Or if you want a no cost solution try "Diamataceous Earth". It's all natural & can be used on dogs or cats. It's just ground silica. Must be the "food grade" kind. You can get it on Amazon. Just dust it on them... totally safe. Just make sure you or your pet don't inhale it cuz not good for your lungs to inhale well, not "no cost" but low cost. I paid like $15.00 for a 10 lb.bag. I dusted my dog (with a sock over her nose. lol) 2 weeks later still not 1 flea. Look it up major health benefits for humans also. You tube or google it.
All I know that for cats they used Revolution which worked perfectly for me and I think it cost ~$20
