- Treat all pets in the home – If one pet has fleas, all must be treated simultaneously.
- Wash bedding and vacuum daily – Hot water kills flea eggs. Vacuum carpets, furniture, and cracks in floors.

- Don’t mix treatments – Never combine two flea products unless your vet approves.
- Stick to a schedule – Monthly treatments work best when given on time every month.

Oral treatments like NexGard kill fleas within hours. Topical products may take 12-48 hours. You’ll see dead fleas falling off your pet within a day.
Q: Are natural flea remedies effective?
Diatomaceous earth and essential oils can help but are rarely enough to eliminate an infestation. For severe cases, stick with veterinary-approved products.
