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.

Works great keeping away house flies!

Live in Southern California near a nature preserve surrounded by neighbors who don't clean up after their dogs or have a pack of SEVEN semi feral indoor/outdoor cats, and neighbors across the street with horses and pigs in their yards. Conditions are positively RIPE for flies! Started using this last summer (2022) and as long as i kill any flies that do get in, haven't had a problem in 2 summers which is amazing. Can't exaggerate the fly issues, it's like a horror movie. but as long as I use this regularly, like once a month (1 bottle is 2 treatments for a townhouse spraying around and on windows and doors patio and balcony on 1st and 2nd floors) we're good. I'd say it takes a full bottle before you see consistent fly repellent but maintain it to the point where you can catch a wiff of the product when you're outside and boom done. I do have one dog and I can smell this product when I walk through the door rather than animal waste and and standing water stink from the sprinkler system, and can definitely see and smell the difference throughout the neighborhood compared to my treated area. If I could convince my hoa to include a monthly treatment in the landscaping we'd be set! As if hoas care about anything lol. I went a few weeks without refreshing and we were pretty quickly swarmed with flies (thanks tropical storm hillary). So def refresh after rain in CA. I stop treating when Temps drop to the 30s overnight, then start again in May. A nice pine smell that keeps the flies away. Highly recommend even if you live in a townhouse with shared walls and outdoor space I think it creates a little bubble. Only thing is the nozzle that attaches to the house can be leaky if you don't get it on good and tight but not chemicals so

We have three puppies in the back and we’re concerned about the flies biting them and that’s when I found this here in chewy . This stuff was absolutely trash ! It did nothing to even ward off not one insect . This was a total waste of money ! Stay clear !

Mosquito Friendly!

Did absolutely nothing to deter mosquitos. So disappointed. It was as if I just sprayed water. No difference whatsoever.

Didn’t Work

That’s it - it didn’t work. Used it three consecutive times and we still have flies all over in our grass. Wasn’t effective even a little bit. Waste of money and time for us. Bought it because it said it was safe for animals.

Does the job

This spray makes my yard smell like flowers. I love it. I didn’t notice last summer it repelling flea, tics, blackflies or mosquitoes. My pups are on flea meds tho. I mainly buy it for the smell. Very pleased.

So Far, So Good & LOVE the smell

My 6 month old puppy has had recurrent giardia (aggh!), with more rounds of meds than I can count. I found a body of research that supported the use of cinnamon and clove oil, so I gave this a try. So far (fingers crossed and knocking on wood) she has not reinfected herself! The smell is amazing, but as other reviewers note it is used up fast. I have small lawn area and it is not very expensive so I use it each week and it is fine. Although I wish it came in a larger size. In the summer I may need more bottles to use in other areas of my yard to keep other pets a way as the label notes. If you are thinking about it, it is worth giving it a try. I have 3 dogs and the initially strong, but pleasant, holiday-like smell does not seem to bother them at all.
