The scale insects comprise a large group of pest species.
For the lay person they can be classified into three groups:
- Hard (armoured) scale insects
- Soft scale insects
- Wax scale insects
Many scale insects have effective natural enemies, some of which are commercially available. Avoiding toxic pesticides and creating the right environment for beneficial insect to thrive are important to good scale management. Oil sprays can be an effective tool as a soft option for helping reduce scale insect populations.
