A good method for keeping insects out of the house is to install insect screens at every window and door. It's almost 100% effective.

When it's dusty, all you have to do is just take them out to the bathroom and spray them with water. Leave them to dry before placing them back. I do this weekly.
I find these work so much better than the magnetic insect screens. These are stainless steel.
