Whats better frontline or vectra ( vectra $93.00 6 months?)?

none of them i have used lavender oil and eucalyptus oil after i bath my dog . a few drops on there coat rub it in and do this 3 times a week and no fleas!! mine has never had them and he even plays with other dogs..it costs 8 dollars AUD per bottle but mix both oils when doing this good luck

have not heard of nor used vectra

Frontline has worked excellently for us
