No one likes to admit they have a flea problem but flea infestations are very common particularly in association

With cats and dogs. Flea eggs drop to the ground, onto the carpet, only hatching when the next ‘meal’ walks by.

In particular, problems arise following a return from holidays or in dwellings hat have not been occupied for a

Period of time. When fleas have not fed for some time they are likely to be less specific about their choice of host

And take a feed of human blood. Fleas are much more common than Bed Bugs. Three species are most likely to

Bite humans in the UK, the Cat Flea (Ctenocephalides felis), the Bird Flea (Dasypsyllus gallinulae), and the Dog 

Flea (Ctenocephalides canis). The Dog Flea rarely bites humans, but will when no other host is available. Cat and

Bird fleas are more common than one might imagine. The unwarranted stigma attached to a flea infestation,

Prevents people telling others of the problem.

As the name suggests, cat fleas are normally associated with cats. Bird fleas are normally associated with birds

And are often a problem where birds are or have nested in some part of a building.




Ctenocephalides Elis


2–3mm long wingless ticks.

Flattened from side to side.

Have long legs enabling them to jump.


They have both genal and pronotal combs (ctenidia), differentiating them from most other fleas of domestic





Fleas pass through four stages: eggs, larva, pupa, adult. The eggs are small and white.

These stages combined vary from two weeks to eight months.

The adult flea is awakened by the detection of vibration of pet or human movement, pressure, heat, noise,

Or carbon dioxide for potential blood meals.


A cat flea cannot complete is life–cycle feeding only on human blood.


these fleas are often unable to determine whether a host is suitable until it has been bitten.

If it is deemed unsuitable, the flea soon drops off.

These fleas nest where the host is in its usual resting place, or example the cat basket.

This is where the young drop to mature.
