Guardian Pro Flea & Tick Shampoo

​How long will it take for this product to begin to work?
The product should begin to kill fleas within 24-48 hours but may take up to 72 hours to reach its full effectiveness.

What is the difference between this product and oral flea products?

This flea product will kill fleas and ticks for up to 14 days without any other additional flea products.

Can you use oral flea & tick medications with this shampoo product?

This flea product is sufficient in killing fleas and ticks without any other additional flea products.  

How does this product work?
This product combines these active ingredients:

This combination plays a crucial role in existing infestations, because:

• In an existing infestation you might only be aware of the adult fleas, which only represent around 5% of the full infestation and are found on your furry family members.
• Immature flea life stages (flea eggs, larvae and pupae) which live in your furry family member’s environment consist of around 95% of the infestation and can be almost invisible to the naked eye.
• Insects have enzymes in their bodies that break down some insecticides. PiperonylButoxide stops some of these enzymes and allows the insecticides more time to work.
