AMAZING! Killed the fleas within 30-40 minutes

These pills started working very quickly. I started seeing dead fleas on my pets within 30 to 40 minutes. I waited for several hours to make sure all of the fleas got a good dose of the flea killer and then gave my pets a good washing to remove all the dead fleas. I did not see any live fleas on them after I treated them. I also sprayed all of areas where my pets hang out with a flea killer and washed all of their bedding. Note: The pills start killing fleas immediately but it only works for 24 hour. A few days later, I did see a couple of fleas on two of my dogs so I retreated them and I haven't seen any sense. They probably picked the fleas up when they went outside to potty. I would recommend this product.

Gets rid of all fleas within 30 minutes. Works perfectly. Only need one pill. May repeat again if needed in a few days. Does not get rid of flea eggs so you will still need to use a monthly topical or oral flea prevention as well. This medicine Gives instant relief to your pet and then you'll need to treat the Pat with a flea medicine.
