Your Rights Dealing With Apartment Pests in Wyoming

Health & Safety Standards Wyoming published: June 21, 2025 Flag of Wyoming

If you're living in an apartment in Wyoming and discover a pest infestation, it's important to know your legal rights, your landlord's responsibilities, and the correct steps to solve the issue. Under Wyoming law, both you and your landlord share responsibilities for safe, habitable housing — and that includes keeping your home free from infestations like bedbugs, roaches, mice, or other pests.

Understanding Health & Safety Standards in Wyoming Rentals

Wyoming's residential tenancy law requires landlords to provide safe, sanitary, and habitable housing. This includes maintaining structures that are free of pest infestations when you move in and responding to serious pest problems during your lease.[1]

What Is Considered a Pest Infestation?

A pest infestation occurs when insects, rodents, or other animals become numerous enough in your rental to affect your safety, health, or ability to use your apartment normally. Common pests include:

  • Bedbugs
  • Roaches
  • Mice and rats
  • Ants
  • Other invasive insects

Wyoming law doesn't specify exact pest types but focuses on the effect on your health and habitation.

Your Landlord’s Responsibilities for Pest Control

Landlords must keep rental units in habitable condition, which includes repairing, cleaning, and treating pest infestations not caused by tenant behavior. If pests are present when you move in, or become a problem despite your normal cleanliness, your landlord is generally responsible for resolving the issue.[1]

  • Timely response to written repair requests
  • Providing notice before entering for inspections or extermination
  • Ensuring pest treatment meets state health standards

Your Role as a Tenant

As a renter, you must keep the apartment reasonably clean and avoid causing pest issues through actions such as improper food storage or lack of regular trash disposal.[1]

If you spot pests, always notify your landlord in writing and keep copies of your correspondence. Your written notice creates a record that helps protect your rights.

Steps to Take If You Find an Infestation

Addressing a pest problem promptly is key for both your health and your rights as a renter. Here’s what to do:

  • Document the problem: Take photos, keep samples if possible, and keep a log of when and where you see pests.
  • Notify your landlord in writing: Use written methods (email or letter) to formally report the infestation. State what you found and request treatment.
  • Request repairs using official forms:
    While Wyoming does not have a specific state form for pest complaints, it’s best to use a “Notice to Landlord for Repairs.” Wyoming Legal Aid provides guidance on preparing such a notice: notice guidance from Wyoming Legal Aid.
  • Allow reasonable time: The law gives your landlord a reasonable period to address repairs, usually depending on the severity of the pest problem (often up to a few days for urgent issues).
  • Follow up: If you get no response or repairs, consider contacting the local health department or seeking legal help.

What If My Landlord Doesn’t Fix the Problem?

If the pest issue makes your apartment truly unlivable and your landlord ignores your written notice, you may be entitled to:

  • File a complaint with your local city or county housing authority
  • Request a rent reduction or make repairs and deduct the cost (with strict compliance with the Wyoming Residential Rental Property Act)
  • Seek legal action or mediation through your local circuit or district court

Note: Wyoming does not have a separate residential tenancy board; tenant disputes are resolved in County or District Court. Find official court information on the Wyoming Judicial Branch website.

What Forms Do Wyoming Tenants Use For Pest Issues?

  • Notice to Landlord for Repairs (no official form number): Use this written notice to formally request pest treatment or repairs.
    Example: If you find mice in your kitchen, write a short letter describing what you found, when you found it, and that you want it treated. Keep a copy and send another to your landlord.

If your situation escalates (for example, your landlord seeks eviction while you have ongoing repair disputes), formal court forms may be required. These can be found at the Wyoming Judicial Branch Forms page.
