They don't die after engorging. If they did, they would all die after feeding!

i looked at the frontline website. their claim is that when a tick bites a treated dog, the tick dies. i assume this would mean the tick died BEFORE it gets engorged with blood from the dog.

obviously, this tick has been on a dog for at least 2 or 3 days or more. i checked the expiration date on the packages before i used them because they were left over from last fall and they had not yet expired.

so, why did this tick not die once it bit??

I'm sorry! I misread your question! I hope someone (with a brain, as opposed to me!) answers your question. :)

LOL elly! thanks for clearing that up. i thought *I* was losing what's left of my mind!

Maybe the ticks get immune to the meds like fleas. I was freaking out oo when my dog who is on flea meds kept getting fleas on her...and I know they were biting her becuase I found flea dirt.

I have no idea myself, but my Frontline Plues packs just arrived from Amazon yesterday and I'm planning on treating both my furkids this afternoon. I was under the impression this stuff would repel and kill fleas and ticks. I'll check back here to see if someone in-the-know can answer your question.

In my opinion.

Frontline plus dog flea control just wasn't doing a good job and had such a strong odor that lingers for a week. Then I tried Advantage by Bayer and it works wonders, plus it has hardly any scent. Seems like it cost slightly more but so well worth it. I always check the expiration date to before I buy flea control.

Has anyone else noticed the difference?

Maybe it hadn't bit your dog since the frontline was applied. There are a number of scenarios as to why you might find a live tick in your home.

I have two cats and a dog. I use Frontline on all of them and I have never seen a tick or a flea in my home.

Lynn, Frontline does not repel fleas. It kills them, their larvea and renders their eggs infertile so more don't hatch.

According to the Frontline website, it kills "up to 100% of ticks within 48 hours" so it is very possible for a tick to become engorged before it dies.

If you want a faster tick-killing product, then I would use the PrevenTic collar. It has amitraz so you have to be careful about touching the collar yourself, or having kids or other pets touch or lick it. But it works really well. One collar lasts 3 months. I know people who just put it on their dogs when they go outside or to certain parks and they are happy with it. I haven't used i myself.

The tick probably disenganged itself from the dog because it was getting ready to die. Give it a couple days and see if its still alive... :-)

I smile because I would have incinerated it before check to see how long it lives.
