biospot and frontline plus do have one active ingredient that is the same, methoprene. However, there is a huge difference between Pyrethrin, which is used in most common lawn and garden pesticides, and fipronil. While fipronil is also a pesticide, it's also commonly used to kill roaches, ants and termites.
Pyrethrin however breaks down quickly when exposed to sunlight and oxygen. That means it looses it's efficacy quite quickly once it's applied. It's also highly toxic to cats in particular.

Never trust a tall dwarf... he's lying about something.
I used BioSpot in the past and I can tell you from experience it does not work very well. At first it seemed to work, but within a few days the dogs were loaded with fleas again. I have several dogs and chose BioSpot because it was not as expensive as the other brands and it was always advertised as being more effective than the others. I recently found that Frontline now has a spray I asked on here if anyone had ever tried it and I received no response, but I tried it anyway. I can say so far so good...It seems to be really working. So far no fleas on the dogs or cats and any that I see are dead!! Hooray!! So, if you have several pets it may be something you might consider looking into.
From collars to sprays to topical solutions, Americans spend half a billion dollars on flea control products every year and unwittingly poison themselves and their animal companions. There are safer, more environmentally friendly ways to protect your furry friends and yourself from these pesky insects.
Honestly, I have not had much luck with either. I think it is frontline I used last month. I do the treatment every month on the first when I give them their interceptor for heartworm. But when I went to treat them this month my little one had 6 visible fleas. I was wondering what one of the flea and tick treatments are the best. I have used Frontline, revelution, advantix, advantage, and several of the "OTC". I have found that Adams seems to be the best for treating the environment. Thier flea and tick bombs are WONDERFUL. I have used their powders too. The spray worked well too and though it did smell like alcohol, the smell was more tolerable than what the dogs smell like when I used the frontline. They smelled like oil all month. And you cant bath them because it is not waterproof. In my opinion... I like Reveloution the best. What do you guys think?
