We also use Frontline for ticks and Fleas and haven't had any problems with either. I have not heard of Chiggers , so I started looking on the Internet. It sounds like they can be in Ohio, but most the sites I found talked about them being a problem in the middle-south part of the US-states like Texas, Missouri, Arkansas, etc.

$18.50 is alittle more then we pay (about $13/dose through the vet), but I gues since there isn't as much of call for the medicine in Utah they think they should charge more
