01

Appearance

Bacteria and most microorganisms are not visible without magnification; their presence requires appropriate sampling and testing.

02

Behavior

Growth and survival depend on moisture, nutrients, temperature, surface condition and the organism involved.

03

Diet & habits

Microorganisms use available organic or inorganic nutrients in their environment.

04

Reproduction

Many bacteria multiply by cell division, sometimes rapidly when conditions are favourable.

05

Signs of an infestation

There may be no visible sign. Odour, slime, staining or repeated hygiene failures can indicate a need for investigation.

06

Health & property significance

Some are harmless or beneficial while others can cause illness or spoilage. Testing and treatment must match the specific risk.

Prevention

Reduce the conditions that help pests thrive.

Confirm the organism before selecting control measures
Remove food, water and shelter where practical
Seal or manage access points and harbourage
Use monitoring and a site-specific IPM programme
