Good product. Like that it’s low smell which is helpful for those who have issues with the strong smelling fly sprays. Con - can be a big pricey. Having said that, I’m prepared to pay a bit more to have the convenience of knowing I won’t get the coughs when I use this and know any family members will be ok as well.

Works quickly with only a small amount. Smell is subtle. Made from over 90% natural ingredients. Watch out for when it’s on promotion
