a helpful product, fragrance is nice but very strong! a spray like “Flea-Free Breeze”, which not only kills fleas but also keeps flea eggs from developing into biting adults, is a valuable tool in controling and preventing fleas in your home. i bought this product once, and it worked fine. there wasn’t an unpleasant chemical odor. the fragrance was pleasant, but any time i used this product in our home, it would cause my husband and i both to start sneezing horribly. we’ve used other brands of flea-killing fabric spray as well as Febreze in our home in the past without having this kind of problem, so i never expected to have this kind of reaction. a fabric spray that both kills fleas and provides a fresh fragrance really is a great idea, but if you’re even the least bit sensitive to perfume-y, artificial fragrances (which we generally aren’t), you should probably steer clear of this product.
