My pets react badly to the monthly treatments so since they are all indoor pets, we just make sure they are bathed, at least once a month for the dog (she also swims in the pool a lot). The cats all get full baths too. We've never had flea or tick problems. I'm very allergic to flea bites so I'd be the first to know. We're also careful to keep them away from any other pets that could have fleas too. The only time I do use a treatment is right after they are boarded for vacations. We only use Vet prescribed treatments too. The rest of the time, regular baths work for us.
