Wingless, laterally flattened, dark insects with powerful hind legs. Adults are usually 1.5–4 mm long.

Adults live on hosts and jump readily. Eggs and immature stages accumulate in bedding, carpets and sheltered floor edges.

Adults feed on blood; larvae consume organic debris including dried blood shed by adults.

Eggs fall from the host into the environment. Larvae spin cocoons and adults emerge in response to heat, vibration and carbon dioxide.

Bites around ankles, scratching pets, flea dirt, jumping adults and activity in pet sleeping areas.

Bites cause irritation and allergic reactions, and some fleas can transmit pathogens or tapeworms.

Prevention

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

Professional support

Arrange a site-specific assessment with PCAMB.
