Stop Fleas with a Monthly Squeeze

The weather is warmer up so the fleas are emergency after being dormant over winter. APPLY YOUR FLEA CONTROL NOW.

Not only can we supply you with great quality flea products that will work but we have the expertise to help you eliminate those nasty pests. In order to understand why your flea control is not working you need to have an understanding of the flea life cycle:

Adult Fleas

  • Only live on the 1 dog, cat, rabbit, or any other animal for the whole of their lifetime. Transmission of fleas directly from one animal to another via jumping is actually very rare.
  • If a flea lives long enough on the pet's skin it will lay eggs.
  • 1 flea can lay up to 6000 eggs in it's lifetime.


  • When an egg is laid it rolls off the animals coat and into the environment
  • As the animal walks around it is like a salt shaker with the eggs being the salt.
  • Eggs will be in highest concentration where the animal spends most of it's time.


  • Larval stages are mobile and can move around in the environment. They will move up to half a metre to find their ideal environment
  • The larvae feed on dead skin cells which are flaked into the environment.


  • Eventually the larvae spin a cocoon and become pupae.
  • This stage can remain dormant for long periods of time (6-12 months)
  • Once the environmental conditions are right (warmth and humidity), they ready themselves for hatching
  • The pupae can detect vibrations which indicate that a host is around. They then hatch and jump
  • Pupal stages are resistant to all chemicals. Spraying the environment generally will not kill pupae.

If you are seeing lots of fleas then generally you have a lot of eggs, larvae and pupae in the environment. It takes time for all of these stages to be killed (up to 3 months) and that is assuming that you don't have any ongoing sources of new contamination with eggs such as wandering cats, rats, rabbits or other wildlife.

The right product for your situation is also important but simply switching products will not solve your problem if you have not identified and corrected the environmental problem. If you are having trouble elminiating your fleas then speak to one of our friendly veterinary nurses who will be able to help you sort out your issue.
