In Idaho, landlords are generally responsible for keeping rental units habitable, which includes addressing pest infestations that existed before move-in or that result from structural conditions (cracks, leaks, gaps). Tenants are typically responsible if their behavior (poor sanitation, untreated bed bug exposure from travel, etc.) introduced the infestation. The Idaho Residential Landlord and Tenant Act sets the framework, and most lease agreements clarify the split.
What Idaho law requires
Idaho’s habitability standard (Idaho Code §6-320) requires landlords to maintain rental property in safe and sanitary condition. Active pest infestations that affect habitability, bed bugs, rodents, cockroaches, typically fall under the landlord’s obligation unless the lease explicitly assigns it to the tenant AND the tenant caused the infestation.
Practical splits in Idaho rentals
- Bed bugs. Usually landlord responsibility unless the tenant introduced them (travel exposure, secondhand furniture).
- Rodents. Landlord responsibility if entry points are structural; tenant if pet food / open trash drives it.
- Ants, spiders, wasps. Varies by lease; quarterly pest control is often a landlord-provided amenity at multi-unit properties.
- Recurring quarterly pest control. Typically landlord-provided at apartment complexes; varies for single-family rentals.
If you’re a tenant in Boise
Document the issue (photos + dates), notify the landlord in writing, and reference the habitability standard. If the landlord doesn’t respond, Idaho law allows tenants to use rent-withholding remedies subject to specific procedure. Consult the Idaho Attorney General’s Office consumer protection division for current procedural guidance.
