Does Your Rangehood Have Poor Suction? Rodents Could Be the Culprit
A rangehood is meant to keep your kitchen fresh by removing smoke, steam, and odours. But what happens when suction suddenly drops off? While dirty filters and weak motors are common causes, there’s another issue many homeowners don’t think about: rodents damaging your ducting.

🔹 How Rodents Affect Rangehood Suction
Rodents such as rats and mice often seek warmth and shelter in roof cavities and wall spaces. Unfortunately, rangehood ducting can be an easy target:
- Chewing Through Ducting: Rodents gnaw at flexible ducting, creating holes where air escapes.
- Blockages: Nesting material or droppings inside ducting can restrict airflow.
- Leaks in the System: Even small tears reduce suction, meaning smoke and steam don’t reach the outside vent.
The result? Poor rangehood performance, lingering odours, grease build-up, and frustration in the kitchen.
🔹 The Solution: Rodent-Proof Ducting
The best way to solve and prevent this problem is by upgrading to rodent-proof ducting. Unlike cheap flexible ducts that rodents can chew through easily, rodent-proof options are made from rigid metal or heavy-duty materials designed to withstand damage.
Benefits of rodent-proof ducting:
- Maintains strong suction and airflow.
- Stops rodents from entering or nesting in the system.
- Reduces long-term maintenance and repair costs.
- Ensures your rangehood operates at maximum efficiency.
