Entofenprox--Sargents silver--safe to use?

Hi, I just now found what I think was a flea on Robin. (Second floor, indoor cat, and I use off when I'm out to repel any possible fleas, so go figure...)

He's right on time to get another dose of flea meds. I found Sargent Silver in my cabinet with Entofenprox in it and am having trouble finding info on it. It's not Revolution, I know, but is it even safe?

Absolutely safe. I put sergeants one spot on my child and it works like a charm. If you've never used anything on him it'll take 3 months to work but it will. Yep, inside or out or both they need it. I wonder what pet parents did before even flea collars? I have a question I'm hoping someone can answer. Annabel has an infection and wants to stay under the bed. I say not good because air doesn't circulate under there so we compromise but in lieu of going outside to flush it, not good plus she's a bit disoriented, is under the bed really safe with no free flowing air? It's against the wall and no cross breeze in the apt.

Many here do not recommend the use of Hartz, Sergeants or Sentry flea products. There is major question as to their safety.

The safest products are Frontline, Advantage, Revolution and a few others that you can get via your vet.

You can also use CapStar first, which will kill all adult fleas within 24 hrs (usually quicker) and then apply a topical the following day.

Many flea collars are rather dangerous, esp for cats  (they say for dogs they arent as dangerous).

I know Bayer has now began to make their own flea collars, so these must be safe - Bayer is a well known human medical and vet medical enterprise.  But some of the others are excellent to use for chemical warfare, almost á la wwI.

The problem with flea collars (or one of the problems) is toxin exposure to the humans around the pet. Here is what I posted for a person asking about the safety of Sorresto flea collars, but the info pertains to all flea collars:


"If you read the warning label on Soresto, it advises to not let the cat sleep in bed with humans while wearing the collar and to not let children touch the collar. That sounds pretty toxic. When you think about it, flea collars are basically a ring of insecticide constantly near your cat's face for a really long period of time (8 months, in the case of Soresto). That cannot be healthy. Like most OTC flea products, they are mininally regulated and can be very dangerous. There are much better, safer alternatives for flea control. Then, there are all the scary human exposure studies that have been coming out over the last few years.

This is copied from an article I saw a few months ago (it sounds a little choppy because I just included the important bits):

The risk comes in when adult humans interact with or play with their pet while the pet is wearing a flea or tick collar. The humans get exposed to approximately 500 times the Environmental Protection Agency’s safe level of pesticides. This is according to a recent study by scientists at the Natural Resources Defense Council. Since children are that much smaller, their level can be 1000 times greater than what is safe for their bodies to be exposed to. The study is a first of its kind.
External flea and tick products that contain certain pesticides leave residues on a pet's hair or fur that have the ability to cause brain damage and affect the nervous systems of both the pet and human being.
Read labels carefully because stores are still selling these products and the government does not have firm safety assessments in place to protect pets and pet lovers from the dangers the products possess.

And another:

Flea-collar manufacturers include warnings on the products to avoid exposure and to wash your hands thoroughly after handling the collars. Research has shown these measures are not enough to limit exposure. Studies have shown that, after just three days, residue from the collars on pet fur exceeded acceptable EPA exposure levels for children. Even after two weeks, 75 percent of pets still have unsafe levels of toxins."



In my experience, either Advantage or Frontline, both now available OTC, do a fantastic job of killing fleas safely. It depends on where you live, though. Fleas here in northern Virginia have become immune to Frontline, so we have to use Advantage.
The only place flea collars should be is in your vaccuum cleaner bag. :nod:

Thanks, all. Mightily confused. Having caught the critter in my cats hair--sure looked like a flea, and yet it didn't jump?--I did the wet paper towel test to look for flea dirt and came up empty handed. While it's very possible it was a flea, I've also had springtails recently in the same window Robin had been in just before I found the critter in his fur. So I'm not as panicked.

So I've decided to hold off on the Sargents for now, and pick up something from the vet. He was on Frontline, but only because my favorite sister had bought me a three month supply. Now that it's high summer, it's time for Revolution.

However, and maybe I need to start a new thread, but in my searching I found something called Frontline Tritek? Has anyone used it? It's extremely cheap on some sites...

That also said, there was a recent thread on the stuff in Revolution, being sold overseas in a different name for about half the price. ) If anyone knows the name of it, can you post it here or message me? Thanks!
