FAQ

How soon will I see results?
Most topical treatments begin killing fleas within 12–24 hours; oral tablets like Capstar act in 30 minutes but do not prevent reinfestation.

Can I use more than one product at once?
Only combine products if explicitly approved by your veterinarian; overlapping active ingredients can cause overdose.

Are natural options effective?
Essential-oil sprays and diatomaceous earth provide limited relief and are rarely sufficient for established infestations.

Bottom Line Recommendation

For most households, start with Revolution Plus if broad-spectrum protection is needed or Advantage II for straightforward flea control. Pair any treatment with thorough home vacuuming and washing of pet bedding to break the flea life cycle. Consult your vet before starting, especially for kittens or cats with health conditions.
