flea killer magic

works amazing on my 100lbs Golden Pyrenees mix. it is a 1 day treatment for flea infestation only this is not a preventative treatment this will only kill the adult fleas on your pet. and prepare your for baby for a pretty stressful 4 hours if they are heavily infested as this will make the fleas bite in order to poison them and affectively kill them. it will kill 90-100% of the adult fleas you will still need to treat and remove all the flea eggs and larva with a flea comb after bathing.

Flea Free

This was fast acting. We gave one pill to our dog and by that night he was flea-free.

Works 24/hrs

Works great! Does kill fleas in 24hrs. At least my dog it did. But she wasn't infested with fleas. i didn't realize that this was not a monthly flea pill just a 24hr pill. Make sure to get the monthly killer with it.
