Rated 5 out of 5 by from This stuff really works !! This stuff really works !! The trigger dispenser allowes for an even coat without misting too much - it sprays but does not go airborne which I love. I have noticed a huge drop in pests especially spiders. I love that this also keeps ticks away which are super scary this year. And not harmful to pets ! Most importantly once dried there’s no residue!! Amazing.
