Pest Control under who's responsibility? Landlord or Tenants'?

[Mike H.]

Dear BP Family,  

Here comes another encounter of LL/Tenant question for the experienced Landlords out there.  I've received a request to provide professional pest control service from tenant to help eliminate pest issue at the rental property.  I have done a research, it appears the law does (DFW, Texas area) require LL to provide a healthy, well contained property for tenants.  And some would consider pest control as part of it.  My question is, what if the tenant(s) does not have a good hygiene hobbit and results a pest infected property, would LLs still be responsible for this type of issues?

Thank you in advance!!
