Can Fleas Become Immune to Capstar?

You’ve probably heard of Capstar, the recently introduced flea control product from Novartis. This treatment is effective for heavy flea infestations, but its main drawback is that it does not kill the juvenile flea stage. In the days following the treatment, the fleas will develop into adult fleas and you may have to treat again. To get rid of the parasites for good, you may need to use another product for a longer period of time.

Incorrect or regular use of Capstar can lead to side effects, including nausea and vomiting. However, these effects are rare. While most Capstar side effects are mild, you should monitor your dog’s behavior to make sure that it does not react aggressively. Other side effects in dogs and cats include increased heart rate, fever, and salivation. Some dogs and cats may also develop vomiting, diarrhea, and loss of appetite.

Another alternative to capstar is to use a chewable flea treatment. Chewable flea treatments are effective and less toxic than pesticides. One such product is Comfortis, which works by killing fleas and ticks at the point of contact. This product is recommended by veterinarians and lasts up to a month with a single dose. The active ingredient in Comfortis is a natural substance called Spinosad, which has been thoroughly tested by the Environmental Protection Agency.

Another product to try is diatomaceous earth, which you apply on your pet’s fur. This can have a toxic effect on asthmatics, and you should not use it on a windy day. The most effective way to prevent fleas is to treat the home as well as your pet’s fur. Since 80% of the flea life cycle occurs in the home and yard, it’s important to treat your entire home with flea prevention products.
