Autumn Rodent Surge: The Ultimate Guide

rat infestation, rodent proofing autumn, pest problem
October 19, 2025

As the seasons change and temperatures fall, London often experiences a noticeable surge in rodent activity. At Obsidian Environmental Services, our qualified technicians have seen this pattern for decades. As autumn sets in, rats and mice begin seeking warmth, food, and shelter inside homes and commercial properties.

Why Rodents Become More Active in Autumn

Autumn brings several environmental changes that directly influence rodent behaviour.

  • Cooler weather pushes rodents indoors in search of heat and protection from the elements.
  • Food shortages occur as natural supplies dwindle; crops are harvested, plants die back, and less waste is left outdoors.
  • Loss of leafy shelter exposes rodents that typically nest in overgrown areas, forcing them to move closer to buildings and other covered spaces.

Together, these factors create the perfect storm for increased rodent movement and infestations across London.

The Impact on Homes and Businesses

As rodents move indoors, activity spikes in both residential and commercial environments. You may start to hear scratching noises in walls or loft spaces, find droppings in cupboards or storage areas, or notice gnaw marks around skirting boards and cables. For businesses, especially those in hospitality or food service, this can quickly escalate into hygiene risks and potential reputational damage if left unchecked.

Simple Steps to Deter Rodents This Autumn

While professional proofing is the most effective long-term solution, there are several quick actions you can take to make your property less inviting to rodents:

  • Keep bin stores clean and sealed to prevent easy food access.
  • Dispose of food waste responsibly and avoid leaving pet food or general waste out in the open overnight.
  • Inspect entry points; look for gaps under doors, cracks in brickwork, or damaged vents.
  • Declutter outdoor areas to reduce potential nesting sites.

Common Signs of Rodent Activity

If you’re unsure whether rodents have entered your property, look out for these tell-tale signs:

  • Small, dark droppings around walls, corners, or cupboards.
  • Gnaw marks on skirting, packaging, or cables.
  • Foul or musky odours, particularly in enclosed spaces.
  • Scurrying sounds at night within walls, ceilings, or under floors. Early identification can make all the difference in preventing a small problem from becoming a serious infestation.

    Amazing service by Daren. Did the checks very detailed and communicated to the team. Asked about the issues and how he can assist us. Also on his previous visit he went out of his way and helped with the door issue we had as one of our team members was stuck in the toilet. He opened the door for us and let the team member out. Great service
