Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Questions & Answers

3 Customer Questions

My dog sleeps with me. Once it drys, is this safe for humans or would you have to keep the dog away from you for 24 hrs?
Answer by ChewyApr 10, 2019
It's recommended to keep treated pets apart from each other, other pets and children for 24 hours after treatment and until the product is dry. This helps prevent pets from ingesting the topical by licking or grooming one another.

Does PetArmor Plus withstand bathing. How long do we wait after applying to bath the dog?
Answer by ChewyAug 18, 2022
This product is waterproof and remains effective for 30 days. After applying the product, you will want to wait until the application area is dry before allowing your pet to get wet, usually around 24-48 hours. Your pet may be bathed in a gentle grooming shampoo after the product has dried.

Does Petarmor have an expiration date? If I buy a one year supply (2 6 month supplies), will it pass the expiration before the year is up?
Answer by ChewyJun 23, 2022
When properly stored and under ideal conditions, the product has a three-year shelf life. If there has been a variance in temperature (extreme heat for example), it may reduce the effectiveness of the product. Be sure to store the product in a cool (below 77°F/25°C) dry place inaccessible to children and pets. Do not refrigerate and protect from direct sunlight.
