How do you explain the obvious to a tenant..you're not clean...

[Maya Torres]

I have tenants who are not the cleanest. Plain and simple. Wife says she has a moth problem and asks me if I have the same problem (I don't) because I live next door and asks if she can get it looked at. Makes me feel like my unit is the problem as a landlord. How do you explain it to the tenants that if they kept their house clean they probably wouldn't be having all of these issues? I know it's not my duplex because I live in it and I don't have an insect problem. Insects don't discriminate. Suggestions please.

@Karl B. Gross! Lol. I actually did a google search because I had no idea what causes a moth problem and I text the tenant a run down of what she should do but pamphlets and actual instructions are way better. Great idea! Thanks so much.
