I used to use Sentinel and never...ever...had a problem with fleas. I used Frontline as a backup (extra support for traveling or going places. My vet changed what I used and my life has never been the same. The vet told me they don't make Sentinel anymore. I can't get anyone to confirm that for me though. I've used several things, including revolution with Frontline. Nothing has worked as well. Recently, about a week after giving them Revolution, I found fleas. I bathed them in flea shampoo, sprayed them, and put Frontline on them. Nothing worked until I gave them a Capstar. The last time I gave them a Capstar, it didn't work right away. I've now hired a Bug Man to come spray my yard and house. The fleas are not going away in the house (don't see them on the babies though)! I feel your pain! Good luck! |
