I LOVE Bio-Spot Flea and Tick Control.  I like the citrysy smell and even more, I love the price.  At least I like the price when purchased from ValletVet.com.  Especially when you catch it on sale.  You can sign up online for a ValleyVet.com newsletter which will tell of all their products on sale weekly.  I also have horses and live on a farm, so I use ValletVet and Bio-Spot often.  And no---I do not work for them.  :-)  Good luck with your precious pets!  Give this product a try--you will like it.
