I think it was Dateline that I saw Frontline causing animals to have fits of vicious vomiting after they ingested small amounts of it. Revolution is what I give my animals and it protects against fleas, tick, all types of worms and other malady's. While living in the midwest, our school would do regular checks for lice and ticks about once a month. I hated waiting in line for someone to pick through my hair. I've had several ticks on me found in this manner. For removal, they would heat a needle up to red-hot and then singe the sucker so that it would release it's grasp before being grabbed by tweezers.
