Vet Review While this product offers an economic alternative for killing/repelling  fleas and ticks for 5 months, as well as preventing the development of flea eggs into larvae and adults,  I have personally not found this product effective in my experience and opinion.  The clients I have spoken to who have been pleased with this product have found it more effective as a flea preventative, rather than once an infestation already exists, where other products such as topical front line or advantage would be preferred.  I have also seen that in some dogs local skin irritation and hives can occasionally occur in sensitive pets, which usually resolve once the collar is removed. I also have concern for cancer and neurological effects with exposure to any prolonged pesticides.  While it is a nice benefit that the collar works even when wet, because of my concerns about overall efficacy and safety, I do not recommend use of this product.  I give it an overall rating of a 2 with an efficacy a 2 and ease of use a 5. Parastar Plus combines the proven performing main ingredient of fipronil with cyphenothrin, which allows for more rapid killing and treatment of fleas, ticks, certain mites, and lice. This combination allows for this topically applied product to begin killing within an hour. In my experience, most of my clients have reported higher efficacy and better satisfaction for tick control over fleas. It seems to be easier to dispense out of the applicator over competitor products, and especially with lighter colored dogs the product does not seem to stain. However on occasion, I have seen a sensitive darker coated dog have some mild bleaching at the site of application. With some longer haired dogs, I have seen it leave an occasional slightly sticky spot at the site of application as well. Like many of the competitor products, it is touted as waterproof, however, I try and recommend that clients do not bathe dogs for 2 or 3 days before or after application, as some feel that this may affect the efficacy of the product. In my experience, I have found that this product is better at preventing problems rather than controlling already heavy flea infestations, in which case I usually will go to one of the newer oral tablets for flea/tick control that usually kill rapidly within 30 minutes. Another limitation of the product is that you can't use Parastar Plus on less than 4-pound dogs, which is an added benefit of topical prescription products like Revolution. As with any product of this type, occasional itchiness, and/or irritation/agitation from applying the product may be seen, but I find this side effect less common than with competitor products. It is also important for clients to understand that it is critical, especially with heavy flea infestations, to also focus on treating the environment as well. Overall this product has performed better for tick control and prevention than for fleas. I give it an overall rating of a 3, with an ease-of-application rating of 4.5 out of 5.
