Fresh cab
X2 Fresh cab works best in confined spaces. I put them in the outside storage compartments and in the cupboards where the water and/or electrical lines come in. Works for us so far. Our trailer sits on a seasonal site and our friends on the next site found the dyer sheets torn up and mixed with leaves to make a nest in a drawer under the sink on Saturday. Also as others have said plug all holes that give them access. I use stainless steel wool and great stuff to seal up what I can see.
