15 Customer Questions
How long does it take for it to start killing the live flea's?
Answer by • Feb 12, 2018
You should begin to see results within 12 to 24 hours after applying. This product stops the flea life cycle and kills flea eggs and larvae for up to 12 weeks.
Does the treatment kill ticks that are already on your dog prior to application?
Answer by • Sep 03, 2024
This product can take some time to work on ticks, especially if they have already latched on. No product will be able to prevent a tick from crawling on your pet. The product should begin to kill within 24-48 hours but may take up to 72 hours to reach its full effectiveness.
How do you apply it?
Answer by • Jul 18, 2023
To apply this treatment, invert the tube over the dog and use the open end to part the dog’s hair. Apply as a spot to the dog’s back between the shoulder blades. Squeeze tube firmly to apply all of the solution to the dog’s skin.
Does this work for mosquitos?
Answer by • Jun 21, 2021
