Regular Vacuuming
Vacuum carpets, rugs, and upholstery frequently to remove flea eggs and larvae. Dispose of vacuum bags immediately.

Yard Maintenance
Keep grass short, remove debris, and consider nematodes or diatomaceous earth for outdoor control.
Pro tip
For maximum effectiveness, treat your home and pet simultaneously. We recommend starting with a thorough cleaning followed by a home spray, then applying a pet spray or chew according to the label directions.
Frequently asked questions
Are organic flea treatments as effective as chemical ones?
Organic treatments can be very effective for prevention and minor infestations, but may require more frequent application. For heavy infestations, chemical options might work faster.
Can I use dog flea treatment on my cat?
No, many dog products contain ingredients toxic to cats. Always choose a product specifically labeled for your pet species.
How often should I apply organic flea spray?
It depends on the product. Most recommend reapplication every 7-14 days or after your pet gets wet. Always follow label instructions.
Are organic flea chews safe for puppies?
Check the product label for age and weight restrictions. Many are safe for puppies over 12 weeks, but consult your vet for very young or small dogs.
Do home sprays stain furniture?
Most organic sprays are water-based and unlikely to stain, but test on an inconspicuous area first. Allow to dry before pets contact treated surfaces.
