🕳️ Why Mole Activity Is Suddenly High in UK Gardens This Autumn
If your garden was mole-free earlier this year but fresh molehills are now appearing, you’re not alone. Across the UK, pest control professionals are seeing a sharp rise in mole activity this autumn. Here’s why it’s happening — and what you can do about it.
🌧️ 1. Rain & Moisture Bring Earthworms (and Moles) to the Surface
After the extremely dry spring and summer of 2025, autumn rain has softened the soil. Earthworms — the mole’s main food source — move closer to the surface in moist, oxygen-rich ground.
Naturally, the moles follow. The result is new surface tunnels and fresh molehills, often appearing overnight.
🐾 2. Young Moles Are Leaving Home
Moles born in spring are now fully grown and looking for their own territories. These young moles are pushed out by their parents and start exploring nearby gardens, fields, and verges.
If your lawn was treated earlier in the year, these newcomers are likely responsible for the renewed activity — not a return of the old residents. Action is immediately before they become an issue.
🍂 3. Autumn Feeding Frenzy
Before winter sets in, moles feed heavily to build fat reserves. The abundance of worms in autumn makes this the ideal time for them to hunt. Their increased surface activity makes them far more visible to homeowners — and far more destructive to lawns.
🌡️ 4. Mild Temperatures Keep Them Active
A warm, damp autumn means moles don’t need to retreat deep underground yet.
As long as the soil remains soft and rich in worms, they’ll stay close to the surface, leaving visible runs and hills.
🧭 5. Old Runs Collapse, Territories Shift
Soil naturally settles and compacts over time, especially after summer dryness.
As old tunnels collapse or food zones shift, moles are forced to reopen or rebuild runs — sometimes right where you thought the problem had been solved.
✅ What You Can Do
If mole activity has reappeared, it’s not a reflection of poor control — it’s part of a natural seasonal cycle.
Professional mole control is still the most reliable way to remove new arrivals before they cause major damage.
