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.

Can this product be used in conjunction with K9 Advantix?
Answer by ChewyApr 27, 2020
It is not recommended to use this spray in conjunction with another flea/tick treatment. This spray is a great alternative to monthly topical solutions and should be reapplied every 9 days.

Does this product contain citronella or lemongrass? They are not listed as active ingredients but I wanted to be sure as I am allergic to both.
Answer by ChewyJul 18, 2019
This product does not contain citronella or lemongrass.

Is it safe to spray on a concrete surface where cat feeding bowls are placed?
Answer by ChewyJun 17, 2021
It is recommended by the manufacturer to not get the product directly in food or water. If your pet has a tendency to spill food or water then eat or drink it up, do not spray near the bowls."

it worked, the flies left my dogs alone but its a tiny bottle and some of it leaked out into the plastic it was wrapped in. needs more secure packaging.

The bottle is tiny and when it arrived, most of the bottle content leaked at the bottom of the box because the top was not securely tightened.

Fly spray

Sorry I haven't needed to use it yet. Got it for my big Rottweiler as the flies were so thick but the items did not get here in time to use them. He passed away.

I love this stuff! I wish it came in bigger containers!! It is the best to keep the flies away from my dog's area.

Horrible packaging

The sprayer is far too large for the bottle, which makes it top-heavy. Because of that, it constantly falls over and leaks, even if the top is tightly screwed on (not overtightened, just normal).

Received product in a taped up zip lock baggie and over half the product leaked out. Waste of money.

Awesome stuff - works great!

The horse flies around our property are tenacious. Our poor doggo gets swelling around the area they bite her. Flys-off keeps those pernicious little suckers off her so that she can enjoy our outdoor walks. Very pleased with this product and that it is safe for cats so that I don't have to try to scrub it off her before she goes back in the house with our kitties.

Great for hiking

This works better than anything I've found for keeping all variety of bugs away - and it actually has a pleasant odor.
