We have nests behind our cement stairs. We are unable to move the stairs but there is a gap of about 1/2 inch between the stairs and outside wall.
The B&G duster would be a great tool for treating the gap around your stairs or similar cracks and crevices around the structure. Depending on the insect, you will want to choose an insecticide dust with some residual, such as Delta Dust, which is moisture resistant.
