If you're noticing an unpleasant odor in your stairwell, a likely cause could be a pest problem. Rodents, insects, or other pests can bring a variety of smells associated with their presence. For example, rodents often leave behind droppings that can create a musty or sour scent. Additionally, if they die within the walls or hidden spaces, the decomposing bodies emit a strong, foul odor.
In addition to pests, there are several other reasons for odors in stairwells:
If you're in Nashua, New Hampshire, being aware of these potential sources can help you identify the cause of the odor more quickly. Understanding these issues enables you to take necessary steps for your health and comfort.

Pest droppings, especially from rodents, often create a musty, sour, or ammonia‑like smell that lingers in enclosed areas such as stairwells.
If a pest dies inside walls, vents, or hidden spaces, the decomposing body releases a strong, unmistakably foul odor that worsens over time.
Unpleasant smells may be paired with signs like droppings, nesting materials, or insect trails, indicating that pests are actively present and causing the odor.
If you suspect pests may be causing odors in your stairwell, here are steps you can take to resolve the issue:
Inspect the Area for Signs of Pests
Start by looking for any signs of pests. Check for droppings, gnaw marks, or nests. Rodent droppings are small and dark, while insect droppings can vary in size and shape depending on the bug. Look for any sounds or movement in walls or ceilings, as this might indicate an infestation.
Seal Entry Points
Once you identify signs of pests, it’s important to prevent them from entering your home. Inspect walls, windows, and doors for small cracks or openings. Seal these with caulk or weather stripping. This will help keep pests out and reduce the likelihood of future infestations.
Clean and Remove Attractants
Cleansing and removing anything that might attract pests is crucial. Keep the area clean by regularly sweeping and mopping your stairwell. Dispose of any trash in sealed containers and avoid leaving food items exposed. This discourages pests from returning.
Use Traps and Baits
If you notice a continued presence of pests, setting traps is an effective method. Use snap traps for rodents and sticky traps for insects. Place these in areas where you have seen signs of activity. Additionally, you can use bait stations that attract pests to poison them, but be sure to use them safely and keep them away from pets and children.
Consider Professional Pest Control
If the problem persists, it might be time to call in a professional pest control service. Pest control experts have access to stronger treatments and are trained to handle infestations safely and effectively. They can provide long-term solutions and advice on preventing future issues.
Follow Up and Monitor
After taking steps to eliminate pests, keep an eye on the area to ensure that the problem is resolved. Monitor for any new signs of activity and continue maintaining cleanliness. Regular checks can help catch new issues before they become bigger problems.
By following these steps, you can effectively manage and eliminate pest problems, reducing unpleasant odors and helping ensure a clean, comfortable environment in your stairwell.
