatched cottage circa 1800. There are cobwebs on all ceilings, upper walls, light fightings, any corner or crevice. I use an extendable duster thing every few weeks and even started hoovering the walls
but the buggers come back with a vengeance within a week. I never, ever see cobwebs in anyone else's house, so what is it about mine? Windows are regularly opened to let in fresh air and I don't have the heating on high. Strangely I don't have a lot of dust.
