Rodents in Autumn – Why Infestations Rise After Harvest
As the nights draw in and the weather turns cooler, many homes and businesses start to notice an unwelcome problem – increased rodent activity. Autumn is one of the busiest times of year for pest controllers, and there’s a very good reason for it.
🌾 Harvest Season & Changing Habits
In rural and semi-rural areas, fields are filled with crops throughout the summer, providing an abundant food source for rats and mice. When harvest comes, this supply suddenly disappears. With less food in the fields and cooler weather setting in, rodents are forced to look elsewhere for warmth and sustenance.
Unfortunately, homes, sheds, garages, and business premises offer exactly what they need – food, shelter, and warmth.
🏠 Why Rodents Move Indoors
There are three main reasons rodents invade properties in autumn:
Shelter from the weather – Colder nights and wetter days drive rodents to find dry, warm places.
Food sources – Kitchens, bins, pet food, bird seed, and stored grain are easy targets.
Breeding opportunities – Rats and mice breed rapidly. A single pair can multiply into dozens over a short period if not controlled.
🔎 Signs of an Autumn Rodent Infestation
If you suspect activity, look out for:
Droppings (small black rice-shaped for mice, larger spindle-shaped for rats)
Gnaw marks on wood, wires, or packaging
Scratching noises in walls, lofts, or under floors
Grease marks along skirting boards or pipes
Nesting material (shredded paper, fabric, insulation)
🚫 Why You Should Act Quickly
Rodents are not just a nuisance – they can cause:
Health risks by spreading diseases such as salmonella and leptospirosis.
Structural damage by gnawing wires, pipes, and insulation.
Contamination of food and storage areas.
Leaving the problem unchecked will only make it worse, especially during autumn when rodents are actively seeking out new nesting sites.
✅ How to Protect Your Property This Autumn
Seal up gaps and holes around doors, pipes, and air bricks.
Keep bins secure and food stored in sealed containers.
Don’t leave pet food or bird seed out overnight.
Book a professional inspection if you’ve noticed signs of activity.
